These are the brain, heart, kidneys, liver and lungs. The human brain is the body's control center, receiving and sending signals to other organs through the nervous system and through secreted hormones. ... The kidneys take urea out of the blood and combine it with water and other substances to make urine.
The heart is a muscular pump that with each heart beat pumps blood around the body. On leaving the heart the blood first travels along the arteries. The pulse is what you feel over an artery as the pressure inside increases following each heart beat. The average pulse rate is between 60-80 beats per minute
