WebRed blood cells have the important job of carrying oxygen all over the body. These cells, which float in your blood, begin their journey in the lungs, where they pick up oxygen from the air you breathe. Then they travel to the heart, which pumps out the blood, delivering oxygen to all parts of your body. WebOrganisms that are active have evolved a closed circulatory system in which blood is kept within the vessels all the way through the circuit. Mammals blood loses its pressure as it passes through the lungs therefore, returns …
