In regard to blood circulation, if you begin with oxygen-poor blood that reaches the heart from the body and is pumped through arteries to capillaries of the lungs, then determine the order for the following: 1. In capillaries of the body, nutrients and oxygen move from the blood to body tissues. 2. Oxygen-rich blood returns to the heart from the lungs by veins. 3. In capillaries of the lungs, oxygen from inhaled air is picked up by the blood and carbon dioxide is released into the lungs and exhaled. 4. Oxygen-rich blood is pumped out of the heart into arteries leading to the body.
