oxygen rich blood gets pumped out of your heart to your arteries which carries the blood to your muscles. then your muscles use the oxygen. oxygen poor blood goes into your veins to go back into your heart. then it goes through a cycle that takes your blood to your lungs, to get oxygen. this process is repeated.
red blood is oxegenated; it has oxygen in it blood blood is not oxygenated; it does not have oxygen in it Arteries have red blood in them; they go to muscles so the muscles can use the oxygen, Veins have blue blood in them; they go back to the heart to go to the lungs to get oxygen when you get cut, even in a vein, the blood is red because when the blood comes out it becomes oxygenated. Although, when an artery gets gut it is bright red, although when a vein gets cut it is dark red. JACOB PONTOW IS A BEAST ^ who the heck is he?
Gas exchange occurs in the vessels of the lungs
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 makes blood red go read a science book
After the lungs the blood goes to the heart. The heart then pumps the blood around the body via the arteries to where the oxygen is needed. The veins return the blood, with oxtgen removed, to the lungs where it can be oxygenated again.
When it is rich with oxygen. It will become dark colour when it contain less oxygen (after the oxygen used by the body tissues )
Yes, the blood from the lungs is rich in oxygen. Since you breathe in oxygen and nutrients through your nose/mouth to the lungs, the oxygen and nutrients are absorbed in the lungs and go through the blood stream into the heart
