A tadpole's circulatory system has one loop and a 2 chamber heart. Oxygen-poor blood goes to the heart from the blood vessels in the body. Then the oxygen-poor blood goes up from the heart through blood vessels in the lungs. Next it comes out as oxygen-rich blood and goes back to the heart. Finally the oxygen-rich blood goes into the blood vessels in the body.
The person will die if the blood does not circulate. Blood is necessary to supply food and oxygen to the body.
