The circulatory system
is the body system that
transports Nutrients,
OXYGEN & CELLULAR
WASTE throughout
the body.
Circulatory System
consists of:
Blood
Blood Vessels
Heart
Blood is comprised of
•Plasma
•Blood cells
•Platelets
Plasma
is the liquid part of
blood.
The 2 types of blood
cells are:
1 –Red Blood Cells
2 – White Blood Cells
Platelets
help your blood clot
The function of White Blood Cells:
 To attack, surround and destroy
pathogens that enter the body and
prevent them from causing
infection.
 When you have an infection, the
number of white blood cells
increases.
The function of Red blood
cells:
To carry oxygen
They are the most numerous
type of blood cells.
They live about 100 days
3 Major types of
Blood Vessels
are:
1.Arteries
2.Veins
3.Capillaries
Arteries
 These are the blood
vessels that carry blood
AWAY
from your heart.
Veins
Are blood vessels
that carry blood
TO
the heart
Cappillaries
Are tiny blood
vessels that connect
arteries and veins.
The Heart
is a
Muscle with
4 Chambers that
pump blood
throughout the body.
Atrium
Is the
Upper Chamber
of the Heart
Ventricle
Is the
lower chamber
of the heart
Aorta
Is the main artery in the
body.
The aorta branches into
smaller arteries and
blood flows through to
all parts of the body.
Blood Pressure
Is the force of blood
against the artery
wall.
Systolic Blood Pressure
Is the force of blood
against the artery walls
when the heart is
beating.
Diastolic Blood Pressure
Is the force of blood
against the artery
walls
BETWEEN
Heart beats.
Transfusion
Is the transfer of blood
between people.
Blood Type
Is the type of red
blood cells a
person has.
Blood types:
A , B , AB ,or O
6 Ways to care for your
Circulatory System:
1. Reduce the amount of fat in your
diet.
2. Exercise Regularly
3. Avoid Tobacco Products
4. Maintain a Healthful Weight
5. Practice Stress Management Skills
6. Spend time with loving Friends &
Family Members
1 - Oxygen-poor blood (shown in blue) flows
from the body into the right atrium.
2 - Blood flows through the right atrium into the
right ventricle.
3 - The right ventricle pumps the blood to the
lungs, where the blood releases waste
gases and picks up oxygen.
4 - The newly oxygen-rich blood (shown in red)
returns to the heart and enters the left
atrium.
5 - Blood flows through the left atrium into the
left ventricle.
6 - The left ventricle pumps the oxygen-rich
blood to all parts of the body.
