a artery actually move the blood to your lung but th perodic vane helps like a police officer to stop and move the blood
the structure is the alveoli in the lungs. they look like bubbles in the lungs.
veins
Alveoli
Oxygen moves through your red blood cells.
the oxygen releases carbon dioxide
the oxygen releases carbon dioxide
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.
through respiratory membrane via diffusion
The cell membrane simply accepts it when it is delivered through the blood.
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)
The circulatory system (blood) moves oxygen through the body to the cells.
Oxygen is brought into the blood stream by inhalation. Carbon dioxide moves out of the cells, into the blood, and taken to the lungs to be exhaled. Oxygen in, carbon dioxide out.
Oxygen
Red blood cells contain a chemical called hemoglobin which has the capacity to form a weak bond to oxygen molecules, so that the oxygen will be carried along, through the blood, by the hemoglobin, but will still be released by the hemoglobin later on, and will therefore be able to reach the various cells of the body, all of which need oxygen in order to metabolize food and generate chemical energy with which to function.
