Urine Formation and Separation

Urine Formation and Seperation:

  • Glomerular Filteration:
    • produces cell and protien free filtrate (blood plasma without protiens)

  • Tublar Reabsorption: 
    •  Returns 99% of substances from filtrateto blood by the renal tubules and collecting duct

  • Secretion:
    • Moves substances from blood to filterate in renal tubules and collecting ducts 

  • Excretion:
    • process of seperating wastes from wastes from body fluids and taking them away

The antidiuretic hormone (ADH) regulates urine volume and concentration

Nephron Anatomy and Function

Image
The function of the nephron is to separate water, ions, and small molecules from the blood, filter out toxins and wastes, and return needed molecules to the blood. The nephron functions through ultrafiltration. Each nephron consists of one main interlobular artery feeding a single renal tubule.  The cells in each nephron are arranged so that the most concentrated cells are at the bottom of the nephron, while the cells at the top are less concentrated.

Ureters, Urinary Bladder, and Urethra Anatomy

Ureters: Tube like structures that connect the kidneys with the urinary bladder 25-30 cm long and 3-4 mm wide Paired with kidneys (1 ureter with 1 kidney) Lined with transitional epithelium and smooth muscle Transports urine from kidneys to urinary bladder Urinary Bladder: A hollow, stretchy, muscular organ  Collects urine Lined with transitional epithelium and smooth muscle  Urine leaves the bladder by the internal urethral sphincter into the urethra Urethra: Tube that connects the urinary bladder to the external urethral orifice  In males the urethra is approximately 20 cm long and in women it is 4.8 cm long In males it carries semen and urine while in women it only carries urine  Also lined with transitional epithelium and smooth muscle
