Question

describe how the human body get rid it's waste through kidney​

Answer 1

Explanation:

There is a special system for excretion of urine of human beings.

The excretory system of human beings consists of a pair of kidneys, a pair of ureters, a urinary bladder and a urethra. (See in the above figure).

• The urine is formed by filtering out the nitrogenous waste present in the blood.
• Inside a kidney, many very thin - walled blood capillaries are present. Each capillary is connected with a cup - shaped end of a coiled tube called Bowman's capsule that collects the filtrate.
• The Bowman's capsule further passes the filtrate towards a long tube called Henle's loop for the reabsorbtion of some materials like glucose, amino acids, salts, water.
• The urine formed in each kidney enters a long tube called the ureter through the collecting duct.
• Urine is stored in the urinary bladder until it gets the required pressure to pass it out through urethra.

The long extended tube where blue and red capillaries are attached together is called as Henle's loop. (Not a defination, just for understanding!)
