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.
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.)
Gases move in and out of the blood through diffusion. Oxygen from the alveoli in the lungs diffuses into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. This process is crucial for gas exchange and maintaining the body's pH balance.
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.
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.
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.
Oxygen in & carbon dioxide out. The change occurs within the cells and blood carries the gasses between the lungs and the cells.
lungs remove CO2 and other unessential gasses from the blood, and adds oxygen to the body (the essential to life) and the heart pumps the blood full of oxygen through the body to the body cab use the oxygen. and it pumps the CO2 full blood to the lungs to dispel it from the body.
The blood carries them to all parts of the body
---------------------------- The exchange of gasses takes place across the Alveoli, which are air spaces surrounded by very small air sacs and have a rich supply of blood, because they are surrounded by capillaries. The lungs are made up of many alveoli which are the respiratory surface. Oxygen diffuses from the alveoli into the blood in the capillaries and carbon dioxide diffuses from the blood in the capillaries into the alveoli.
