Oxygen is absorbed in the blood stream primarily in the lungs through the process of diffusion. When we breathe in, oxygen from the air enters the lungs and diffuses across the alveoli into the capillaries, where it binds to hemoglobin in red blood cells and is transported throughout the body.
Because by straining your muscles uses up more oxygen out of your blood stream, so you have to breathe harder to get new oxygen in.
Because when mammals breathe (Respiratory) it causes their blood to circulate (Circulatory) ad they need their blood to circulate to live. Hope this was helpful. :)
The person will die if the blood does not circulate. Blood is necessary to supply food and oxygen to the body.
oxygen blood cells and non-oxygen blood cells
The oxygen poor blood (not enough oxygen) goes to the lungs to get more oxygen to turn into oxygen rich blood (has plenty of oxygen)
Oxygen is in the air, and when you breathe in the oxygen gets into your lungs and is absorbed into the red blood cells.
liver
it breathes by its skinnn i am also researchin.. lolz
Gas is exchanged by diffusion. We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale? The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth. In the alveoli, oxygen crosses over into the blood stream and carbon dioxide leaves the blood stream and enters the alveoli to be expelled through the lungs.
your diaphram contracts and you inhale the air then the air goes to your lungs where it goes throughout your blood stream then the old oxygen picks up the carbon and then you exhale the oxygen with the carbon
Oxygen enters the blood stream through the air sacs in you lungs.
