Normal renal function and their
Kidneys are bean-shaped organs of a couple who lie on either side of the spine in the lower middle back. Each kidney weighs about a pound and contains about ¼ million units called nephrons filter. Each nephron consists of a glomerulus and tubules. Glomerular filtration is a miniature or screening devices, while the tube is a tiny tube structure glomerulus.
The kidneys are connected to the bladder through tubes called ureters. Urine is stored in the bladder until the bladder is emptied during urination. The bladder is connected with the outside of the body through another tube like structure called the urethra.
The main function of the kidneys is to remove wastes and excess water from the blood. The kidneys process about 200 quarts of blood per day and produce about two liters of urine. The waste products of normal metabolic processes, including distribution of active tissues, including food and other materials prepared. The kidneys can not use different foods, medications, vitamins and nutritional supplements, supplements, and excess fluid is concern that toxic by-products build up to dangerous levels. Kidney also plays an important role in regulating the level of various minerals like calcium, sodium and potassium in the blood.
As a first step in filtering the blood flow into the glomeruli of microscopic blood vessels called capillaries leak delivered. That the blood of toxins and fluid filtered red blood cells, proteins and large molecules are retained in the capillaries. In addition to waste some useful substances are also filtered. The filtrate is collected in a bag called the Bowman's capsule.
The next step in the tube filtration. Tubes are equipped with highly functional cells that lined the process of leachate, mineral water and biodegradable chemicals, the body, while secreting a number of additional waste
in a tube. Kidneys also produce certain hormones that perform important functions in the body, including:
The active form of vitamin D (calcitriol or 1,25 dihydroxy-vitamin D), the absorption of calcium and phosphorus from the diet regulates the establishment of strong bones.
Erythropoietin (EPO) in stimulating bone marrow to produce red blood cells.
