Hormones involved in birth and a variety of bodily functions are classified under which two body systems?

• A. Circulatory and Nervous
• B. Reproductive and Endocrine
• C. Skeletal and Immune
• D. Integumentary and Digestive

Answer: (B)

Hormones play a crucial role in regulating various bodily functions, and they are primarily associated with the endocrine system, which is responsible for hormone production and secretion. The reproductive system is also intricately linked to hormonal regulation, as it involves processes such as ovulation, menstruation, and pregnancy that are governed by specific hormones like estrogen, progesterone, and testosterone.

The partnership between the reproductive and endocrine systems is essential in maintaining reproductive health and facilitating processes related to reproduction, including ovulation and the menstrual cycle in females and sperm production in males. In contrast, the other body systems listed do not primarily regulate hormonal functions: the circulatory system is involved in transporting blood and nutrients, the skeletal system supports and protects the body, the immune system defends against pathogens, the integumentary system covers and protects the body, and the digestive system processes food. Therefore, the identification of the reproductive and endocrine systems as key players highlights their significant roles in hormone-related functions and reproductive health.
