How does water maintain human balance?

Normal people's daily water source and discharge are in a state of dynamic balance, and the daily water source and discharge are maintained at about 2500ml. The sources of water in the body include drinking water about 1200ml, food water about 1000ml and endogenous water about 300ml.

The water in the body is mainly excreted through the kidney, accounting for about 60%, followed by the lungs, skin and feces, with a total excretion of about 2500ml. The normal balance of water in the body is regulated by vasopressin secreted by thirst center, pituitary gland and kidney.

The human body can maintain the balance of water in the body by adjusting the amount of urine. Too much water in the human body will weaken the reabsorption of water by renal tubules and collecting pipes, that is, the urine volume will increase, the water in the human body will be insufficient, the reabsorption of water by renal tubules and collecting pipes will increase, and urination will decrease. But it can only be adjusted within a certain range.
