What is the movement when your muscles move your ribs to make the lungs bigger and smaller?

It is air that does it, as well as the rib muscles themselves. The diaphragm contracts, expanding the internal area of the thoracic (chest) cavity, causing a drop in pressure. Air is then drawn through the nose into the lungs, which expand, causing the ribs to move to accomodate this.

A misunderstanding. That's not how breathing actually works. Your rib cage is all but immobile.

They get bigger, then smaller. Yup, pretty much. P.S the person who wrote this is stupid...The lungs inflate then deflate XD
Why the vital capacity of a marathon runner is greater than the vital capacity of a nonactive people?
If a person exercises a lot, he or she will not only train his or her muscles, but also his or her lungs. And since the lungs are surrounded by muscles, you train these muscles too. So a marathon runner has stronger lungs, that have a bigger capacity, as the muscles that surround can contract and stretch farther than those of a nonactive person.
What are 2 key facts about a neanderthal?
They had bigger muscles than modern humans, and they had an expanded ribcage, which allowed for larger lungs.
Why were neanderthals unique?
They were adapted to cold conditions. Larger mass, bigger muscles, and an expanded rib cage that housed big lungs.
What is the movement of air on and out the lungs?
The movement of air on and out the lungs is called respiration. The movement of air into the lungs is called inhalation (inspiration). The movement of air out of the lungs is called exhalation (expiration).
What differentiated Homo sapiens from the Neanderthal?

When you breathe in do your lungs go up and out?
When you breath, your lungs can go up and out a little, but mostly, your lungs go down. The breathing device is the diaphragm, a sheet of muscles going across your chest inside front to back. As the diaphragm 'bends' itself down, the lungs have to move with it and get bigger. When the lungs get bigger, they have no choice but to suck in more air through the mouth or nose. When the diaphragm 'bends' or moves upward, air is pushed out of the lungs.
Do lungs have musles?
yes because organs are made up of tissues and so are muscles and for the lungs to move they need the muscle. So yes your lungs do have muscles.
