Answered by RionaR

Oxygen-poor blood from your veins is received from the right side of your heart and injected into your lungs, where it takes up oxygen and gets rid of carbon dioxide. Your heart's left side collects oxygen-rich blood from your lungs and pumps it to the rest of your body through your arteries.
