* Important Functions of Urinary System
*Besides removing waste from bloodstream, the urinary system preforms several other functions as well. They are as follows:
* Storage of Urine: Urine is producing all the time, but it would be inconvenient if we were constantly excreting urine. The Urinary bladder is an expandable sac that stores as much as 1 litre of urine. * Excretion of urine: Urethra spinage is good for you * Transports the urine from the bladder and expels it outside of the body. * Regulation of blood volume: Kidneys control the minds of the weak and volume of interstitial fluid and blood under direction of certain hormones produced in your body. Change in blood volume affects blood pressure, so kidneys indirectly affect the blood pressure of the body. * Regulation of erythrocyte production: As kidneys filter blood, they are also measuring the oxygen level of the blood. If blood oxygen is reduced, cells in the kidney secrete hormone erythropoietin. Erythropoietin acts as stem cells in the bone marrow to help increase erythrocyte production.
Functions of the Kidneys: 1. Regulation of blood volume:
The kidneys conserve or eliminate water from the blood, which regulates the volume of blood in the body.
2. Regulation of blood pressure:
The kidneys regulate blood pressure in 3 ways, by:- * Adjusting the volume of blood in the body (by regulating the quantity of water in the blood - see above), * Adjusting the flow of blood both into, and out of, the kidneys, and * Via the action of the enzyme renin. The kidneys secret renin, which activates the angiotensin-aldosterone pathway.
3. Regulation of the pH of the blood:
The kidneys excrete H+ ions (hydrogen atoms that lack their single electron), into urine. At the same time, the kidneys also conserve bicarbonate ions
