Which of the following structures is located at the neck of the bladder and surrounds the urethra in a male client?
Testes
Prostate
Rugae
Bulbourethral
The Correct Answer is B
a: Testes - The testes are located outside the body cavity within the scrotum and are responsible for producing sperm and testosterone.
b. Prostate: The prostate gland is a male reproductive organ located at the neck of the bladder and surrounds the urethra. It plays a role in the production of seminal fluid, which nourishes and transports sperm.
c: Rugae - Rugae are folds in the mucous membrane lining the urinary bladder that allow it to stretch as it fills with urine; they do not surround the urethra.
d: Bulbourethral - The bulbourethral glands (Cowper's glands) are pea-sized glands located below the prostate gland that secrete a clear fluid into the urethra during sexual arousal, but they do not surround the urethra at the neck of the bladder.

Correct Answer is B
Explanation
a. Pulmonary: The pulmonary valve separates the right ventricle from the pulmonary artery, which carries blood to the lungs.
b. Atrioventricular: The heart has four chambers: two upper atria and two lower ventricles. The atrioventricular valves (AV valves), also known as tricuspid and mitral valves, separate the atria from the ventricles and prevent blood from flowing backward from the ventricles to the atria.
c. Semilunar: Semilunar valves (aortic and pulmonary) are located at the base of the aorta and pulmonary artery, preventing blood from flowing back into the ventricles.
d. Aortic: The aortic valve separates the left ventricle from the aorta, the main artery carrying blood away from the heart to the body.
Correct Answer is C
Explanation
a. The right ventricle chamber has a smaller overall capacity than the left ventricle: While true, this doesn't directly explain the difference in muscle thickness.
b. The right ventricle receives blood from right atrium, which has lower pressure than left atrium: Both ventricles receive blood from low-pressure atria. The pressure difference is between the circulation systems they pump blood into.
c. The right ventricle pumps a smaller blood volume than the left ventricle. The right ventricle pumps blood to the lungs, a low-pressure system. Therefore, the right ventricle wall (myocardium) is thinner than the left ventricle wall. The left ventricle pumps blood against the higher resistance of the systemic circulation, so its wall is much thicker and stronger.
d. The right ventricle pumps blood into pulmonary circulation, which has lower resistance than systemic circulation: This is the core reason for the difference in muscle thickness.
