The alveoli are located in the lungs. They are used to move carbon dioxide and oxygen between the lungs and the bloodstream.

What is the role of the alveoli in the respite system?
Alveoli exchange Oxygen with blood in capillaries
What protects the alveoli?
The alveoli are protected by the surfactant, which is a substance secreted by the alveolar cells. Surfactant reduces the surface tension in the alveoli, preventing them from collapsing during exhalation. The rib cage and diaphragm also play a role in protecting the alveoli by maintaining the pressure required for proper lung function.
Where in the breathing system do the changes in the gas content of air happen?
Changes in the gas content of air occur primarily in the alveoli of the lungs. Here, oxygen from the inhaled air diffuses into the blood, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. This exchange is facilitated by the thin walls of the alveoli and the extensive surface area provided by the lung tissue. Thus, the alveoli play a crucial role in gas exchange within the respiratory system.
The role of surfactant in relation to water?
Surfactant is used in the lungs to break water tension within the alveoli. Without it, the alveoli will collapse and you will suffocate and die.
What is the role of alveoli in the breast?
Alveoli in the breast are specialized structures that play a crucial role in lactation. They are small, sac-like glands lined with milk-secreting cells called alveolar cells, which produce and store milk during breastfeeding. When a baby suckles, hormonal signals trigger the contraction of myoepithelial cells surrounding the alveoli, forcing milk through the ducts to the nipple for the infant to consume. This process is essential for nourishing the newborn and providing essential nutrients and antibodies.
What are the small holes in the intra-alveolar septa?
The small holes in the intra-alveolar septa are known as alveolar pores or pores of Kohn. These openings connect adjacent alveoli, allowing for the equalization of air pressure and facilitating the exchange of gases between neighboring alveoli. They play a crucial role in maintaining lung function by promoting collateral ventilation, especially in cases where some alveoli may be obstructed.
What connects the respiratory and circulatory system?
Alveoli
What is the function of alviole?
Alveoli are small air sacs located in the lungs that play a crucial role in the respiratory system. Their primary function is to facilitate the exchange of gases—oxygen and carbon dioxide—between the air and the bloodstream. The walls of alveoli are thin and surrounded by capillaries, allowing oxygen to diffuse into the blood while carbon dioxide is expelled from the blood into the alveoli to be exhaled. This exchange is essential for maintaining proper oxygen levels in the body and removing waste gases.
What do septal cells do?
Septal cells, also known as Clara cells, are found in the respiratory bronchioles of the lungs. They produce surfactant, a fluid that helps reduce surface tension in the air sacs (alveoli) of the lungs, preventing them from collapsing. Septal cells also play a role in protecting the airways from foreign particles and toxins.
What does the avleoli do?
Alveoli are tiny air sacs in the lungs that play a crucial role in the respiratory system. They facilitate the exchange of oxygen and carbon dioxide between the air we breathe and the bloodstream. This process occurs through the thin walls of the alveoli, allowing oxygen to enter the blood while carbon dioxide is expelled. Their large surface area maximizes the efficiency of gas exchange.
