In which animal is circulatory system absent?

Animals without circulatory systems: Simple animals consisting of a single cell layer, such as the (a) sponge, or only a few cell layers, such as the (b) jellyfish, do not have a circulatory system. Instead, gases, nutrients, and wastes are exchanged by diffusion.

Why do fish only need a single circulatory system?

All animals need blood to be transported to the lungs (or gills in fish) in order to be oxygenated. In fish, once the blood leaves the gill capillaries it travels directly to the rest of the body before travelling back to the heart. This is called single circulation.

What’s the circulatory system do?

The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides.
