FUNCTIONS OF CARDIOVASCULAR
SYSTEM
The four major functions of the cardiovascular system
are:
1. ToTransport of nutrients, oxygen, and hormones
to cells throughout the body and removal of metabolic
wastes
2. Protection of the body by white blood cells,
antibodies, and complement proteins that circulate in
the blood and defend the body against foreign
microbes and toxins.
3. Toprotect the body from blood loss after injuries.
4. To help maintain temperature, fluid balance and
water content within the body.5

CARDIOVASCULAR SYSTEM
ANATOMY
The cardiovascular system consists of the heart,
blood vessels, and the approximately 5 liters of
blood that the blood vessels transport.
Heart :
Theheart is a muscular pumping organ located
medial to the lungs along the body’s midline in
the thoracic region. About about 2/3 of the heart is located on the
body’s left side with the other 1/3 on right.
Your heart is about the size of your clenched fist 6
