FACTS• The Circulatory system moves food and oxygen around

to where you need it and it gets rid of waste.• The average sized adult carries about 5L of blood.• If you were to lay out all of your arteries, veins and

capillaries of one adult it would stretch about 60,000 miles.

• If you put your Circulatory system on a straight line it would orbit around the Earth two and a half times.

• It delivers Hormones from there glands to their target organs.

Important Roles in Humans The Circulatory System is called the body’s delivery system because it delivers nutrients and oxygen. The oxygen and nutrients are used to fuel the tissues and organs of the body.

Levels of Organization

Circulatory System

Heart (organ)

Cardiac Muscle Tissue (tissue)

Cardiac Myocyte (cell)

Levels of Organization• In the Circulatory System I chose the organ, the heart.

Cardiac muscle tissue is found in the heart. The heart is the only organ in the human body that cardiac muscle tissue is found in. Cardiac Myocyte are the cells that make up cardiac muscle tissue.

Major Organs in Our System • The major organ

in our system is the

heart. Our system is

centered around the

heart and the heart

pumps blood around

a complex networks

of arteries and veins.

The heart pumps

blood to every part of

the body.

Professions that work with the system• Cardiovascular Anesthesiologist

They are doctors that give medicines and anesthetics used during heart surgery. They study the effects of the medicines to learn how to best protect the heart and organs of which they are operating on. The cardiovascular anesthesiologist stays in the operating room during the surgery is taking place. He or she makes the decisions about how to protect the organs and they monitors how the patients wake up from anesthesia.

Professions that work with the system Cardiovascular Surgeon

The cardiovascular surgeon operates

on the heart and blood vessels. They

repair damage caused by heart

diseases or disorders. Cardiovascular

surgeons work in hospitals and they

preform many operations such as heart transplants, heart valve repair and replacements and transmyocardial laser revascularization.

How our System is Connected to Two (2) Others

After blood returns to the

heart from around the body, the

blood travels to the lungs to replenish

with oxygen. From your lungs it

goes to the other side of your heart

and then to all parts of the body.

Therefore the circulatory system is

connected to the respiratory system.

How our System is Connected to Two (2) Others

When exercising, your

heart beats faster so it can pump

more blood to your muscles to

function better. That helps you

move faster or jump higher.

Therefore, the circulatory system

is connected to the muscular

system.

Maintain a Healthy System

Maintain healthy systems is very important. To maintain a healthy circulatory system you can get plenty of exercise. You can also eat a healthy diet to maintain a healthy weight. Also, you should see a doctor regularly for annual checkups.

High Cholesterol (arteriosclerosis)

Cholesterol floating in your blood stream begins to block your arteries and veins so oxygen and nutrients can’t travel smoothly. If not enough blood gets though, it could lead to a heart attack or a stroke.

Usually there is no cure for high

cholesterol but to prevent it you

can have a healthy diet, exercise

and don’t smoke. If you have

arteriosclerosis you have to take

medication for life.

2 Common Diseases or Disorders that Affect our System

2 Common Diseases or Disorder that Affect our System

Heart Failure

There are many causes for heart failure including coronary artery disease, cardiomyopathy, congenital heart disease, heart valve disease, abnormal heart rhythms. Heart failure occurs when the heart doesn’t pump properly. There is no cure for heart failure and you

have a shortage of breath and lack

of energy. There is treatment as

well as medication. Sometimes, you

can have surgery or a heart

transplant.

How Organs Work Together

The heart pumps blood through a series of blood vessels throughout the body. The blood contains oxygen that it picks up from the lungs and nutrients absorbed from the digestive system. It carries the blood out to the tissues throughout the body to be used for energy. Once the oxygen is distributed and used up by the muscles,

the blood travels back to the heart and

lungs, to start to all over again. Along

the way, the blood goes through the liver

and kidneys to remove waste.
