Answer 1

The conspicuous wrinkles that form on the mucosa of a relaxed bladder are known as rugae. These wrinkles allow for the expansion of the bladder as it fills with urine.

Step-by-step explanation:

When the bladder is relaxed, its mucosa has conspicuous wrinkles called rugae. The bladder is a highly distensible organ, and when it is not full, the transitional epithelium lining the bladder forms wrinkles or rugae. This feature allows for the expansion of the bladder as it fills with urine, without causing damage to the mucosal lining. Rugae flatten out as the bladder stretches with increasing volumes of urine.
