Chapter 27, Problem 2
The ovaries are responsible for
(a) The production of female gametes
(b) The secretion of female sex hormones
(c) The secretion of inhibin
(d) All of these
Verified step by step guidance1
Step 1: Understand the role of the ovaries in the female reproductive system. The ovaries are paired organs that have multiple functions related to reproduction.
Step 2: Recognize that the ovaries produce female gametes, which are the eggs or ova. This is a key function necessary for reproduction.
Step 3: Know that the ovaries also secrete female sex hormones, primarily estrogen and progesterone, which regulate the menstrual cycle and secondary sexual characteristics.
Step 4: Be aware that the ovaries secrete inhibin, a hormone that helps regulate the production of follicle-stimulating hormone (FSH) by the pituitary gland.
Step 5: Combine all these functions to conclude that the ovaries are responsible for all the listed activities, making the correct answer the option that includes all of these roles.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Production of Female Gametes
The ovaries produce female gametes called ova or eggs through a process called oogenesis. These gametes are essential for reproduction, as they combine with male sperm during fertilization to form a zygote.

Secretion of Female Sex Hormones
Ovaries secrete key female sex hormones such as estrogen and progesterone. These hormones regulate the menstrual cycle, support pregnancy, and influence secondary sexual characteristics like breast development.

Secretion of Inhibin
Inhibin is a hormone secreted by the ovaries that helps regulate the production of follicle-stimulating hormone (FSH) by the pituitary gland. This feedback mechanism controls the development of ovarian follicles and maintains hormonal balance.
