Question

The given diagrams represent the reproductive systems in the human male and female. The blockages shown at A and B would most likely interfere with the ability to:

• A. Transport gametes
• B. Produce mature gametes
• C. Eliminate waste products through the urethra
• D. Express secondary sex characteristics

Answer 1

Answer: (A)

Transport gametes

• A - represents vasa deferentia that transports sperm from the testes to the urethra.
• B - represents fallopian tubes or oviducts that play an important role in the transport and fertilization of the egg.
• So, blockage at the site (A) and (B) interferes with the transport of gametes and will prevent pregnancy.
• The surgical blocking of the vas deferens to prevent the passage of sperms is known as vasectomy.
• The surgical blocking of the oviduct is known as tubectomy.

So, the correct answer is option A.
