The main structures of the cirulatory system are: the heart, the arteries, veins and capillaries.
circulatory system does.
the heart is part of the circulatory system in the body.
Single cell organisms do not have a circulatory system like humans because they are single-celled and do not have complex internal structures. Instead, they rely on simple diffusion for the exchange of gases and nutrients.
The circulatory system works with digestive system to circulate the nutrients to all the body parts. The nutrients are digested and absorbed by the digestive system. The circulatory system circulates the nutrients throughout the body.
In an open circulatory system, the blood does not flow in closed vessels and surrounds the organs directly within the body cavity. This type of circulatory system is found in invertebrates like insects and mollusks.

The circulatory system includes three major vessels. These are capillaries, arteries and veins. Arterioles and venules are part of the vessels as well.
Bacteria do not have a circulatory system like humans. Instead, they rely on diffusion to transport nutrients and waste products across their cell membranes. This process is efficient for small, single-celled organisms without complex body structures.
