The nature of the blood that flows through the heart in fish is deoxygenated. Here's a step-by-step explanation:

1. Fish, like all vertebrates, have a closed circulatory system, meaning the blood is always contained within vessels (arteries, veins, capillaries) or the heart.

2. The heart pumps the blood, which is deoxygenated, to the gills.

3. At the gills, the blood gets oxygenated. This is where the gas exchange happens - oxygen from the water enters the blood, and carbon dioxide (a waste product) is expelled from the blood into the water.

4. The oxygenated blood then travels from the gills to the rest of the body, delivering oxygen to the cells.

5. The now deoxygenated blood returns to the heart, and the process starts again.

So, the blood that flows through the heart in fish is deoxygenated.
