During heart surgery, a heart and lung bypass machine is used so that the heart can be stopped while the procedure is carried out. Blood is taken from the blood vessel that carries it into the heart from the body and diverted through the bypass machine. The machine adds oxygen to the blood and then pumps it back into the blood vessel that carries it away from the heart so it can return to the body. In which blood vessels are the tubes inserted to take blood from the body to the bypass machine and to send the blood back to the body?
