The circulatory system
The circulatory system
is an organ system that
passes nutrients (such as
amino acids, electrolytes
and lymph), gases,
hormones, blood cells,
etc. to and from cells in
the body to help fight
diseases and help
stabilize body
temperature and pH to
maintain homeostasis.
The main components of the
human cardiovascular system

The main components of the
human cardiovascular system
are the heart, the veins, and
the blood vessels. It includes:
the pulmonary circulation, a
"loop" through the lungs where
blood is oxygenated; and the
systemic circulation, a "loop"
through the rest of the body to
provide oxygenated blood. An
average adult contains five to
six quarts (roughly 4.7 to 5.7
liters) of blood, which consists
of plasma, red blood cells,
white blood cells, and
platelets.
Pulmonary circulation

Pulmonary circulation
is the portion of the
cardiovascular system
which carries oxygendepleted blood away
from the heart, to the
lungs, and returns
oxygenated blood back
to the heart.
Systemic circulation

Systemic circulation is
the part of the
cardiovascular system
which carries oxygenated
blood away from the
heart to the body, and
returns deoxygenated
blood back to the heart.
This physiologic theory of
circulation was first
described by William
Harvey.
Coronary circulation

Coronary circulation is
the circulation of blood in
the blood vessels of the
heart muscle (the
myocardium). The vessels
that deliver oxygen-rich
blood to the myocardium
are known as coronary
arteries. The vessels that
remove the deoxygenated
blood from the heart
muscle are known as
cardiac veins.
Heart

The heart pumps
oxygenated blood to the
body and deoxygenated
blood to the lungs. In the
human heart there is one
atrium and one ventricle
for each circulation, and
with both a systemic and
a pulmonary circulation
there are four chambers
in total: left atrium, left
ventricle, right atrium and
right ventricle.
Cardiovascular diseases

Heart diseases or cardiovascular diseases
are the class of diseases that involve the heart
or blood vessels (arteries and veins).
 Most countries face high and increasing rates of
cardiovascular disease. Each year, heart
disease kills more Americans than cancer.
 There is therefore increased emphasis on
preventing atherosclerosis by modifying risk
factors, such as healthy eating, exercise and
avoidance of smoking.
Smoking is bad for your health.
Smoking harms nearly
every organ of the body.
Cigarette smoking causes
87 percent of lung cancer
deaths. It is also
responsible for many
other cancers and health
problems. These include
lung disease, heart and
blood vessel disease,
stroke and cataracts.
Your smoke is also bad for other
people

Your smoke is also
bad for other people they breathe in your
smoke secondhand
and can get many of
the same problems as
smokers do.
Quit Smoking

Quitting smoking can reduce your risk of these
problems. The earlier you quit, the greater the
health benefit.
Healthy eating
Obesity occurs over time when you eat more calories
than you use. The balance between calories-in and
calories-out differs for each person. Factors that might
tip the balance include your genetic makeup, overeating,
eating high-fat foods and not being physically active.
The Medical Hazards of Obesity
Regular exercise is a
critical part of staying
healthy. People who
are active live longer
and feel better.
Exercise can help you
maintain a healthy
weight. It can delay or
prevent diabetes, some
cancers and heart
problems.
10 Tips to healthy eating and
physical activity for you.
Start your day with breakfast
Get Moving!
Snack smart.
Get fit with friends or family.
Work up a sweat.
Balance your food choices - don't eat
too much of any one thing
Eat more grains, fruits and vegetables.
Join in physical activities at school.
Foods aren't good or bad.
A healthy eating style is like a puzzle with many
parts. Each part -- or food -- is different
Make healthy eating and physical activities fun!
BE HEALTHY!
