arteries, capillaries and veins
Yes I think so
A fish heart typically connects to two main arteries: the ventral aorta, which carries blood to the gills for oxygenation, and the dorsal aorta, which distributes oxygenated blood to the rest of the body. Additionally, fish have numerous veins that return deoxygenated blood back to the heart, primarily through the sinus venosus, which collects blood from the body. Overall, while the exact number of veins can vary, the heart is primarily connected to these two main arteries and a network of veins.
