We breath because the oxygen/CO2 levels in our lungs are less than that of our surroundings. When you breathe in, your lungs expand and allow more oxygen to flow in. When you exhale, the CO2 levels in your lungs is greater than the your surroundings, so the CO2 leaves and the process repeats itself. This is called negative pressure breathing.
Air enters our lungs so we can obtain oxygen to fuel our cells in our body.
Air leaves the lungs because when oxygen enters the cells waiting in the lungs, the bi-product the cell makes when it absorbs the oxygen is carbon dioxide, which is exhaled from the lungs.
I think you meant move air into the lungs. The muscle is the diaphragm.
Diaphragm
Lungs Move Oxygen From The Air Into The Blood.
inhale:- the air pressure in the lungs decreases and air moves in. exhale:-air pressure in the lungs increases and air moves out.
When your lungs move to bring in air and remove gases you are breathing.
the expansion and relaxation of your diaphram.
your diafram
it is the muscle that makes your lungs move so you can get air.
Actually, air isn't forced into the lungs my the contraction of any muscle, but by the relaxation of the Diaphragm, along with the Intercostalis muscles on the ribs and the smooth muscle on the lungs. When your diaphragm contracts, it pushes air out of your lungs. When it relaxes, air is drawn in to the lungs. The intercostalis muscles also help move the ribs when the lungs move as your breath. There is one set on the ribs and one set in between each rib.Hope this helps!
the lungs and respiratory system
The muscle is known as the diaphragm.
note when we yarn our lungs contract this is proven because our chest move inward as air is release.
