The Functions of the Urinary System Filter the blood to remove waste products product from the body (mainly urea and uric acid). Regulation of acid-base homeostasis Controlling blood volume and maintaining blood pressure Regulation of electrolyte balance (e.g. sodium, potassium and calcium)
The structures of the urinary system The urinary system is consists of four main parts: Kidneys Ureters Bladder Urethra
The structures of the Kidneys: Each kidney consists of two layers that surround the renal pelvis. 1.The cortex: is the outer layer of the kidney. It contains over one million microscopic unit called nephron. 2. The medulla :is the inner one, it contains most of the urine collecting tubules. Nephrones: are the functional units of kidneys. They form urine by the process of filtrations re- absorption and secretion.
The structures of the urinary system The ureters: they are narrow tubes, each about 10-12 Cm long. Each ureter carries urine from a kidney to the urinary bladder. The Bladder : It is a hollow muscular organ that is a reservoir for urine. The urethra : it is the tube extending from the bladder to the out side of the body. The urethral meatus : it is the external opening of the urethra.
Medical specialties related to urinary system Urologist : Specializes in diagnosis and treating diseases and disorders of the kidney.
