Key Question: What is the
system and what are its
functions? (jobs) Kiana H.
The circulatory system is the
body’s transport system. It’s mad
up of a lot of organs. The Heart
pumps the blood and the arties
and veins transport it. Oxygen
rich blood leaves the left side of
the heart and enters the biggest
artery called the aorta. The
aorta branches into smaller
arteries which then branch into
smaller vessels that transport
all over the body.
More information
When blood enters the smallest
blood vessels named capillaries
and are found in body tissue it
gives nutrients and oxygen to
the cells and takes in carbon
dioxide water and waste. The
blood that no longer contains
oxygen and nutrients then goes
back to the heart through veins.
Veins carry waste products away
from cells and bring blood back
to the heart which pumps it to
the lungs to pick up oxygen and
throw away bad carbon dioxide.
Vocabulary
•Arties- Blood vessel that carries blood away
from the heart and has thick elastic walls made
of connective tissue and smooth muscle tissue.
 •Aorta- Branches into smaller arteries, which
then branch into even smaller vessels that travel
all over the body.
 •Capillaries- Are found in body tissue
 •Hypertension- Elevation of the blood pressure;
the diastolic pressure

My Paraphrase
The circulatory system is you
body’s transport it has a lot of
organs. Blood and oxygen go
though the circulatory system. It
also throws away waste and bad
carbon dioxide.
Key Question: why is this system
important to the body? (3 reasons )
Kamilla A.
1.) The circulatory system
is important because it
pumps blood throughout
the body.
2.) The human circulatory
system has three main
parts. The heart, the blood
vessels, & the blood.
3.) It’s important because
the heart is what’s keeping
us alive. Its pumping blood
through out blood vessels
into all other organs
Vocabulary
Heart-The chambered muscular
organ in vertebrates that pumps
blood received from the veins into
the arteries, thereby maintaining
the flow of blood through the
entire circulatory system.
Key Question: What are 3 common
diseases or disorders of this system?
Skander A.
Diseases and Disorders are
important to this system
because it can be damaged. A
common disease of the
system is arteriosclerosis.
Blood clots develop in
affected vessels. These clots
can give heart attacks or
strokes. Hypertension makes
the heart work harder and
can lead to heart attacks,
strokes or kidney failure.
Another common disease is
Cardiovascular. If you get
cardiovascular your heart
will be affected.
Vocabulary
Hypertension- elevation of the
blood pressure; the diastolic
pressure
Paraphrase
If we get a diseases or disorder in our
system we can be very damaged or
ill. We can get hypertension and get
heart attacks or strokes.
Key Question: What are the parts of
this system and what are their jobs?
Tiella G.
My Information- The
circulatory system is
composed of vessels and
muscles that control
the flow of blood
around the body. This
process of blood flowing
around the body is
called circulation. The
main components of the
circulatory system are
the heart, arteries,
capillaries and the
veins.


Atriums-heart beat
Ventricles- 2 lower chambers
Artery- blood vessel
Vein- carries blood
Capillary- connects artery and vein
Plasma- liquid part of blood
Hemoglobin- chemical in red blood cells
Platelet- body form in life cycle
Pulmonary circulation- flow of blood
Systemic Circulation- biggest part of the
system
Coronary Circulation- forms a tissue in heart.
My Paraphrase
My paraphrase- I chose this
key question because I
wanted to learn more
about the body and what it
does to affect in your
body. These parts and jobs
have information about
the Circulatory System.
Ex: Vein carries blood
