Humans have a closed circulatory system with a heart that pumps blood through a network of vessels, while worms have an open circulatory system where blood is pumped through a simple system of vessels and sinuses by the contraction of the body wall.

Humans have specialized blood cells like red blood cells, white blood cells, and platelets, while worms may have fewer types of blood cells.
