Cardiovascular Concept Map

Major functions of the cardiovascular system

Anatomy of Heart

Layers of Heart

Blood Flow through heart and body

Major arteries and veins of body

Aorta

Arteries- Carries blood away from heart

Arterioles- found between arteries and capillaries

Venules- Connects capillaries and veins

Veins- return blood toward heart

Tunica intima- inner lining of blood vessels

Tunica media- middle smooth muscle layer

Tunica externa- outermost fibrous connective tissue

Internal control of heart rate

heart muscles cells contract without nerve impulses in a regular continuous way

elements of intrinsic conduction system: Sa node> av node> av bundle> bundle branches> purkinje fubers> ventriculkar wall>

Events of one complete heart beat

atria contract simultaneously

atria relax then ventricles contract together then relax

Pericarditis: inflammation of pericardium

Angina pectoris: crushing chest pain form lack of blood

Myocardial infarction: heart muscle cells die due to lack of blood to heart muscles

mumur: abnormal or irregular heart sounds can be caused by valve stenosis

valve stenosis: defect in valves failing to open which makes heart pump harder

valve stenosis: defect in valves failing to open which makes heart of pump harder

filbrillation: rapid uncoordinated shuddering of heart muscle which prevents heart from acting as a pump

varicose veins: swollen and twisted veins caused by when valves in veins do not work and cause back flow or pooling of blood

transport of nutrients oxygen and hormones

the removal of metabolic wastes such as carbon dioxide and nitrogenous wastes
