Options

B. uterus
C. scrotal sacs
D. oviducts

Answer

To solve the question "One of the following is not a part of the human female reproductive system," we will analyze each of the options provided:

1. **Ovary**: The ovary is a crucial part of the female reproductive system. It is responsible for producing female gametes (eggs) and hormones such as estrogen and progesterone. Therefore, the ovary is a part of the human female reproductive system.

2. **Uterus**: The uterus, also known as the womb, is where the fertilized egg implants and develops into a fetus during pregnancy. It is an essential component of the female reproductive system. Thus, the uterus is also a part of the human female reproductive system.

3. **Scrotal sac**: The scrotal sac is a part of the male reproductive system. It contains the testicles (testes), which produce male gametes (sperm). Since the scrotal sac is associated with male reproduction, it does not belong to the human female reproductive system.

4. **Oviducts**: Oviducts, also known as fallopian tubes, are part of the female reproductive system. They transport the eggs from the ovaries to the uterus and are involved in fertilization. Therefore, oviducts are also part of the human female reproductive system.

Based on this analysis, the option that is not a part of the human female reproductive system is the **scrotal sac**.

**Final Answer**: Scrotal sac
