Question

how kidney functions ?

Answer 1

There are two kidneys, each about the size of a fist, located on either side of the spine at the lowest level of the rib cage. Each kidney contains up to a million functioning units called nephrons. A nephron consists of a filtering unit of tiny blood vessels called a glomerulus attached to a tubule. When blood enters the glomerulus, it is filtered and the remaining fluid then passes along the tubule. In the tubule, chemicals and water are either added to or removed from this filtered fluid according to the body's needs, the final product being the urine we excrete.

The kidneys perform their life-sustaining job of filtering and returning to the bloodstream about 200 quarts of fluid every 24 hours. About two quarts are removed from the body in the form of urine, and about 198 quarts are recovered. The urine we excrete has been stored in the bladder for anywhere from 1 to 8 hours.

=> Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.

=>Regulation of osmolarity. ...

=>Regulation of ion concentrations. ...

=>Regulation of pH. ...

=>Excretion of wastes and toxins. ...

=>Production of hormones.

=>A – controlling ACID-base balance.

=>W – controlling WATER balance.

=>E – maintaining ELECTROLYTE balance.

=>T – removing TOXINS and waste

products from the body.

=>B – controlling BLOOD PRESSURE.

=>E – producing the hormone ERYTHROPOIETIN.

=>D – activating vitamin D.

i hope it helps you.
