Systemic circulation
A goldfish's body is made of scales, fins, organs, and bones covered by a layer of skin.
Female goldfish have ovaries to produce eggs, and reproduce externally. Male goldfish have internal testes, and they also reproduce externally.

Systemic circulation
heart -Heart -Lungs -Muscles -valves
In this, blood completes its circulation from left ventricle to right auricle through body organs. Another type of circulation in our body is Pulmonary circulation.
The four routes of circulation in the body are pulmonary circulation (heart to lungs and back), systemic circulation (heart to body and back), coronary circulation (heart's blood supply), and portal circulation (digestive organs to liver and back).
