The fertilization in human occurs at the junction of

Options

A. Infundibulum and ampulla
B. isthmus and fundus
C. Ampulla and isthmus
D. cervix and fundus

Answer

**Step-by-Step Solution:**

1. **Understanding Gametes**: In humans, fertilization involves the fusion of male and female gametes. The male gamete is called sperm, and the female gamete is called the ovum (or egg).

2. **Location of Fertilization**: Fertilization occurs within the female reproductive system. Specifically, it takes place in the fallopian tubes, which are part of the female reproductive tract.

3. **Anatomy of the Fallopian Tube**: The fallopian tube has several parts:
- **Infundibulum**: The funnel-shaped opening that captures the ovum.
- **Ampulla**: The swollen region of the fallopian tube where fertilization primarily occurs.
- **Isthmus**: The narrow section of the fallopian tube that connects to the uterus.

4. **Main Site of Fertilization**: The ampulla is recognized as the main site of fertilization due to its structure and location. The sperm travels through the female reproductive tract to meet the ovum here.

5. **Conclusion**: Therefore, the fertilization in humans occurs at the junction of the ampulla and isthmus of the fallopian tube.

**Final Answer**: The fertilization in humans occurs at the junction of the ampulla and isthmus of the fallopian tube.
