blood & blood vessels

Part of the circulatory system that

transports blood throughout the body.

Blood Vessels

There are three major types of blood vessels...

Arteries are blood vessels that carry blood away from the heart.

The capillaries are where all of the important exchanges happen in the circulatory system. The capillaries are a single cell in diameter to aid fast and easy diffusion of gases, sugars and other

nutrients to surrounding tissues.

In the circulatory system, veins are blood vessels that carry blood towards the heart.

Veins differ from arteries in structure and function.

Blood is a specialized bodily fluid in animal that delivers necessary substances such as nutrients and oxygen too the cells and transports metabolic waste products away from those same cells.

 Substances that left over which cannot be used by organism.

Blood is circulated around the body through BLOOD VESSELS by the pumping action of the HEART.
