The blood is oxygenated that is oxygen which has been inhaled is added to the blood and the blood then transports it to other body parts.
Gases are exchanged. Oxygen is exchanged for carbon dioxide in the red blood cells.
you breathe out xx
The red blood cells pick it up from the air and take it through the blood stream to the cells in the body.
bye- bye!!
bicarbonate and oxygen
When air reaches lungs which has thousands small sacks called alveoli the oxygen is difussed to blood capillaries that line alveolar wall.
the kidneys clean it by removing the waste from the blood
It turns red
it evaporates when you breath out (exhale)
You die, I mean you're bleeding into your lungs.
When blood is pumped into the thin-walled blood vessels of the lungs, carbon dioxide is replaced with oxygen.
Blood changes color at the lungs because it unloads carbon dioxide and absorbs oxygen. Red blood cells that are carrying oxygen are a brighter red color than red blood cells that are depleted of oxygen.
