Why do we need the Circulatory System?
Parts
Functions
Circulation Video
*Moves blood through body to transport oxygen and nutrients to cells
*Removes cell waste & carbon dioxide
*Helps to regulate body temperature
*Fights infections
* Heart (muscle)
* Arteries, Veins, Capillaries (blood
vessels)
*Blood Cells

*Heart-
Pumps blood throughout the body
*Arteries-
Carry blood AWAY from heart
* Veins-
Carry blood TO heart
* Capillaries-
Bring nutrients and oxygen to tissues, carry out carbon dioxide and waste
*Red Blood Cells-
Carry oxygen
*All of this regulates the body temperature and oxygen is moved through the body
Heart
*The heart is a muscle in the human body that pumps blood to all of the human bodies cells
*It's made up of 2 upper chambers (the left & right atria) and 2 lower chambers (left & right vetricles) four chambers all together
*The heart controls the flow of blood throughout the whole body
Blood Cells
Blood Vessels
Red Blood Cells:
~The most common type of blood cell
~They deliver oxygen to the body tissues through blood streams
White Blood Cells:
~They defend the body against infectious disease & foreign material
*Arteries:
Carry Oxygenated Blood away from the Heart
*Veins:
They carry Deoxygenated Blood from body back to the Heart
*Capillaries:
The smallest blood vessels in the body, they allow exchange of water, oxygen, carbon dioxide & nutrients between blood
and body tissue
