Answer 2

Answer:

Fishes have single circulation.

Explanation:

Single circulation:

When referring to a circulatory system in fish,

The term "single circulation" describes one in which blood only passes through the heart once throughout each full circuit of the body. Take the instance of twofold circulation.

In a closed circulatory system, a single or double circulation pattern can be discovered. Blood only passes through the heart once throughout each complete cycle in fish, which have a single pattern of circulation. The heart draws blood with low oxygen content from the body's tissues, which is subsequently pushed to the gills.

All fish have the same type of circulatory system. A fish's body's circulatory system only passes through the heart once as blood, completing a full circuit.

The gills, where the gas exchange takes place, get blood from the heart (carbon dioxide is released and oxygen is absorbed). Before returning to the heart, the oxygenated blood that has just left the gills goes to other parts of the body.
