Characteristics of kidneys
The kidney is an organ in the urinary system, the main secretion of the urinary system in the body. The position of the kidney is close to the posterior wall of the abdomen, on both sides of the spine near the main lumbar muscle. Both sides of the kidney are horizontal horizontal chest (T12) to burn L3 lumbar in rib cage. The right kidney is slightly lower than the left kidney about 1 vertebra.
The kidney is shaped like a light brown bean, the front is smooth and the back is rough, has a convex shore, a concave shore. Each kidney is about 10 – 12.5 cm long, 5-6 cm wide, 3–4 cm thick and weighs about 170 g.

The structure and function of the kidneys
The structure of the kidney includes: in the center of the inner curve is the umbilical cord, there are ureters, nerves and blood vessels; the outer region is a dark red shell due to many capillaries, about 7-10mm thick; The next part is the medulla and renal pelvis containing fat tissue, blood vessels and nerves.
Each human kidney is made up of 1.2 million kidney units (nephron). This is both a structural unit and a functional unit of the kidney. Each unit of kidney function includes glomerular and renal tubules.
The structure of the kidneys in the body
The glomerulus includes Malpighi bridge and Bowman capsule. Bowman is a bag that covers the bridge, the capsule has many small holes. The Malpighi Bridge has a spherical mass formed from about 50 parallel capillaries. Separating between cysts and capillaries is a thin membrane, which filters the substances from capillaries to follicles.
Each human kidney is made up of 1.2 million kidney units (nephron).
The renal tubules include distal tubule, proximal tubule and Henle loop. Filter from the capsule into the proximal tubule, then go to the Henle loop. At the top of the Henle loop with the distal tubule, from the distal tubule the filtrate is poured into the manifold. The collecting tubule does not belong to the kidney unit, it functions to receive the filtrate from some nephrons to fill the renal pelvis.
The main function of the kidneys is to filter blood and waste. The kidneys filter waste products only between proteins and blood cells. The waste is released, into the filtrate to form urine.
Function of regulating blood volume: The kidney has an important role in controlling the volume of extracellular fluid in the body by producing urine. When we drink a lot of water, the amount of urine will increase and vice versa.
The kidneys help dissolve blood soluble substances, the pH of extracellular fluid and the synthesis of cheek cells: the kidney helps regulate the concentration of ions in the blood. In addition, through the synthesis of vitamin D to help control the amount of calcium icon in the blood.
The meaning and role of kidneys
Based on the content of kidney structure and function above, it is possible to see that kidney has a very important role and meaning to life, eliminating residues and toxins from the human body. . If the kidney is healthy, it will help people excrete a lot of waste from the body and vice versa, if the kidney does not do its job well, the scum will not eradicate but leave the body.
