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.
