What role does it play?
 The circulatory system moves
nutrients and gas waste to and
from cells. Also it fights diseases
and stabilizes body temperature. It
delivers oxygen to the body
through the blood stream.
What are the main organs?
 The main organs are the heart, blood and the blood
vessels and the
 The heart pumps blood through the body. The blood
travels through the blood vessels and delivers oxygen
to the body. The blood vessels help the blood travel
to the organ systems.
What are the main organs?
 Before each heart beat the heart fills up with
blood and when it contracts it pushes the
blood out and into the arteries.
 The blood vessels carry the blood through out
the body, giving oxygen to the body and then
returns to the heart.
 The Blood travels through the body and gives
oxygen to the body.
How do these organs work together?
The circulatory system allows oxygen from breathing in
to the bloodstream as well release gas waste such as
carbon dioxide. This oxygen is carried by the blood in
your blood vessels (specifically your arteries) to all the
cells, tissues, and organs in the body. In return, the
blood that is carried by the veins and pumped by the
heart go back , and the process repeats and bringing
oxygen to the body.
What systems are the circulatory
system connected to?
 The circulatory system and the respatory system are
closer together in the body. Oxygen, is an essential
part of the metabolic proses of nearly all cells is
gathered through the respitory system and
transported through the body's of complexed
organisms. These 2 systems also eliminated carbon
dioxide, which is a metabolic waste product. The
respatory system and the circulatory system are
connected through the lungs where the exchange of
oxygen and carbon dioxide occur.
What systems are the circulatory
system connected to?
 Another system that is connected to the circulatory
system is the digestive system. The digestive system
absorbs nutrients and then give it to the blood
stream. Then the blood stream gives nutrients to
other organs
What are the levels of human
organization?
 The levels of organization we start with Organs then the tissues ,
the cells that make the tissues. For this slide we chose the heart
as demonstration for organs.
 One of the types of tissues that makes the heart is the
cardiovascular(cardiac) muscle tissue. The cardiac muscle tissue
is only found in the heart.
 Then there are cardiac muscle cells . They make up the tissue
that makes up part of the heart.
This is a picture of
cardiac muscle tissue .
2 common diseases
 Arteriosclerosis is one of the most common diseases
for the circulatory system. This is when there is too
much fat in the arteries and it causes the walls to
thicken and stiffen. It is caused by too much fat,
cholesterol and calcium. Lifestyle changes can be the
only treatment needed to cure arteriosclerosis.
2 common diseases
 Another common disease is hypertension but
commonly called high blood pressure. This disease
causes the heart to work harder. Some complications
are heart attack, stroke or kidney failure. The causes
are high amounts of sodium, obesity, lack of exercise,
drugs, alcohol, poor diet and smoking. Some ways
you can prevent is with a healthy diet and medication
prescribed by your doctor.
How you can maintain a healthy
circulatory system!
 Some ways you can maintain a healthy
circulatory system is to exercise your
heart. You can do this by being active
like playing basketball or jump rope.
Also you can eat healthy food like an
apple or broccoli. Try to not have pop a
lot. Also don’t smoke!
Professions that involve the
circulatory system
 The first profession is heart surgeon – when someone has
a heart attack they might need surgery! So a heart
surgeon is called in and might have to operate. This person
would work at a hospital.
 The second profession is cardiac and vascular surgeonsometimes medication can slow the progress of heart
disease, some patients require surgery to fix damage to
the heart and the blood vessels. This is the work of cardiac
and vascular surgeons. They perform bypasses and openheart surgery, as well as valve repairs and they also work in
a hospital
Did you know?
 The circulatory system is extremely long.
 Physicians followed an incorrect model of the
circulatory system for 1500 years.

It takes about 20 seconds for one blood cell to
circle the entire body.

Red blood cells must squeeze through blood
vessels.

The heart beats about 3 billion times in a person’s
life.
