Which two body systems are responsible for the production of estrogen and the thickening of the lining of the uterus?

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

Answer: (B)

The correct answer is the reproductive and endocrine systems. The reproductive system is directly involved in the production of estrogen, which is primarily produced by the ovaries. Estrogen plays a crucial role in regulating the menstrual cycle and is vital for the thickening of the uterine lining in preparation for potential pregnancy. The endocrine system regulates hormone levels, including estrogen, and ensures that the appropriate hormonal signals are distributed throughout the body. This system’s role is essential for coordinating complex functions such as growth, metabolism, and reproductive processes, which includes the menstrual cycle regulated by estrogen. In contrast, the other body systems listed do not have direct roles in the production of estrogen or in the thickening of the uterine lining. The nervous system, while it interacts with endocrine functions, does not produce hormones like estrogen. The muscular and circulatory systems are involved in movement and the transport of blood, respectively, but do not play roles in hormone production. The skeletal and immune systems have their specific functions, unrelated to hormone synthesis or uterine lining preparation.
