Question

Assertion urinary bladder & ureters are lined by transitions.
epithelium
Reason - ueters carry the urine to urinary bladder where it is
stored temporarily​

Answer 1

Explanation:

Urinary bladder and ureters of excretory system are lined by transitional epithelium because it is a stretchable epithelium, hence the urinary bladder and ureters may be considerably stretched without getting torn when they are filled with urine.

Ureters are thin muscular tubes which emerge from the hilum of each kidney. Urine enters the ureters from the renal pelvis and is conducted along the ureters by peristaltic waves on their walls. Ureters from both the kidneys finally open into urinary bladder which is a hollow muscular sac. In this way urine from both the kidneys is drained into the urinary bladder which stores it temporarily.

So, the correct answer is 'Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion'.
