Question

Explain the excretory system in humans

Answer 1

Hi Jamesbond1111,
Here's the answer..

The excretory system of human beings includes a pair of kidneys, a pair of ureters,a urinary bladder and a urethra. Kidneys are located on either side of vertebral column. Urine produced in the kidneys passes through the ureters into the urinary bladder where it is stored until it is released through urethra.

Just as carbon dioxide is removed from the blood in the lungs , nitrogenous wastes such as urea are removed from blood in the kidneys. A cluster of very thin walled blood capillaries perform this. each capillary cluster is associated with cup shaped end of a tube that collects filtered urine. Each kidney has large number of these filtration units called nephron.Some substances in initial filtrate such as glucose, amino acids , water are selectively reabsorbed as the urine flows through the tube.

The urine forming in each kidney enters ureter which connects the kidneys with urinary bladder. Urine is stored in urinary bladder until the pressure of the expanded bladder leads to the urge to pass it out through urethra. The bladder is muscular so we can usually control the urge to urinate as a result of nervous control...
