II. Our body needs to remove the wastes that build up from cell activities and from digestion . If these wastes are not removed , then our cells can stop working and we can get very sick.The organs of excretory system consists of a pair of kidneys, a pair of ureters , a urinary bladder and a urethra.Each kidney is made up of nearly one million complex tubular structures called nephrons. The formation of urine involves various processes that takes place in the different parts of the nephrons. Each nephron consists of a cup- shaped upper end called Bowman’s capsule containing a bunch of capillaries called glomerulus. Bowman’s capsule leads to tubular structure,proximal convoluted tubule,loop of Henle and distal convoluted tubule which ultimately joins the collecting tubule.

Question. The out line of principal events of urination is given below in random order.
I) stretch receptors on the wall of urinary bladder send signals to the CNS.
II) The bladder fills with urine and become distended.
III) Micturition
IV) CNS passes on motor messages to initiate the contraction of smooth muscles of bladder and simultaneous relaxation of urethral sphincter. The correct sequence of the events is
A. I → II → III→ IV
B. IV → III → II→ I
C. II → I→ IV → III
D. III → II→ I→ IV

Answer: C

Question. Urine formation occurs through
A. Ultrafiltration,reabsorption,secretion and osmosis.
