Air (about 20% oxygen) is inhaled and filtered through the nose. Then it passes through the trachea, bronchi, and the bronchioles. There are only two main bronchi that lead into many bronchioles of decreasing size. The smallest of these open up into sac-like structures in the lungs called the alveoli. The alveoli are surrounded by capillaries, from which the oxygen diffuses into the blood stream and the carbon dioxide diffuses out. Then, the oxygen-depleted, and carbon dioxide-rich, air is exhaled out by the same route, but in the opposite direction.
What else can I help you with?
What muscles move the air in and out of the lungs?
I think you meant move air into the lungs. The muscle is 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.
Which is the movement of the chest that brings air into the lungs and removes waste gases?
When your lungs move to bring in air and remove gases you are breathing.
What causes air to move in and out of your lungs?
the expansion and relaxation of your diaphram.
What is a frozen diaphragm?
it is the muscle that makes your lungs move so you can get air.
What causes air to move into and out of a person lungs?
your diafram
What is able to move up and down for moving air in and out of lungs?
The diaphragm and intercostal muscles contract and relax to create changes in lung volume, allowing air to move in and out of the lungs through the trachea. This process is known as breathing or respiration.
Air is forced into the lungs by the contraction of the?
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!
What happen to the lungs when you yarn?
note when we yarn our lungs contract this is proven because our chest move inward as air is release.
What are the Muscles beneath lungs that helps air move in and out?
The muscle is known as the diaphragm.
What does the human diaphragm do?
It contracts and relaxes to help pull air into the lungs and push it back out. The diaphragm contracts and moves lower which expands the ribs and allows air to move into the lungs. When it relaxes, the ribs contract and push air back out of the lungs.
How do the lungs move?
The diaphragm is a strong wall of muscle on the bottom of the chest cavity. As this wall of muscle expands downward, a vacuum is created which pulls air into the lungs. As the diaphragm returns to it's original position, air is pushed out of the lungs.
