उत्तर
Human beings have a urinary system to eliminate nitrogenous waste products. It consists of:
- Kidneys: These are a pair of reddish-brown, bean-shaped structures that lie on either side of the backbone. They filter the impure blood and produce urine.
- Ureters: A pair of ureters are tubes that lead out from each kidney. These tubes carry urine from the kidneys to the urinary bladder.
- Urinary bladder: It is a pouch-like muscular structure in which urine is stored temporarily.
- Urethra: It is a canal-like opening at the bottom of the urinary bladder through which urine is passed out.
