All of them
The process of simple diffusion. Oxygen moves from the alveoli into the blood where it binds to hemoglobin in red blood cells, while carbon dioxide moves from the blood into the alveoli to be exhaled out of the body.
oxygen and carbon dioxide
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
In the capillaries surrounding the alveoli in the lungs
Alveoli absorb oxygen through a process called diffusion, where oxygen in the air within the alveoli moves into the blood in the surrounding capillaries. The thin walls of the alveoli and capillaries facilitate this exchange, allowing oxygen to pass from an area of higher concentration (inside the alveoli) to an area of lower concentration (the blood). Simultaneously, carbon dioxide moves from the blood into the alveoli to be exhaled. This efficient gas exchange is essential for maintaining oxygen levels in the body.
Basiclly,The air enters the lungs by traveling down the wind pipe and it goes down the bronchi and bronchioles and into the alveoli.The Alveoli let the oxygen (from the air) pass into the blood streem by leting it pass through a thin membrane.
Oxygen is able to pass into your blood through diffusion. In the lungs, oxygen moves from the alveoli in the lungs into the surrounding capillaries where it binds to hemoglobin in red blood cells for transport throughout the body.
The oxygen in each breath is circuited to the lungs where the alveoli absorb the oxygen and passed to the blood cells. The blood cells enter the heart where the oxygenated blood is circulated where needed.
Oxygen passes into the blood from diffusion in the alveoli of the lungs.If you're asking where blood is made, it's made in bone marrow.
You breathe the oxygen into your lungs. The oxygen then dissolves into the water lining which is called the alveoli. Finally, the oxygen will cling to the red blood cells as they pass through the alveolar capillaries and now the oxygen is in the blood.
Alveoli are the tiny air sac structures in the lungs where gas exchange occurs. Their thin walls allow oxygen to pass into the bloodstream and carbon dioxide to be removed. This makes alveoli a critical component of the air-blood barrier, facilitating efficient exchange of gases between the lungs and the blood.
the lungs supply the blood with oxygen, within the lungs there are alveoli which have a very thin membrane which allows oxygen to pass into the capillaries that run into the lungs hope i helped
