| Question | Answer |
|---|---|
| Describe capillaries | Join arterial system with venous system Most significant Provide cells with vital products |
| Describe the heart | hollow, muscular organ that pumps blood through the arteries, capillaries and veins. Lying in the mediastinum that propels blood to entire body |
| Describe the SA node | Located in 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 to the heart | Skeletal muscle contraction Gravity Respiratory activity Valves |
| How is blood supplied to the heart muscle? | Coronary arteries |
| Name the factors that influence blood pressure | Resistance of blood flow Pumping action of heart Viscosity of blood Elasticity of arteries Quantity of blood |
| Name the four structures responsible for electrical conduction of the heart | SA node AV node bundle of His Purine fibers |
| Name the three layers of the heart | Endocardium Myocardium Epicardium |
| What are the three layers of artery walls | Tunica externa Tunica media Tunica intima |
| What are the three major types of blood vessels | Arteries Capillaries Veins |
| What are the valves | Small structures within veins that prevent back flow of blood |
| What is endocarditis | Inflammation of the inner lining of the heart and it's valves |
| What type of blood do arteries carry | Oxygenated |
| What type of blood do veins carry | Deoxygenated |
| Tricuspid | Right ventricle and right atrium |
| Any endovascular procedure that reopens narrowed blood vessel | angioplasty |
