Oviduct of female Frog has a swelling or ovisac for storing

Options

A. Sperms
B. Ova
C. Albumin
D. Urine

Answer

### Step-by-Step Solution:

1. **Understanding the Structure**: The female frog has a pair of oviducts, which are long, coiled, glandular tubes located on either side of the ovaries.

2. **Identifying the Oviduct's Function**: The oviducts serve a crucial role in the reproductive system of the female frog. They are responsible for transporting the ova (eggs) from the ovaries to the outside of the body.

3. **Recognizing the Ovisac**: At the posterior end of each oviduct, there is a dilation known as the ovisac. This structure is thin-walled and ciliated, which aids in the movement of the ova.

4. **Storage Function**: The primary function of the ovisac is to store the ova. The ovisac allows for the storage and agglutination (clumping together) of the ova, which are the female gametes.

5. **Eliminating Incorrect Options**:
- **Sperms**: These are the male gametes and are not stored in the female frog's oviduct.
- **Albumin**: This is a protein that covers the ova but is not stored in the oviduct.
- **Urine**: This is stored in the ureters and not in the oviduct.

6. **Final Answer**: Therefore, the correct answer to the question is that the oviduct of the female frog has a swelling or ovisac for storing **ova**.
