Document Summary
Exocrine functions of the kidney: exocrine function. To clear the blood of nitrogenous metabolic waste products like urea and ammonia. Secretion of nitrogenous waste and metabolic waste products nephron exocrine function. To help maintain macro- and micromineral homeostasis. Increase in secretion through the nephron, decrease content of these nutrients in the body. Can be reabsorbed from filtrate and back into circulation, increasing the body content of those minerals/ nutrients. To regulate water and salt content of the extracellular body water compartment. Will help long-term control of blood pressure. Low sodium salt diminishes retention of water in kidney, causing blood pressure to be lowered. To help regulate acid-base homeostasis in the body. Kidney is typically set up to secrete hydrogen ion; exchanges hydrogen ion for sodium or potassium ion in the filtrate. Liver also synthesizes and secretes vitamin d: different form the precursor. Endocrine functions of the kidney: endocrine function. Production of 1,25 dihydroxycholecalcifol active vitamin d.
