Components of Blood
 Blood is actually made up of several things.
 Red Blood Cells
 White Blood Cells
 Plasma
 Platelets

Your Blood is made of
Red Blood Cells


Plasma
 Liquid part of blood
 Pale yellow mixture of water, proteins and salts
Red Blood Cell
 They carry oxygen to all parts of the body.
 Remove Carbon
Dioxide.
 Remove other wastes.

White Blood Cells
 White Blood Cells
 Fight and kill germs that may enter your bloodstream
White Blood Cells act as cops patrolling the bloodstream
White blood cell attacking an infection

Platelets
A large scab Platelets surrounding a Red Blood Cell.
 Platelets
 Form “scabs” when you cut yourself
 Helps stop the bleeding

Blood Types
Percentage of blood types worldwide
 Not all blood is the same.
 Structures on the surface of blood can differ because of your genetic makeup.
 Currently Scientists have grouped these structures into 8 different blood types.

Blood Transfusions
Blood Transfusion
Recent research suggests that this blood compatibility chart may change in the future as our understanding of blood improves.

Blood Incompatibility
When incompatibility blood mixes it clumps together, this can be fatal!

3 Major Parts of the Circulatory system
 Blood Vessels – routes for blood to travel
 Heart – pumps or pushes blood through body
 Blood – carries oxygen and nutrients through the body

Blood Vessels - Overview


Your body resembles a large roadmap, There are “routes” or Blood vessels that take you blood to the heart and the rest of your body.
There are 3 types of blood vessels:



Arteries
Capillaries
Veins

Blood Vessels - Detail
 Arteries: The largest and thickest of the blood vessels.
 Carry blood away from the heart to all the cells in the body.
 Capillaries: the smallest blood vessels.
 The exchange of oxygen and carbon dioxide take place in capillaries.
 Bring blood to all tissue in the body.
 Veins: Carry blood back to the heart.

Clogged Blood Vessels
If you eat too much fatty foods this is what happens to your blood vessels!
Fat deposits in a blood vessel.
A clogged blood vessel

Heart Attack
When the blood vessels of the heart are blocked it can cause a heart attack!

Causes of blocked blood vessels
Obesity
 High blood cholesterol
(too much fat)
 Smoking
 Physical activity
 Obesity
 Diabetes
 Stress and anger

The Heart




The heart is a vital organ that basically serves as a pump.
The heart pumps blood around the body.
To do this the heart is made up of a special kind of muscle tissue.
This muscle tissue allows the heart to beat constantly.
