The butterfly's circulatory system consists of a long tubular heart and hemocoel (spaces between organsfor blood to move). The blood is pumped out to tissues through the hemocoel, but it simply seeps back through the tissue, and it doesn't carry oxygen, just nourishment. Air enters through pores called spiracles and moves through tubes through the body, with gas exchange occurring at the ends of those tubes (tracheae).

Some dont have any at all but most have closed cirrculatory systems.
open circulatory systems
yes
Fish have closed-loop circulatory systems.
Birds have closed circulatory systems, where blood flows within vessels and does not come in direct contact with the surrounding tissues. This system allows for efficient circulation and delivery of oxygen and nutrients throughout the bird's body.
They have closed circulatory systems.
Rabbits have a closed circulatory system, meaning that their blood flows through a series of vessels and the heart pumps it continuously around the body. This system allows for efficient transport of oxygen, nutrients, and waste products throughout the rabbit's body.
open circulatory systems have sinuses and only have blood vessels
There are two main types of circulatory systems:1. Open2. ClosedIn an open circulatory system, blood mixes with internal organs directly. Organisms with this type of system do not have a true heart or capillaries. Instead of a true heart, there are blood vessels that act as pumps to force the blood along. Instead of capillaries, blood vessels join directly with open sinuses.In a closed circulatory system, blood is pumped through a closed system of arteries, veins, and capillaries.(:
Amphibians have closed circulatory system Closed
A humans circulatory system is closed. Large creatures tend to have a closed system, while smaller creatures like insects and crustaceans have open circulatory systems. Closed is when there are vessels and the blood stays there. Open is when blood floats around the body. Hope it helps:)
not all open circulatory systems transport oxygen. Insects have no oxygen in their blood
