Water-salt homeostasis of the human body and electrolytic composition of the internal liquid environment

Maintaining water and salt balance in the body is important for the basic functioning of cells. It reduces the water level by increasing the urine production of the kidneys. During excessive salt intake, the blood absorbs water from the tissues and edema occurs. To prevent this, the kidneys increase the amount of urine. Excess salt is excreted in the urine. Blood pressure regulation is one of the most complex aspects of homeostasis. The adrenal glands, spine, and sympathetic and parasympathetic nervous systems work together to balance blood pressure and keep it at a healthy level. Changes in blood pressure are detected by receptors and the information is sent to the brain for processing. Blood pressure either rises or falls with the help of nerve impulses and hormones to the heart.
