Ventricle of frog contains:

Options

A. oxygenated blood
B. deoxygenated blood
C. no blood
D. mixed blood

Answer

### Step-by-Step Solution:

1. **Understanding the Heart Structure of a Frog**:
- The heart of a frog is a 3-chambered organ consisting of two auricles (atria) and one ventricle.

2. **Identifying the Function of Each Chamber**:
- The two auricles receive blood: one auricle receives oxygenated blood from the lungs (right auricle), while the other receives deoxygenated blood from the body (left auricle).

3. **Examining the Ventricle**:
- The ventricle is responsible for pumping blood out of the heart. In frogs, this ventricle does not have a complete septum (partition) that separates the oxygenated and deoxygenated blood.

4. **Understanding Blood Flow in the Ventricle**:
- Due to the absence of a complete septum, the ventricle contains a mixture of oxygenated and deoxygenated blood. This is referred to as mixed blood.

5. **Conclusion**:
- Therefore, the ventricle of a frog contains mixed blood, which is a combination of both oxygenated and deoxygenated blood.

### Final Answer:
The ventricle of a frog contains mixed blood.
