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.
What else can I help you with?
When your muscles move your ribs to make the lungs bigger and smaller?
breathing ant it
When your muscles move your ribs to make the lungs bigger or smaller?
A misunderstanding. That's not how breathing actually works. Your rib cage is all but immobile.
When you breathe out dose your chest get bigger or smaller?
When you breathe out, your chest gets smaller. This happens because the diaphragm and intercostal muscles relax, allowing the lungs to deflate and air to be expelled from the body. As the lungs contract, the rib cage also moves inward, leading to a decrease in chest volume.
What do the bellows and bladder in Mayow's model represent?
The answers above are wrong The correct answer is: The bellows represent the ribcage/muscles and the bladder represents the lungs. hopefully this helps .
How is Neanderthals different from Con-Magnons?
Shorter, stockier, bigger muscles, expanded ribcage with larger lungs.
What do the Lungs do in the respiratory system?
They get bigger, then smaller. Yup, pretty much. P.S the person who wrote this is stupid...The lungs inflate then deflate XD
What is the movement of the chest that brings air into lungs and takes out waste gases called?
The movement of the chest that brings air into the lungs is called inhalation, and it is facilitated by the contraction of the diaphragm and intercostal muscles. Exhalation is the process of removing waste gases from the lungs, which is typically a passive process where the diaphragm and intercostal muscles relax.
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 process called when the lungs are getting bigger and smaller?
The process of the lungs getting bigger and smaller is called respiration, specifically during inhalation and exhalation. During inhalation, the diaphragm contracts and moves downward, expanding the chest cavity and allowing air to enter the lungs. Conversely, during exhalation, the diaphragm relaxes, the chest cavity decreases in size, and air is expelled from the lungs. This cycle is essential for gas exchange in the body.
What differentiated Homo sapiens from the Neanderthal?
Physically, Neanderthals had a larger body mass, bigger muscles, an expanded ribcage that housed bigger lungs, a weak chin and a prominent brow ridge.
