**Questions and Answers:**

6. **Describe the pathway (ducts) that a sperm cell would travel from its production to ejaculation. What are the three accessory glands of the male reproductive system?**

**Answer**: Sperm is produced in the testes, matures in the epididymis, travels through the vas deferens, mixes with fluids from the seminal vesicles, prostate gland, and Cowper’s gland, and is ejaculated through the urethra. The three accessory glands are the seminal vesicles, prostate gland, and Cowper’s gland.

7. **What is the difference between Leydig cells and Sertoli cells in the testes?**

**Answer**: Leydig cells produce testosterone and are located in the interstitial spaces of the testes. Sertoli cells nourish sperm cells and are found within the seminiferous tubules.

Expert Solution

Step 1: Introduction

According to Bartleby policy we have to solve only first question please post rest of the questions separately.

The male reproductive system performs several roles, including the generation of gametes, the production of hormones such as testosterone, and the transfer of gametes into the ejaculate and the female reproductive system. The male reproductive organ system is made up of outward features that aid in sexual function and protection, as well as interior structures that operate to produce gametes and other chemicals that aid in sexual activities.
