The farther away you move from the heart, speed slows. The arteries narrow, eventually branching into arterioles. (smallest artery). The blood vessels are so tiny that you and the other red blood cells have to squeeze through in single file. These are the capillaries.
In the capillary you give up the oxygen molecule you've been carrying since the trip from the lungs. The oxygen moves out through the capillary walls and enters the cells of your big toe. There, the oxygen is used to release energy from food. That energy keeps the cells of your big toe alive. After oxygen is released a molecule of carbon dioxide is received, a waste product created from the energy releasing activities of those same toe cells.
The respiratory system draws oxygen into the lungs. The circulatory system moves blood into the lungs to pick up the oxygen and then brings the oxygen to cells in the rest of the body.
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 lungs are the primary organs that fill blood with oxygen. Oxygen from the air is inhaled into the lungs, where it moves into the bloodstream through tiny blood vessels called capillaries surrounding the lungs' air sacs.
Oxygen moves through the body via the bloodstream, carried by red blood cells. It is inhaled into the lungs, where it diffuses from the alveoli into the bloodstream, and then transported to tissues and organs where it is exchanged for carbon dioxide to be exhaled.
Inside the red blood cells, the iron has a great affinity for oxygen. It moves by passive diffusion from the alveoli in the lungs into the bloodstream where it binds to the iron groups in the haemoglobin in the red blood cells.
The oxygen molecules enter the bloodstream by diffusing through the thin walls of the capillaries that surround the air sacs in the lungs. These capillaries are where the exchange of gases like oxygen and carbon dioxide occurs. The oxygen molecules bind to hemoglobin in red blood cells, and are then transported throughout the body to cells and tissues that need oxygen for energy production.
This process is called gas exchange. In the lungs, oxygen enters the bloodstream through diffusion across the alveolar membrane, where it binds to hemoglobin in red blood cells for transportation to tissues.
Yes. This what happens. The oxygenated blood goes to the heart and is pumped out via arteries and end up in the capillaries where the oxygen is exchanged with carbon dioxide and it moves into the body cells.
+++Osmosis
blood flows through your body through the pumping of your heart. however on your red blood cells are hemoglobin which holds oxygen.when your blood cells go through your cells...the hemoglobin picks up the oxygen poor blood and deposits it at your lungs (to be realeased thru exhaling) and get oxygen rich blood (from inhaling)
Oxygen moves from the lungs to the blood through a process called diffusion. This occurs at the alveoli in the lungs, where oxygen in the air sacs diffuses across the alveolar membrane into the capillaries surrounding the alveoli. From there, the oxygen binds to hemoglobin in red blood cells for transport to the body's tissues.
A protein called hemoglobin present in red blood cells is able to bind oxygen molecules. Capillaries surround the alveolar sacs in the lungs where oxygen diffuses into the blood where it is bound by hemoglobin. Now, the oxygen is in the blood.
