Explanation:
Urinary system consist of kidneys, bladder and a ducts that deliver urine out of the body. When you drink much water, the urinary system will remove wastes and adjust the solute composition in the body.
Digestive system takes in food, breaks it down, and delivers nutrients to the blood an eliminates undigested waste. You need to eat more food to digest by the digestive system so you can have more energy to run 5km
Respiratory system includes lungs and the airways. It delivers oxygen from the air to the blood and expels carbon dioxide from the blood into the air. Your breath gets faster and faster because your body uses more oxygen and produces more carbon dioxide.
Nervous system consist of nerves. When you stub your toe, the nerves in your feet will send a signal to your brain and your brain will send a reply that becomes your reaction.
Circulatory system consist of heart, blood and blood vessels. During exercise, your body may need three or four times your normal cardiac output, because your muscles need more oxygen when you exert yourself. Also, your heart typically beats faster so that more blood gets out to your body.
