The Circulatory
System
what does it mean
&
how it applies to you
FUNCTIONS
 1.
To pump/send/deliver blood carrying
oxygen and nutrients to the body
 2.
To take away wastes (CO2 and other by
products)
Components

Heart

Muscle that pumps blood
throughout the body.
• Blood Vessels



Arteries - carries
oxygenated blood (red)
Veins - carry oxygen
depleted blood
Capillaries-small vessles
that allow the exchange
of oxygen and wastes to
cells
BLOOD
 Red
Blood Cells
 White Blood Cells-fight infection and
disease
 Platelets-help blood clot
 Plasma-liquid part of blood
 Hemoglobin-iron in red blood cells that
binds and carries oxygen
Process
 The
blood vessels are a closed system,
arteries… capillaries… veins; the heart
pumps with every beat it pushs blood
through this system, sending blood to ever
cell in the body.
Problems
 Cardiovascular
disease-plaque or fatty
deposits build up inside ateries or veins,
closing down those vessels and blocking
blood from the heart
 Anemia-not enough iron in the blood,
therefore blood does not carry enough
oxygen-easily tired and winded
