Diffusion along the (partial) pressure gradient.
The blood gets oxygen in the heart. Once the oxygen has been replenished, the blood is sent back out to the organs.
Oxygen enters the body by being absorbed into the blood (specifically, it is absorbed by red blood cells which contain an oxygen-carrying compound known as hemoglobin) when air is inhaled into the lungs, which have a highly porous, spongy structure which facilitates the exposure of blood to the air.
the right ventricle, ( just to make sure you know, the rights and lefts of the heart are opposites) pumps blood through a valve, and up to the pulmonary vein where it travels to the lungs to be oxygenated by the alveoli, and brought back through the pulmonary artery to were the left atrium and ventricle pump the blood to the aorta, where then is distributed to the brain muscles and body
No. The red blood cells get oxygen at the lungs, not drop off carbon dioxide.
The simplest answer is "arteries," which generally carry oxygen-rich blood from the heart to the body, but the pulmonary veins also carry oxygen-rich blood. The lungs have oxygen that gives oxygen to the cells. Our body is a closed system so the blood never leaves the body system unless we are cut. After the blood has used up all of the oxygen it has the blood is recirculated through the heart and lungs once more! Thus this process goes on and on! An ARTERY carries oxygen rich or oxygenated blood from the heart to the body cells to give oxygen to them. I remember this by: Artery Away Arteries carry oxygen rich blood from the lungs to other parts of the body. Veins return oxygen poor blood to the heart where it gets recirculated through the lungs and then throughout the body again. The arteries.
Oxygen enters the blood in the alveoli of the lungs
Oxygen enters the blood in the alveoli of the lungs
They are called alveoli
Oxygen enters the pulmonary blood in the capillaries of the alveoli -- the air sacs of the lungs.
Oxygen enters the blood from the lungs through the process of gas exchange where it diffuses into the bloodstream from the alveoli. In the lungs, carbon dioxide exits the bloodstream and is expelled from the body through exhalation.
Oxygen enters the blood through the thin walls of the alveoli in the lungs during the process of respiration. This occurs through a process called diffusion, where oxygen moves from an area of high concentration in the alveoli to an area of lower concentration in the blood vessels surrounding the alveoli.
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.
The capillary net rould the alveoli.
Oxygen enters the blood through the process of respiration in the lungs. In the lungs, oxygen diffuses from the alveoli into the blood capillaries surrounding them. It then binds to hemoglobin in red blood cells for transport to tissues throughout the body.
Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
Oxygen enters the blood through the alveoli in the lungs. It diffuses across the thin walls of the alveoli into the surrounding capillaries where it binds to hemoglobin in red blood cells for transportation throughout the body.
