3. The Heart and Blood
Vessels
The circulatory system consists of the heart
and the blood vessels. These structures
supply the body with a constant flow of
blood, which brings oxygen and nutrients to
the tissues and carries waste products
away.
Blood is pumped around the body by
rhythmic contractions (beats) of the heart
muscle. The blood runs through a network
of vessels divided unto three types: arteries,
veins and capillaries. The forces that is
exerted by the blood flow through the main
arteries is called blood pressure. It caries
with the strength and phase of the heart
beat, the elasticity of the arterial walls and
the volume and thickness of the blood.
