Hormones released by the system regulate the amount of urine produced by the system

endocrine and excretory

Different glands in the endocrine system (ex: the adrenal gland) produce hormones (ex: epinephrine/adrenaline) that circulate throughout the blood to regulate various cellular processes in various areas of the body.

The excretory system is responsible for the excretion of wastes from the body. This body system includes several organs from other body systems. For instance, the lungs are technically a part of this organ system (along with the respiratory system) because the lungs remove CO2 (a metabolic waste product from cellular respiration) from the blood and out of the body when you breathe out. Another, probably even more obvious example, of organs involved in the excretory system are the kidneys, bladder...etc (i.e. urinary system).
