Oxygen in the alveoli is picked up by hemoglobin in erythrocytes (red blood cells) in the capillaries of an alveolus. The erythrocytes then travel back to the heart through the pulmonary vein and gets pumped to the rest of the body through the left atrium, left ventricle, and the aorta.
It sends oxygen to individual alveoli in your lungs, which sends oxygen to your body's cells.
When oxygen reaches the alveoli in the lungs, it diffuses from the air in the alveoli into the surrounding capillaries. The oxygen then binds to hemoglobin in red blood cells, which transports it to the body's tissues for use in cellular respiration.
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 enters your body through the lungs when you breathe. In the lungs, oxygen moves into the bloodstream through tiny blood vessels called capillaries. From there, oxygen is carried by red blood cells to tissues and organs throughout the body.
Oxygen diffuses from the alveoli into the capillaries, where it binds to hemoglobin in red blood cells for transport to tissues. Carbon dioxide diffuses from the capillaries into the alveoli and is exhaled from the body.
Oxygen diffuses into the blood from the alveoli in the lungs during the process of respiration. This occurs due to the difference in oxygen concentration between the alveoli and the blood in the capillaries surrounding them. The oxygen then binds to hemoglobin in red blood cells for transport to tissues and cells throughout the body.
Oxygen diffuses through the alveoli in the lungs into the blood stream. Here, haemoglobin bonds with the oxygen, forming oxy-haemoglobin. When needed, the oxy-haemoglobin breaks down to form oxygen and haemoglobin to unload the oxygen into nearby cells.
When oxygen is inhaled, it passes through the nose or mouth, travels down the trachea, enters the lungs, and eventually reaches the alveoli. In the alveoli, oxygen diffuses into the bloodstream, where it binds to hemoglobin in red blood cells. These oxygen-loaded red blood cells then circulate throughout the body, delivering oxygen to cells and tissues for cellular respiration.
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Oxygen is picked up in the lungs when you inhale air. The oxygen is then transported from the lungs to the rest of the body by red blood cells in the circulatory system.
Oxygen is transferred to blood cells in the capillaries around the alveoli. It diffuses from the alveoli into the bloodstream, and to the hemoglobin molecule.
Oxygen diffuses from the alveoli into the blood due to higher PO2 (partial pressure of oxygen) levels in the alveoli than in the blood.
