What is 6 Most Important function of Kidney. |
- The Six Main Functions Of Kidney For Our Healthy Lifeline.
- Excretion of Waste.
The Kidney excrete a variety of Waste products produced by metabolism. These include the nitrogenous wastes called " Urea " , from protein catabolism, as well as uric, from nucleic acid metabolism. Formation of urine is also the function of the kidney.
- Reabsorption of vital nutrients.
Glucose at normal plasma levels is completely reabsorbed in the proximal tubule. The mechanism for this is the Na+ / glucose cotransporter. A plasma level of 350 mg / dL. will fully saturate the transportation and glucose will be lost in the urine. Amino acids are reabsorption by sodium dependent transporters in the proximal tubule.
- Acid - Base balance ( Hemostasis )
Two organs systems, the kidneys and lungs, maintain acid - base homeostasis, which is the maintenance of pH around a relatively stable value. The lungs contribute to acid-base homeostasis by regulating carbon dioxide ( CO2 ) concentrations. The Kidneys have two very important roles in maintaining the Acid-base balance: to reabsorb bicarbonate from urine, and to excrete hydrogen ions into urine.
- Osmolality Regulation.
Any sig8rise jn plasma osmolality is detected by the hypothalamus, which communicates directly with the posterior pituitary gland. An increase in osmolality causes the gland to secrete anti diuretic hormone (AHD), resulting in water reabsorption by the kidneys and an increase concentration.
- Blood Pressure Regulation.
The Kidneys secrete Renin. Renin is the first in a series of important chemical messengers that make up the renin-angiotensin system. Changes in eenin ultimately alter the output of this system, principally the hormone antiotensin II and aldosterone. Each hormone acts via multiple mechanisms, but both increase the Kidney's absorption of pressure. When renin levels are elevated, the concentration of angiotensin II and aldosterone increase, leading to increase in blood pressure. Conversely, when renin levels are low, angiotensin II and aldosterone levels decrease, contracting the extracellular fluid compartments, and decreasing blood pressure.
- Hormone Secretion.
Kidneys secrete Erythropoietin and Calcitrol.
Kidney convert vitamin D into Calcitrol helps absorption of calcium at intestines. Erythropoietin helps in production of RBCs in presence of Iron.
