1. The Cardio Vascular System By Mason Shoalmire

2. Organs • The Cardio Vascular body system also called the circulatory system is one of the most vital. The organs include the heart, the blood, and the blood vessels. The heart is the pump. It pumps the blood which contains nutrients throughout the body using the blood vessels.

3. The Heart • The heart is an utterly unique organ containing four chambers used to pump blood throughout the body. The right atrium receives blood and pumps it to the right ventricle which pumps the blood to the lungs were it receives oxygen. The right ventricle the pumps it to the left atrium after receiving blood it pumps it to the left ventricle (the strongest chamber) that pumps the oxygenated blood throughout the body.

4. The Blood Vessels • The blood vessels are the train tracks of the body. They transport nutrients, oxygen, and waste the body. There are three types of blood vessels. 1-Veins move blood back to the heart. 2-Arteries move blood to the body were it is needed. 3- Capillaries move blood to individual cells, sometimes being only one cell thick. Some of the most important are the Aorta, the superior and inferior vena cava, and the pulmonary vein and arteries.

5. The Blood • There are several different components that make up the blood. The plasma makes up about one half of the blood it also contains the nutrients and glucose, it is even the transport system other blood cells use. The red blood cells give it its color and is used to transport oxygen to cells and carbon dioxide back to the lungs to expel it. The white blood cells defend your body from pathogens. They destroy them by either eating or creating anti bodies to overpower it. The last cell that makes up the blood is the platelets. The platelets are used to clot up breaks in the blood stream. All of the blood cells are created in the bone marrow.

6. Interactions • The circulatory system interacts with several systems very closely, mainly the repertory, the skeletal, and the excretory systems. The skeletal system produces the components of the blood. The repertory system replenishes the oxygen in the blood and expels the carbon dioxide. The excretory system expels other types of waste like excess water and salt that it reeves from the blood stream.

7. Facts • The red blood cells use their indention to squeeze through tight capillaries. • Pathogens use have several methods for beating the white blood cells, such as changing there protein make up to become resistant to anti bodies the body creates. • The heart uses one way valves to stop back-ups in the heart otherwise the body would fall into cardiac-arrest. • The cells in the heart are one of a kind even the individual cells are constantly contracting.

8. Cardio Vascular Problems • Cardiac Arrest- Cardiac arrest is one of the worst problems in the body often causing death. It happens when there is an irregular beat or the heart completely stops. It has many causes including chest trauma, heart infection, blocked blood vessels, defective valves, and drugs. • Sickle Cell Anemia- Sickle Cell Anemia is the genetic disorder that cause re blood cells to form in shape of a sickle(crescent). It is a very serious disease that can cause many problems throughout the body like restricting blood flow to organs. • There are numerous other problem that can occur with this body system many of which are life threatening.
