Cardiovascular System

By: Madison, Tori, and Isaac

Basic Cardiovascular Duties

The heart is in charge of pumping blood throughout the blood vessels in the body. The heart is protected by a protective sac called the pericardium. This organ requires the most oxygen of any organ in the human body. A heart receives approximately one hundred gallons of blood each day.

Layers and Chambers of the Heat

~The heart has three layers:

- Endocardium: Inner layer

- Myocardium: Middle layer of muscle

- Epicardium: Outer layer

~The heart has two chambers:

- Upper chamber: Right and left atria

- Lower chamber: Right and left ventricles

Stucture of the Cardiovascular System

~ There are different parts of the heart:

- Arteries: Carry blood, with no oxygen, away.

- Veins: Carry blood, with oxygen, to the heart.

- Valves: Bicuspid, tricuspid, pulmonary, and aortic valves.

- Valves prevent back flow and controls the flow.

Heart Dieseases

Bradycardia - Slow heart

Carditis - Inflammation of the heart

Myocarditis - Inflammation of the muscle of the heart

Cardiac Arrest - Heart failure

Cardiomyopathy - Disease in the muscle layer of the heart

Heart Failure - The heart stops beating
