Which of the following processes is required for normal blood clotting?
Activation of plasmin
Activation of heparin
Adequate levels of potassium
Adequate levels of calcium
The Correct Answer is D
a. Activation of plasmin: Plasmin is involved in breaking down blood clots, not in their formation. It is part of the fibrinolytic system.
b. Activation of heparin: Heparin is an anticoagulant that prevents clotting; it is not required for blood clotting.
c. Adequate levels of potassium: Potassium is important for cellular function but does not play a direct role in blood clotting.
d. Adequate levels of calcium: Calcium ions are essential for various steps in the blood clotting cascade, including the activation of certain clotting factors.

Correct Answer is B
Explanation
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.
