Draw a well-labelled diagram of a human excretory system. Write the functions of
(a) Kidney
(b) Ureter
(c) Urinary bladder

(a) Kidney- Kidneys filter the blood and remove nitrogenous wastes and other toxic substances from the blood and help in urine formation.
(b) Ureter- The ureters are the tubes that carry urine from kidneys to the urinary bladder.
(c) Urinary bladder- It is the reservoir of urine and stores urine until it is excreted out.
