gas exchange occurs in the alveoli in the lungs where deoxygenated blood gets oxygen, that blood then goes to the heart and is pumped through the body through the aorta and the arteries, which brings oxygen to the body cells.
Via diffusion from the alveoli to the capillaries surrounding them
Oxygen is the gas that passes from the lungs to the bloodstream.
The circulatory system (blood) transfers all nutrients and gases (oxygen and Carbon Dioxide) to all parts of the body
Carbon dioxide, or CO2
Looks like a bubble in the lungs; its function is to exchange gasses between the air inhaled and the blood flowing through the lungs. (Mostly oxygen into blood and CO2 out of the blood.)
It's not so much that the lungs need alot of blood, but more that the blood depends on the lungs. The nature of the lungs allows the blood to pick up and carry oxogen to the rest of the body and the very thin membranes of the lungs allow the exchange of gasses, oxygen into the blood and carbon dioxide out of the blood.
The partial pressures of each of the gasses, as present in the blood and in the alveoli.
gas exchange takes place in the lungs, and at the cellular level. In the lungs, carbon dioxide and other "waste" gasses are released from the blood to be exhaled, and oxygen is absorbed into the blood. At the cellular level, oxygen is released from the blood into a cell, and carbon dioxide and other "waste" gasses are passed into the blood.
From your lungs the air is taken up by your bloodstream which distributes it to the cells in your body. the blood then takes unwanted gasses back to your lungs which you exhale.
Lungs Move Oxygen From The Air Into The Blood.
It is because your body requires a lot of surface area for diffusion of gasses into the blood.
They are the alveoli.
the blood goes to the pulmonary artery and then goes into the lungs.
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
