Exam Review- Cardiovascular

Capillaries join arterial system to venous stem, most significant, provide cells with vital products and remove waste products from cells
Heart hollow muscular organ lying in the mediastinum that propels blood to the entire body
SA Node located in the upper portion of right atrium, has built in rhythm, initiates and transmits each heart beat, sets basic pace for cardiac rate
How do veins return blood? skeletal muscle contraction, gravity, respitory activity, valves
How is blood supplied to the heart muscle coronary arteries
Five factors the influence blood pressure 1. resistance of blood flow. 2. pumping action of heart. 3. viscosity of blood. 4. elasticity of arteries. 5. quality of blood
Four structures responsible for electrical conduction of the heart 1. SA node 2. AV node. 3. bundle of His. 4. Purkinje Fibers
3 Layers of the heart 1. Epicardium-outer. 2. Myocardium-middle 3. Endocardium-inner
3 Layers of artery walls 1. tunica externa 2. tunica media 3. tunica intima
3 major type of blood vessels 1. arteries 2. capillaries 3. veins
What are valves small structures within veins that prevent backflow of blood (regurgitation)
What is endocarditis inflammation of the inner lining of the heart and its valves
Type of blood carried by arteries oxygenated (except for pulmonary artery)
Type of blood carried by veins deoxygenated (except for pulmonary veins)
What are the 4 heart valves 1. tricuspid 2. bicuspid (mitral) 3. pulmonic 4. aortic
Where is the tricuspid valve located right ventricle and right atrium
Where is the mitral valve located left atrium and left ventricle
Where is the pulmonic valve located pulmonary artery and right ventricle
Where is the aortic valve located aorta and left ventricle
