Kidney

Kidney (Latin ren, Greek. νεφρός [nephros], English. kidney) is a human organ. An adult has a length of 12 cm, a length of 6 cm, and a length of 3 cm. The kidney is placed on the back wall of the sacral cavity at the 12th vertebra, and its minimum size is at the height of the 3rd dorsal vertebra. It is located 1.5-2.0 cm on the left and right sides. The reason for this is that the right kidney is pressed against the right kidney.

The renal artery, the renal vein, and the ureter are all called the renal sinus. It is at the entrance of the kidney, and the cavity is called the renal pelvis. The renal pelvis collects the urine in the kidney and passes it to the ureter. The renal pelvis collects urine from 2-3 major calyces, and the major calyx collects urine from 2-3 minor calyces. The kidney is covered with fibrous connective tissue. Interstitial tissue of the kidney is a fluffy connective tissue, and on the outside it is rich in reticular and reticular economy. The kidney is divided into two parts: the cortex and the medulla, and the medulla, which is slightly more useful for the cortex, has acquired a pale appearance. The cerebrum is made up of 8-12 pyramidal structures (renal pyramids) with the base of the pyramid facing the cortex and the apex facing the entrance of the kidney. At the top of the pyramid, the tip of the papilla, such as the renal papilla, collects urine through a small cup. Interstitial tissue of the pyramids was deciphered as the renal column (renal column). The functional unit of the kidney is the nephron. Nephrons filter blood and produce urine, and each kidney consists of 1 million good nephrons.

Participates in the formation and excretion of urine.

Regulates cell fluid balance [ECF].

Regulates blood pressure.

Role of electrolyte compensation in body fluids.

Acid-base balance.

Regulates osmotic pressure in plasma.

Regulation of erythropoietin.

Renin-angiotensin, prostaglandin, and kallikrein-kinin apparatuses are involved in the endocrine system of the kidneys.

The key to preventing and slowing down the progression of kidney disease is keeping your blood pressure stable, or more specifically, keeping your blood pressure below 130/80. 3/2 percent of the main causes of chronic kidney disease are diabetes and high blood pressure. That's why it is possible to prevent the disease by following a regular exercise and a healthy and well-balanced diet.
