Kidney Disorders
The kidneys are excretory oragans of vertebrates. Together with urinary, the kidneys are organs that filter wastes (such as urea) from the blood and excrete them, along with water, as urine.
In humans, the kidneys are located in the posterior part of the abdomen. There is one on each side of the spine; the right kidney sits just below the liver, the left below the diaphragm and adjacent to the spleen. Above each kidney is an adrenal gland (also called the suprarenal gland).
| Functions |
- Excretion of waste products: The kidneys excrete a variety of waste products produced by metabolism, including the nitrogenous wastes: urea (from protein catabolism) and uric acid (from nucleic acid metabolism) and water.
- Homeostasis: the kidney is one of the major organs involved in whole-body homeostasis. Among its homeostatic functions, there are acid-base balance (regulate the pH), blood pressure balance, and plasma volume balance actions
- Hormone secretion: the kidneys secrete a variety of hormones, including erythropoietin, urodilatin, renin and vitamin D.
