Interactions WIth Other Systems

The excretory system interacts with the Circulatory system. Blood circulates through the body. Then it passes through one of the kidneys. The water, uric acid, and the urea are removed from the blood. Also most of the water is located back into the system. The kidneys interact with endocrine system because the adrenal glands position on the top of each kidney, and the adrenal gland lets adrenaline into the body. it relates to the digestive system because its need energy to work.
