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
