Introduction and Overview of the

Cardiovascular System​

The cardiovascular (CV) system is the body’s transport system. It

provides
​

• Nourishment.
  ​

• Cleanup services.
  ​

• Communication.​

Two parts:
​
Heart = cardi/o or coron/o
​

Blood vessels (vascular) = angi/o, vas/o, vascul/o ​

​9.1 Word Parts of the Cardiovascular System 1​

The heart functions to move blood throughout the body’s blood vessels.​

Four chambers
​

• 2 atriums = atri/o (2 upper chambers)

  ​

• 2 ventricles = ventriculo/o (2 lower chambers)​

Separated into the left and right sides by the septum = sept/o (partition, dividing wall of muscle)​

• The left side receives blood from the lungs and delivers oxygen-rich blood to the body.

• The right side receives blood from the body and delivers oxygen-poor blood to the lungs.​

​9.1 Word Parts of the Cardiovascular System 2​

A valve = valvul/o is placed between each atrium and ventricle.
​

• Right atrioventricular valve (tricuspid valve).

• ​

Left atrioventricular valve (mitral or bicuspid valve).

​

A valve is placed between each ventricle and large artery
.​

• Pulmonary valve. = pulmon/o (lung)​

• Aortic valve. = aort/o (aorta)​

3 types of vessels

• artery= (arteri/o) takes blood away from the heart

• vein= (phleb/o, ven/o takes blood to the heart

• Capillaries - connect arteries & veins
