GENERAL HISTOLOGY

Detailed explanation-1: -After the body has taken the food components that it needs, waste products are left behind in the bowel and in the blood. The kidney and urinary systems help the body to get rid of liquid waste called urea. They also help to keep chemicals (such as potassium and sodium) and water in balance.

Detailed explanation-2: -The kidney excretes toxins through essentially 3 mechanisms: (1) filtration through the glomeruli; (2) passive diffusion, typically from the distal tubules; and (3) active processes where the toxins are transported from the blood as well as into the urine.

Detailed explanation-3: -How does the urinary system work? The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.

Detailed explanation-4: -Healthy kidneys filter about a half cup of blood every minute, removing wastes and extra water to make urine. The urine flows from the kidneys to the bladder through two thin tubes of muscle called ureters, one on each side of your bladder.

Detailed explanation-5: -The process of removal of urine from the bladder through the urethra is called micturition or urination.
