The document provides information about the circulatory system. It explains that the circulatory system is responsible for transporting nutrients, water, oxygen, and waste throughout the body using the heart, blood vessels, and blood. The heart pumps blood through a network of arteries, veins, and capillaries. Arteries carry oxygenated blood away from the heart while veins carry deoxygenated blood back to the heart. Capillaries allow for the exchange of gases, water, and nutrients between blood and body tissues. The document also describes the components and functions of the heart and blood in more detail.

5. What is the job of the Circulatory System?
The Circulatory System is responsible for transporting
materials throughout the entire body. It transports
nutrients, water, and oxygen to your billions of body
cells and carries away wastes such as carbon dioxide
that body cells produce. It is an amazing highway that
travels through your entire body connecting all your
body cells. The following are the three major parts of
the circulatory system, with their roles:
1. Heart –pumps the blood throughout the body
2. Blood vessel –carries the blood throughout the body
 Arteries - carry oxygenated blood away from the
heart to the cells,
tissues and organs of the body.
 Veins- carry deoxygenated blood to the heart
 Capillaries - the smallest blood vessels in the
body, connecting the
smallest arteries to the smallest veins.
- the actual site where gases and nutrients
are exchanged
3. Blood –carries the materials throughout the body
The Heart
The Heart is an amazing organ. The heart beats about 3
BILLIONtimes during an average lifetime. It is a muscle
about the size of your fist. The heart is located in the
center of your chest slightly to the left. Its job is to
pump your blood and keep the blood moving
throughout your body.

6. The Blood
The blood is an amazing substance that is constantly flowing
through our bodies.
 Your blood is pumped by your heart.
 Your blood travels through thousands of miles of blood
vessels right within your own body.
 Your blood carries nutrients, water, oxygen and waste
products to and from your body cells.
 A young person has about a gallon of blood. An adult has
about 5 quarts.
 Your blood is not just a red liquid but rather is made up of
liquids, solids and small amounts of oxygen and carbon
dioxide.
The Blood Vessels
In class we talked about three types of blood vessels:
 Arteries
 Capillaries
 Veins
Arteries
 Arteries are blood vessels that carry oxygen rich blood AWAY
from the heart. Remember, A A Arteries Away, A A Arteries
Away, A A Arteries Away.
Capillaries
 Capillaries are tiny blood vessels as thin or thinner than the
hairs on your head. Capillaries connect arteries to veins. Food
substances (nutrients), oxygen and wastes pass in and out of
your blood through the capillary walls.
Veins
 Veins carry blood back toward your heart.

7. Let’s now have the different types of
circulation. We have 3 types and they are
Pulmonary Circulation, Coronary Circulation and
Systemic Circulation.
Pulmonary Circulation
Movement of blood from
the heart, to the lungs, and
back to the heart.
Coronary Circulation
Movement of blood
through the tissues of the
heart.
Systemic Circulation
Movement of blood from
the heart to the rest of the
body, excluding the
lungs.

8. The heart has four chambers: two atria and two
ventricles.
The right atrium receives oxygen-poor blood from the
body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the
lungs.
The left atrium receives oxygen-rich blood from the
lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the
body.

9. RESPIRATO
RY
SYSTEM

10. What is the respiratorysystem?
Your respiratorysystemis made up of
the organs in your body that help youto
breathe. Remember,that Respiration=
Breathing. The goal of breathingis to
deliver oxygento the body and to take
away carbondioxide.
Parts of the respiratorysystem
Lungs
The lungs are the mainorgans ofthe
respiratory system.Inthe lungs oxygenis
taken into the body and carbondioxide is
breathedout. The redbloodcells are
responsible for pickingup the oxygeninthe
lungs and carryingthe oxygento all the
body cells that need it. The red bloodcells
drop off the oxygento the body cells, then
pickup the carbondioxide whichis a waste
gas product producedby our cells. The red
bloodcells transport the carbondioxide
backto the lungs and we breathe it out
whenwe exhale.

11. Trachea
The trachea (TRAY-kee-uh} is sometimes called the windpipe. The
trachea filters the air we breathe and branches into the bronchi.
Bronchi
The bronchi (BRAHN-ky) are two air tubes that branch off of the
trachea and carry air directly into the lungs.
Diaphragm
Breathing starts with a dome-shaped muscle at the bottom of the
lungs calledthe diaphragm (DY-uh-fram). When you breathe in, the
diaphragm contracts. When it contracts it flattens out and pulls
downward. This movement enlarges the space that the lungs are in. This
larger space pulls air into the lungs.When you breathe out, the
diaphragm expands reducing the amount of space for the lungs and
forcing air out. The diaphragm is the main muscle used in breathing.

21. All animals need to ________________ materials around to the
different parts of their body. This is the job of the ________________
system. The circulatory system consists of a liquid called
_______________, a pump called the ________________ and a series
of vessels called _________________ and ________________.
One thing that must be transported around is a gas called
_____________. Oxygen enters the blood through the
______________. It is then ____________ through the heart and
around the body where it is used along with food to make
______________. The body produces another gas called
_______________, which is a waste product. This gas is carried back to
the heart and then to the lungs where it is released back into the
_______________.
The vessels that transport blood _________ from the heart are called
arteries. The blood in arteries is _____________ red because it is rich in
oxygen. The vessels that transport blood _______________ the heart
are called veins. The blood in veins is ______________ red because it is
low in oxygen. ________________ are small vessels that join the
arteries and veins.
_______________ from food are also transported around the body by
the circulatory system. They enter the blood from the small
_________________. The circulatory system also helps to regulate
temperature by transporting _________________ around the body.

All animals need ________________ to make energy from food. We
get this oxygen from the _____________ that we breathe. In order to
get the oxygen into the blood where it can be transported to the rest
of the body, the air travels through a system of organs called the
_______________ system.
When you ________________, air enters the body through the
_______________ or the ____________. From there it passes through
the ______________, which forces air into the _______________ and
food into the esophagus. The air travels down the trachea into two
branching tubes called ________________ and then on into the
________________.
In the lungs oxygen from the air enters the _______________. At the
same time, the waste gas ____________________ leaves the blood
and then leaves the body when you ___________________. Some
__________________ also leaves the body when you exhale, which is
why mirrors get foggy when you breathe on them. The
______________ is the muscle that controls the lungs.
It is important to keep the respiratory system clear so oxygen can
keep flowing into your body. If something gets in your nose and
irritates it, you ___________________. If something gets in your
trachea or bronchi and irritates it, you _________________. If
something irritates your diaphragm, you _________________. Finally,
if the brain thinks you are not getting enough oxygen, then it forces
you to _________________.
