Flash cards every weekday: 🤍 The alveoli ("many alveoli", "one alveolus") are the sites of gas exchange in the lungs. They are tiny air sacks sometimes described as being cauliflower-shaped. Oxygen diffuses across the lining of the alveoli and blood capillaries into and into red blood cells. Carbon dioxide diffuses from the blood to the alveoli. A concentration gradient is maintained by breathing as well as blood flow. The main adaptation of the gas exchange surface are: 1. Large surface area 2. Thin wall 3. Moist lining 4. Good blood supply 5. Good ventilation
Official Ninja Nerd Website: 🤍 Ninja Nerds! In this lecture Professor Zach Murphy will be teaching you about Surface Tension and Surfactant in Alveoli. We will be outlining the significance of the air-water interaction in the alveoli of the lungs. We talk about how this air-water interaction increases the tension within the alveolar walls, increasing the collapsing pressure of the alveoli. We also discuss Laplace's law and show a diagram of the histology of the alveoli. In addition, we talk about surfactant and its function to naturally act to decrease surface tension. In the presence of a pathology, when surface tension is high and surfactant production is low, this can lead to infant respiratory distress syndrome, which is described in this lecture.

Alveoli are the tiny balloon-shaped sacs at the distal end of the bronchial tree. Watch this video for the medical definition and a brief overview. 💥Alveolar Ventilation [Full Guide] ➜ ➜ ➜ 🤍 ➡️ Alveoli Overview They're made up of type I and II pneumocytes which make up only a very thin layer that facilitates the passage of oxygen and carbon dioxide molecules. During a breathing cycle, we take in oxygen during inhalation while removing carbon dioxide during exhalation. Air is inhaled through the mouth and nose where it passes through the trachea, bronchi, bronchioles, alveolar duct, and then into the alveoli where gas exchange takes place. This process is known as alveolar ventilation. Alveoli rely on a substance known as surfactant which helps to maintain their shape and surface tension. Without surfactant, the alveoli would collapse which is known as atelectasis. Barotrauma is another potential problem that can occur in the alveoli. It's an injury to lung tissue that results from overexpansion due to increased levels of pressure or a tidal volume that is too large. ➡️ Alveolar Pulmonary Diseases: - Emphysema - Pulmonary edema - Pneumonia - Tuberculosis - Acute respiratory distress syndrome (ARDS) - Pneumoconiosis - Lung cancer 💥Alveolar Ventilation [Full Guide] ➜ ➜ ➜ 🤍 ————— 📗 BEST STUDY GUIDES FOR YOU ▪ TMC Test Bank 👉 🤍 ▪ Hacking the TMC Exam 👉 🤍 ▪ TMC Exam Bundle (Save $) 👉 🤍 ▪ Daily TMC Practice Questions 👉 🤍 💙MORE FROM RTZ ▪ Free TMC Practice Exam 👉 🤍 ▪ Free RRT Cheat Sheet 👉 🤍 ▪ Resources for RT's 👉 🤍 ▪ Testimonials 👉 🤍 🌐FOLLOW US ▪ Instagram 👉 🤍 ▪ Twitter 👉 🤍 ▪ Facebook 👉 🤍 ▪ Pinterest 👉 🤍 🚑MEDICAL DISCLAIMER This content is for educational and informational purposes only.

The respiratory system is one of the favorites of our production team. Thus, visualizing the pulmonary alveoli was an excellent opportunity to show their masterpiece. We hope you enjoy this fragment. How does a pulmonary alveolus look like? A pulmonary alveolus has a shape of a hollow cavity located in the parenchyma of the lung. It is the functional unit of lungs and the basic unit of ventilation. A capillary network covers about 70% of the area of each alveolus. An alveolus of an adult human has an average size of two hundred micrometers in diameter, which increases during inhalation.

Lung anatomy and physiology of gas exchange in the lung alveoli during respiration nursing lecture. This lecture details the anatomy of the lungs and how gas exchange in the lungs takes place between carbon dioxide and oxygen. The lung is made up of many components that participant in gas exchange. Inhaled air with oxygen enters into the upper respiratory system via the nose or mouth then through the nasal cavities, larynx, and trachea which splits at the carina into the right and left bronchus (primary bronchi). The primary bronchi and pulmonary vein and artery enter into the lungs at the hilum. The pulmonary artery delivers unoxygenated blood to the lungs, and the pulmonary vein delivers oxygenated blood back to the heart. The primary bronchi branches off into the lobar bronchi (also called secondary bronchi) then into the segmental bronchi (also called tetiary bronchi), and then into even smaller areas such as the bronchioles. The bronchioles connect to the alveolar sacs via the alveolar ducts. Gas exchange occurs in the alveolar sac within the alveoli. The alveoli sacs contain capillaries that help with transporting carbon dioxide and oxygen in and out of the body. The pulmonary artery brings unoxygenated blood through the capillary and carbon dioxide transports across the thin capillary wall and is transported out of the body through exhalation. Then the inhaled oxygen transports across the capillary wall onto the red blood cells which is taken via the pulmonary vein back to the heart to replenish the body with fresh oxygenated blood. Other facts about lung anatomy: the right lung has three lobes while the left lung has two lobes. The lung is made up of two layers: visceral pleura (surrounds the lungs) and parietal pleura (attaches to the thoracic cavity). In between these layers, is a small space of fluid that allows the lungs to glide on each other during inhalation and exhalation.

Explore our entire animation video library at: 🤍 All videos from respiratory physiology: 🤍 Video Summary: This video is on functions of surfactants in alveoli in respiratory system. Alveolar wall is line with fluid. This fluid has surface tension that creates multiple problems. Like due to surface tension on the fluid, alveoli tends to collapse. It makes it harder to inflate the lungs. Second problem is fluid accumulation in the alveoli. As the surface tension tries to decrease surface area or collapse the fluid film, it draws fluid from interstitium into the alveoli. This increases thickness of fluid layer of alveoli. This increased thickness makes it more difficult for respiratory gases to diffuse through it. Third problem is, as per Laplace law, the smaller alveoli produces higher pressure on the air inside the alveoli as compared to the pressure generated in larger alveoli. So smaller alveoli collapses into larger alveoli. This collapsing decreases total surface area available for gas exchange. So such collapsing should be prevented. Surfactants by decreasing surface tension, solves all three problems. They makes it easy to expand lungs or in other words, increase compliance of the lung. Second, they prevent fluid accumulation in the alveoli and third, they prevent collapsing of smaller alveoli into larger alveoli. In the video, all the functions are described with help of animation. 🎞More videos on Respiratory Physiology: ● Transport of Gases - Oxygen Hemoglobin Dissociation Curve: 🤍 - Factors Shifting Oxygen Hemoglobin Dissociation Curve: 🤍 - Oxygen Hemoglobin Dissociation Curve during Exercise: 🤍 - Transport Of Carbon Dioxide: 🤍 - Carbon Dioxide Dissociation Curve: 🤍 - Haldane Effect: 🤍 ● Lung Mechanics - Alveolar Pressure and Pleural Pressure: 🤍 - Surface Tension in Lung Alveoli: 🤍 - Surfactants Mechanism of Action: 🤍 - Functions of Surfactants: 🤍 - Compliance of Lungs: 🤍 - Diseases Affecting Lung Compliance: 🤍 • Ventilation & Dead Spaces in Respiratory Tract: 🤍 • Lung Volumes and Capacities: 🤍 • What Determines Lung Volume?: 🤍 ● Follow me at: • Facebook: 🤍 • Instagram: 🤍 DISCLAIMER: This video is for education purpose only.

Explore our entire animation video library at: 🤍 All videos from respiratory physiology: 🤍 Video Summary: Surface tension is special force between water molecules on the surface. Oxygen and hydrogen atoms in water molecule are partially charged. Positive charge on the hydrogen atom of one water molecule attracts the oxygen atom with negative charge of the other water molecule. Water molecules deep in the water phase experience such attraction in all the directions so there is no net force acting on deep water molecules. However the water molecules on the surface have no other water molecule to pull them outside the water phase. So such water molecules experience net force towards the bulk water phase. As some water molecules are pulled deep in, the remaining water molecules on the surface develop tension. This is surface tension. In lung, alveoli are lined by fluid. And the remaining space in alveoli is filled with air. So there is air-fluid interface in alveoli. This interface tries to decrease it's surface area. And in doing so, they collapse alveoli. So extra pressure is required to expand the alveoli with high surface tension. 🎞More videos on Respiratory Physiology: ● Transport of Gases - Oxygen Hemoglobin Dissociation Curve: 🤍 - Factors Shifting Oxygen Hemoglobin Dissociation Curve: 🤍 - Oxygen Hemoglobin Dissociation Curve during Exercise: 🤍 - Transport Of Carbon Dioxide: 🤍 - Carbon Dioxide Dissociation Curve: 🤍 - Haldane Effect: 🤍 ● Lung Mechanics - Alveolar Pressure and Pleural Pressure: 🤍 - Surface Tension in Lung Alveoli: 🤍 - Surfactants Mechanism of Action: 🤍 - Functions of Surfactants: 🤍 - Compliance of Lungs: 🤍 - Diseases Affecting Lung Compliance: 🤍 • Ventilation & Dead Spaces in Respiratory Tract: 🤍 • Lung Volumes and Capacities: 🤍 • What Determines Lung Volume?: 🤍 ● Follow me at: • Facebook: 🤍 • Instagram: 🤍 DISCLAIMER: This video is for education purpose only.

Anatomical model descriptions for student learning.
Trachea, bronchi, bronchioles and alveoli The trachea, commonly known as the windpipe, is a tube about 4 inches long and less than an inch in diameter in most people. The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung. The bronchial tubes split up again to carry air into the lobes of each lung. The right lung has three lobes while the left lung has only two, to accommodate room for the heart, The lobes are filled with small, spongy sacs called alveoli, which is where the exchange of oxygen and carbon dioxide occurs. The alveolar walls are extremely thin (about 0.2 micrometers) and are composed of a single layer of tissues called epithelial cells and tiny blood vessels called pulmonary capillaries. Blood in the capillaries picks up oxygen and drops off carbon dioxide. The oxygenated blood then makes its way to the pulmonary vein. This vein carries oxygen-rich blood to the left side of the heart, where it is pumped to all parts of the body. The carbon dioxide the blood left behind moves into the alveoli and gets expelled in our exhaled breath. #LowerRespiratorySystem #LowerRespiratoryTract #StructureOfLungs

Air first enters the body through the mouth or nose, quickly moves to the pharynx (throat), passes through the larynx (voice box), enters the trachea, which branches into a left and right bronchus within the lungs and further divides into smaller and smaller branches called bronchioles. The smallest bronchioles end in tiny air sacs, called alveoli, which inflate during inhalation, and deflate during exhalation. Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli. The walls of the alveoli actually share a membrane with the capillaries in which oxygen and carbon dioxide move freely between the respiratory system and the bloodstream. Oxygen molecules attach to red blood cells, which travel back to the heart. At the same time, the carbon dioxide molecules in the alveoli are blown out of the body with the next exhalation. The primary function of the respiratory system is to exchange oxygen and carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of cells lining the alveoli and the surrounding capillaries are each only one cell thick and are in very close contact with each other. This barrier between air and blood averages about 1 micron (1/10,000 of a centimeter, or 0.000039 inch) in thickness. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body (see Biology of the Heart : Function of the Heart). Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through two large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide. Gas Exchange Between Alveoli and Capillaries: To support the exchange of oxygen and carbon dioxide, about 5 to 8 liters (about 1.3 to 2.1 gallons) of air per minute are brought in and out of the lungs, and about three tenths of a liter of oxygen is transferred from the alveoli to the blood each minute, even when the person is at rest. At the same time, a similar volume of carbon dioxide moves from the blood to the alveoli and is exhaled. During exercise, it is possible to breathe in and out more than 100 liters (about 26 gallons) of air per minute and extract 3 liters (a little less than 1 gallon) of oxygen from this air per minute. The rate at which oxygen is used by the body is one measure of the rate of energy expended by the body. Breathing in and out is accomplished by respiratory muscles. Air is brought to the alveoli in small doses (called the tidal volume), by breathing in (inhalation) and out (exhalation) through the respiratory airways, a set of relatively narrow and moderately long tubes which start at the nose or mouth and end in the alveoli of the lungs in the chest. Air moves in and out through the same set of tubes, in which the flow is in one direction during inhalation, and in the opposite direction during exhalation. During each inhalation, at rest, approximately 500 ml of fresh air flows in through the nose. Its is warmed and moistened as it flows through the nose and pharynx. By the time it reaches the trachea the inhaled air's temperature is 37 °C and it is saturated with water vapor. On arrival in the alveoli it is diluted and thoroughly mixed with the approximately 2.5–3.0 liters of air that remained in the alveoli after the last exhalation. This relatively large volume of air that is semi-permanently present in the alveoli throughout the breathing cycle is known as the functional residual capacity (FRC). At the beginning of inhalation the airways are filled with unchanged alveolar air, left over from the last exhalation. This is the dead space volume, which is usually about 150 ml. It is the first air to re-enter the alveoli during inhalation. Only after the dead space air has returned to the alveoli does the remainder of the tidal volume (500 ml - 150 ml = 350 ml) enter the alveoli. The entry of such a small volume of fresh air with each inhalation, ensures that the composition of the FRC hardly changes during the breathing cycle.

How exchange of gases take place in Alveoli? | Gaseous Exchange in Lungs | Respiratory System Exchange of respiratory gases, oxygen and carbon dioxide take place in the alveoli of the lungs. Oxygen which is inhaled from the atmosphere diffuses through the walls of the alveoli and reaches to the adjacent capillaries into the red blood cells. It binds to haemoglobin present in red blood cells and is transported to all the tissues of the body. Carbon dioxide produced by the metabolism reaches the lung via the blood. It then diffuses across the capillary and alveolar walls into the air to be exhaled out from the body. The alveoli of the lungs have a specialized structure for efficient exchange of respiratory gases. It has extremely thin walls. It has large surface area to volume. It is surrounded by many blood capillaries. Gas exchange in the lungs takes place at the alveolar level. Carbon dioxide diffuses across the alveolar membranes to be eliminated from the lungs during exhalation, and oxygen diffuses across the membranes in the other direction to be transported back to the heart where it is pumped out to all the body tissues.

So we all know that breathing is pretty important, right? Today we're going to talk about how it works, starting with the nameless evolutionary ancestor that we inherited this from, continuing to the mechanics of both simple diffusion and bulk flow, as well as the physiology of breathing, and finishing with the anatomy of both the conducting zone and the respiratory zone of your respiratory system.
