Since the volume of the lungs increases, the intrathotacic pressure decreases, and air moves into the lungs.

∙ 14y agoThe intrapulmonary pressure is greater than the atmospheric pressure and air is going to flow from high pressure to low pressure.

Does your chest expand because your lungs inflate or do your lungs inflate because your chest expands?
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
What are organs that expand to fill with air?
do you mean fills with air? if so then its the lungs
How does air flow between neighboring alveoli?
You use the respirerotry system. To be precise when air is to be sucked in, the brain askes the lungs to expand, which naturally creates a low pressure inside the lungs. Similarly when the lungs are compressed the air inside is flushed out.
Under what conditions does air tend to flow into the lungs?
Air tends to flow into the lungs when thoracic volume increases and pressure decreases. When the opposite is true, air leaves the lungs.
What organ expands to fill with air?
Lungs expand to fill with air. It is done during respiration.
When you exhale but dn't delibirately inhale why does air still flow into your lungs?
Because air diffuses from high pressure to low pressure, when we breath we aren't really "sucking" air in, our diaphragm lowers and our ribcage extends allowing our lungs to "expand" air then diffuses from the outside of the body into our lungs, when the diaphragm contracts it creates a higher pressure in the lungs compared to the outside, so air then diffuses from the lungs and out of the body.
How does surfactant affect the total air flow into lungs?
Surfactant is similar to a detergent, it keeps the fluid coating the lining of the alveoli from creating surface tension. This allows the alveoli to expand without hindrance, and allows greater air flow.
When the lungs expand does it fills with air from the atmosphere?
Yes
What happens to lungs when you inhale?
what happens when you inhale is that air goes into your lungs and your lungs get bigger ...Actually, your diaphragm moves to expand the volume of your thoracic cavity, which pulls a partial vacuum on your lungs, causing them to expand FIRST...and THEN the partial vacuum created by your expanded lungs causes air to move into them. When you breath out, it causes the reverse to occur.
What Organs that expand to fill with air?
its is the lungs come to us and get your answer
Moving muscles in order to make air flow into and out of the lungs?
The term for moving muscles in order to make air flow into and out of the lungs is breathing. The main muscle that moves is the diaphragm, which sits just below the lungs and causes air to flow in and out as it contracts and expands.
What happens to the ribs and diaphragm when you breathe in?
The diaphragm goes down, pulling air into the lungs. Your ribs expand, helping your lungs to expand also.
