The main role of kidney is to excrete metabolic products, regulate acid-base balance and water-electrolyte balance, in addition to certain endocrine function, which is important for the stability of the body’s internal environment.
1. The main function of kidneys is to filter all kinds of metabolic wastes in the body, such as urea, creatinine, uric acid and other medium and large molecule toxins, to maintain the balance of the internal environment.
2. Regulation of acid-base balance and water-electrolyte balance: the kidneys can maintain the acid-base balance and water-electrolyte balance in the body through the excretion of hydrogen ions, reabsorption of bicarbonate, and the excretion of water and excess electrolytes, which can keep the ions in dynamic balance.
3. Endocrine function: the kidney is not only an excretory organ, but also secretes a lot of hormones and degrades many peptide hormones; vasoactive substances, erythropoietin and vitamin D3 are mainly produced by the kidney, and the kidney is also the organ of endocrine hormones such as parathyroid hormone, calcitonin, etc., which has a certain feedback effect.
