Animal circulatory systems differ in the number of heart chambers and the number of circles through which blood flows. Fish have the simplest circulatory systems of vertebrates and unidirectional blood flows from the chambered heart through the gills and then to the rest of the body. The function of the circulatory system is to distribute nutrients, oxygen and hormones to all parts of the body and remove metabolic waste that is transported to the excretory organs. The circulatory system consists of two anatomically connected circles, which are blood, venous arteries, or primary blood vessels. Through it blood flows and the secondary lymphatic system or lymphatic system, through which the lymph flows.
