Question

In tracing the path of sperm, you would mention the vasa deferentia before the a. testes. b. epididymides. c. urethra. d. uterus.

Short answer

The correct order in tracing the path of sperm is Testes -> Epididymides -> Vasa Deferentia -> Urethra. Therefore, before the vasa deferentia, you would mention the epididymides. The correct answer is b. epididymides.

Step-by-step solution

Understand the Male Reproductive System

Familiarize yourself with the various parts of the male reproductive system, including the testes, epididymides, vasa deferentia, urethra, and other structures.

Determine the Role of Testes

The testes are the primary male reproductive organs, responsible for the production of sperm and hormones, such as testosterone. They are the starting point for the sperm's journey.

Determine the Role of Epididymides

The epididymides are long, coiled tubes that connect the testes to the vasa deferentia. Their primary function is to store and transport sperm and provide a favorable environment for sperm maturation.

Determine the Role of Vasa Deferentia

The vasa deferentia (singular: vas deferens) are long, muscular tubes that transport sperm from the epididymides to the urethra. They are responsible for the next step in the sperm's journey.

Determine the Role of Urethra

The urethra is a tube that runs through the penis, allowing urine and semen to exit the body. It is the final conduit for the expulsion of sperm.

Determine the Role of Uterus

The uterus is a part of the female reproductive system and has no direct role in the path of sperm within the male reproductive system.

Determine the Correct Order of Sperm Path

Considering the roles of the various structures, the correct path of sperm is as follows: Testes -> Epididymides -> Vasa Deferentia -> Urethra. Since we are asked to mention what comes before the vasa deferentia, the correct answer is: b. epididymides
