Question
Describe the circulatory system in a fish.
✓
Answer
The fish has a two chambered heart. Oxygenation of the blood takes place in the gills. The oxygenated blood from the gills is supplied to the body parts of the fish where oxygen is utilized and carbon-dioxide enters into it making it deoxygenated. The deoxygenated blood returns to the heart to be pumped into gills again.
