It's absorbed into the bloodstream.
Yes, when we breathe in, oxygen from the air enters our lungs. This oxygen is then absorbed into the bloodstream through tiny air sacs in the lungs called alveoli.
the oxygen goes to the air sacs inside of the lungs.
Absolutly nothing. Air TRAVELS to your lungs. Nothing makes it go to your lungs.
The air we breathe is mainly composed of oxygen and nitrogen. When we inhale, our lungs absorb the oxygen into the bloodstream for our cells to use, and then we exhale the unused oxygen along with carbon dioxide. The air we breathe eventually gets exhaled back into the atmosphere.
When your blood cells go to your lungs to get oxygen, they also release carbon to make room for the oxygen, then when you breath out, the carbon gets into the air.
The lungs.
into our lungs
No. The circulatory system does transport various gasses around the body but the main gas the body needs is Oxygen (and not 'fresh air'). The blood transports breathed in Oxygen from the lungs into the tissues and organs and transports waste gasses such as carbon dioxide from the tissues and organs to the lungs to be expelled when breathing out. The circulatory system's job is transportation of the gasses to and from where they need to go in the body.
As you go higher in the air, the air pressure decreases, resulting in less oxygen available per breath. This makes it harder for your lungs to extract enough oxygen for your body's needs, leading to difficulty in breathing.
After entering the nose or mouth, oxygen travels down the windpipe (trachea) and then into the lungs. In the lungs, oxygen is exchanged for carbon dioxide in the alveoli, small air sacs where oxygen is taken up by red blood cells and transported to the rest of the body.
to receive oxygen
cuz you suck in
