Where does passive diffusion occur in the lungs?
Passive diffusion occurs in the alveoli of the lungs. Oxygen from inhaled air moves across the thin alveolar membrane into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
When Air moves out of the lungs the pressure inside the lungs is?
when air moves out of the lungs, the air pressure decreases
Why is normal exhalation passive?
Normal exhalation is a passive process because it does not require active muscle contraction. Instead, it relies on the relaxation of the diaphragm and intercostal muscles, allowing the lungs to passively recoil and expel air. This passive process is driven by the elastic properties of the lungs and chest wall.
What is inspiration and exhalation?
Inspiration is the process of inhaling air into the lungs, while exhalation is the process of expelling air out of the lungs. These processes are vital for the exchange of oxygen and carbon dioxide in the body, which is necessary for bodily functions and maintaining life.
Air moves from the outside into the lungs through?
The air moves from the outside into the lungs through the windpipe.
What are the active and passive parts of breathing?
The active part of breathing involves the contraction of the diaphragm and intercostal muscles to expand the chest cavity, allowing air to enter the lungs. The passive part of breathing involves the relaxation of these muscles, causing the chest cavity to decrease in size and air to be expelled from the lungs.
What is the substance that moves from the bloodstream to the air via the lungs?
Oxygen is the substance that moves from the bloodstream to the air via the lungs during respiration. This process occurs in the alveoli of the lungs where oxygen is exchanged for carbon dioxide.
What happens in the lungs when you breathe out air?
the lungs will moves down when breathe out air
How air moves into and out the lungs?
breathing.
What moves air in and out the lungs?
the diaphragm
What force cause air to move in an out of the lungs?
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
When air moves into the lungs when the diaphragm muscles do what?
The diaphragm moves down to make the lungs expand (inhalation)
