What is the primary function of the scrotum in the male reproductive system?
Regulating body temperature of the testes
Storing urine
Producing sperm
Carrying sperm to the urethra
The Correct Answer is A
A. Regulating body temperature of the testes: Correct -the scrotum suspends the testes and adjusts their position to keep testicular temperature slightly below core body temperature, which is necessary for optimal sperm production.
B. Storing urine: Incorrect -urine is stored in the urinary bladder, not in the scrotum.
C. Producing sperm: Incorrect -sperm are produced in the seminiferous tubules inside the testes; the scrotum is a protective/powerful thermoregulatory sac, not the sperm-producing tissue.
D. Carrying sperm to the urethra: Incorrect -ducts such as the vas (ductus) deferens carry sperm toward the urethra; the scrotum does not transport sperm.

B. BRCA test: BRCA genetic tests assess hereditary breast/ovarian cancer risk (BRCA1/2), not cervical cancer screening.
C. ELISA test: ELISA is a lab technique for detecting antibodies/antigens (used in many contexts, e.g., HIV testing) but is not a routine screening test for cervical cancer.
D. Mammogram:A mammogram is an imaging test used to screen for breast cancer, not cervical cancer.
Correct Answer is C
Explanation
A. Tubular secretion involves the reabsorption of substances from the renal tubules into the peritubular capillaries.: That describes reabsorption, the opposite of secretion.
B. Tubular secretion is a passive process that occurs in the glomerulus, allowing the filtration of waste products.: Filtration in the glomerulus is a separate, largely passive process; tubular secretion is an active transport process occurring in the renal tubules.
C. Tubular secretion is the movement of substances from the blood in the peritubular capillaries into the renal tubules.: This correctly describes tubular secretion (e.g., H⁺, K⁺, drugs) .
D. Tubular secretion primarily occurs in the Bowman's capsule, facilitating the selective reabsorption of essential nutrients.: Bowman's capsule is the site of filtration, not tubular secretion; selective reabsorption occurs later in the tubules.
