The correct Answer is:
To answer the question regarding the triangular structure associated with the heart of a frog, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Structure**: The question asks for a specific structure associated with the heart of a frog that is triangular in shape and located on the dorsal side. 2. **Understand the Function of Vena Cava**: The vena cava are major veins that carry deoxygenated blood back to the heart. In frogs, this blood is received by a specific chamber before it enters the right side of the heart. 3. **Locate the Chamber**: The chamber that receives blood from the vena cava is not the right atrium but another structure that is located at the dorsal side of the heart. 4. **Identify the Correct Structure**: The triangular structure that receives blood from the vena cava is known as the **sinus venosus**. This structure is crucial as it collects deoxygenated blood before it moves into the right atrium. 5. **Conclusion**: Therefore, the correct answer to the question is that the triangular structure associated with the heart of the frog, present on the dorsal side and receiving blood through the vena cava, is the **sinus venosus**. ### Final Answer: The triangular structure associated with the heart of the frog that is present on the dorsal side and receives blood through major veins called vena cava is the **sinus venosus**. ---
