Question

Explain human excretory system.

Answer 1

Heya!!

• Our blood contains both useful and harmful substances by reabsorption and toxic substances by forming urine.

• To purify our blood we have Human excretory system. This is a mechanism to filter our blood.

• This is done by the blood capillaries in our kidneys.

• All the needful substances will be absorbed back into the body and the waste materials will be converted into urine. Urine thus formed will be passed to the urinary bladder via ureter. Through the urinary opening at urethra, urine is excreted.

• If these waste materials will be there in our blood, they will start accumulating in the blood. And a body can't survive until the blood is filtered periodically.

Hope it helps!!
