AIts capacity rises as the uterus lifts away
BIts capacity falls as the uterus compresses it
CIts wall becomes skeletal muscle temporarily
DIt moves behind the rectum during pregnancy
Answer & Solution
Correct answer: B. Its capacity falls as the uterus compresses it
1. The bladder lies anterior to the uterus in females.
2. As the uterus enlarges in late pregnancy it compresses the bladder.
3. Capacity falls, so the bladder fills to its usable limit sooner and urination becomes more frequent.
4. The detrusor is smooth muscle throughout life and does not change into skeletal muscle.
