b. transports urine
c. stores and matures sperm
d. creates seminal fluid

1. which of the following shows the correct path sperm travel?

a. epididymis → vas deferens → ejaculatory duct → urethra
b. vas deferens → epididymis → urethra → ejaculatory duct
c. epididymis → ejaculatory duct → vas deferens → urethra
d. urethra → ejaculatory duct → vas deferens → epididymis

Explanation:

Question 1

Sperm development requires a temperature slightly cooler than the body's core temperature. The scrotum's temperature regulation supports this, so option C is correct. Options A (testosterone production isn't driven by scrotal temperature), B (blood flow reduction isn't the reason), and D (hormone release prevention is incorrect) are eliminated.

Question 2

Seminiferous tubules, where sperm are produced, are located within the testes. The scrotum holds the testes (not the site of production), vas deferens transports sperm, and epididymis matures sperm. So option B is correct.

Question 3

Testicular torsion twists the spermatic cord, cutting off blood supply to the testicle. This is a medical emergency. Option A (hormone imbalance isn't the main emergency reason), B (testosterone release stopping isn't the key), and D (increased sperm production is false) are incorrect.

Question 4

Answer:

C. To ensure proper sperm development
