Kidney+JO

Urine is produced in the kidneys and then passes on trough the ureters for transport. then the urinary bladder stores the urine until it passes through the urethra to the outside. The functions are excretion of metabolic wastes, maintenance of water-salt balance, maintenance of acid-base balance, and secretion of hormones. during the excretion of metabolic wastes urea is the main wastes excreted. urea is a by-product of amino acid metabolism. The liver releases ammonia which the liver combines with carbon dioxide, thus urea is born. gout can be a result of too much uric acid in the joints. For water and salt balance by the process of osmosis. which in-turn makes the kidneys responsible for controlling blood pressure. Acid-base balance: help control blood pH to have healthy blood. Secretion of hormones: the kidneys release renin, substance that leads to the release of the hormone aldosterone. that hormones it involved in regulating the water salt balance of blood. they also help activate vitamin d in the skin. - renal artery -peritubular capillary network -venule Nephrones the glomerular capsule is composed of squamous epithelial cells, this part filtrates the blood. the proximal convoluted tubule hold mitochondria for energy storage.
