Why does oxygen diffuse from an alveolus to the blood around it?
Oxygen diffuses from an alveolus to the blood around it because of the concentration gradient between the high oxygen concentration in the alveolus and the lower oxygen concentration in the blood. This process allows oxygen to move from the lungs into the bloodstream for transport to the body's cells.
Each alveolus is surrounded by a network of what?
Each alveolus is surrounded by a network of capillaries, which are tiny blood vessels responsible for the exchange of oxygen and carbon dioxide with the surrounding tissues. This network allows efficient gas exchange to occur in the lungs.
What is the difference between alveolar sac and an alveolus?
Alveolus is a single structure in the lungs where gas exchange occurs, while alveolar sac is a cluster of alveoli where multiple gas exchange processes happen simultaneously. Alveolar sacs are made up of multiple alveoli grouped together.
How many cells does an oxygen molecule have to pass through to get from an alveolus into the blood?
An oxygen molecule must pass through four cell layers to move from an alveolus into the bloodstream: the alveolar epithelial cells, the capillary endothelial cells, and their basement membranes. This process is essential for oxygen exchange in the lungs.
What is the lipid-based molecule called that coats the air-exposed surface of the alveolus?
The lipid-based molecule that coats the air-exposed surface of the alveolus is called pulmonary surfactant. Pulmonary surfactant reduces surface tension, preventing alveolar collapse and allowing for efficient gas exchange in the lungs.
What is the adjective for alveolus?
The adjective for alveolus (singular) or alveoli (plural) is alveolar.
What is the giant panda special feature?

What part of the mammary gland produces milk?
mammary alveolus
How can the blockage of the alveolus be removed?
Alveolar macrophage cells work to clear particles from the alveolus by phagocytosis. If this process is overcome by continued build up of particles then the alveolus becomes damaged. Once an alveolus is blocked there isn't much you can do.
What is the singular form of the word alveoli?
One alveolus is a singular, tiny air sac of the lung, surrounded by a network of capillaries, and through which oxygen and carbon dioxide are exchanged. A cluster of such air sacs are alveoli (plural of alveolus).
What is special feature about pride?

What is a special feature of the center of a hurricane?
The special feature at the center of a hurricane is a calm area called the eye.
What is special feature?
A special feature is quite simply an add-on. It is not part of the actual film or product, but was added on for your pleasure.
Name the process involved in the passage of gas between the alveolus and the blood?
The process involved in the passage of gas between the alveolus and the blood is called gas exchange. This occurs through diffusion, where oxygen moves from the alveolus into the capillaries and carbon dioxide moves from the capillaries into the alveolus.
