Major functions of the cardio vascular system
Circulates oxygen and removes Carbon Dioxide.
Provides cells with nutrients.
Removes the waste products of metabolism to the excretory organs for disposal.
Protects the body against disease and infection.
Clotting stops bleeding after injury.
Anatomy of the heart (including all chambers, and valves)
Layers of the heart
Myocardium
Endocardium
Endocardium
Blood flow through the heart and body
The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve
The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body
Structural and functional differences between blood vessel types(arteries, veins, capillaries)
Arteries have thick walls composed of three distinct layers
Arteries transport blood away from the heart
Capillaries are very small and will not be easily detected Capillaries surround body cells and tissues to deliver and absorb oxygen, nutrients, and other substances
Veins have thin walls but typically have wider lumen
Veins return blood back toward the heart
Cardiac cycle and the ECG
Disorders of the cardiovascular system
Abnormal heart rhythms, or arrhythmias.
Aorta disease and Marfan syndrome.
Congenital heart disease.
Coronary artery disease (narrowing of the arteries)
Deep vein thrombosis and pulmonary embolism.
Heart attack.
Heart failure.
Heart muscle disease (cardiomyopathy)
Heart attack.
