Tracing the flow of blood through the body
When a heart contracts and forces blood into the blood vessels, there is a certain path that the blood follows through the body.The blood moves through pulmonary circulation and then continues on through systemic circulation.
Identification of types of blood vessels
Any of the fine branching blood vessels that form a network between the arterioles and venules
Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart.
