Answer 2

Answer:

Human excretory system consists of a pair of kidneys, a pair of ureters, urinary bladder and urethra.

Explanation:

• The kidneys are the body's principal excretory organs. Kidneys are bean-shaped structures that are protected by the ribs and back muscles on either side of the spine.
• The ureter is a pair of thin muscular tubes that originate out of each kidney and extend from the renal pelvis. Urinary ureters transport urine from the kidneys to the urinary bladder, which stores it. The urethra then excretes the urine.
• A muscular sac-like structure that retains urine is known as the urinary bladder. Micturition, or urinating, is the process by which the urine bladder is emptied.
