Key Terms
| Question | Answer |
|---|---|
| Ace Inhibitors | block the renin-angiotensin pathway from the kidneys to decreases blood pressure. |
| Angina Pectoris | chest pain caused by lack of oxygen and nutrients in the heart tissue. |
| Angiotensin receptor blockers (ARBs) | block the action of angiotensin. Prevent angiotensin from attaching to receptors and thus prevent blood vessels from contracting and increasing blood pressure. |
| Anoxia | lack of oxygen |
| Atherosclerosis | Poor heart condtion, fatty plaques in the arteries |
| Hypertension | high blood pressure |
| Cerebrovascular accident (CVA) | sudden death of some brain cells due to lack of oxygen when the blood flow to the brain is impaired by blockage or rupture of an artery to the brain. A CVA is also referred to as a stroke. |
| Congestive Heart Failure | a weakness of the heart that leads to a buildup of fluid in the lungs and surrounding body tissues |
| Contractility | capable of or producing contraction |
| Cyanosis | a bluish tint to the skin |
| hypoxia | reduced oxygen |
| ischemia | an inadequate blood supply to an organ or part of the body, especially the heart muscles that lead to tissue injury. |
| deep vein thrombosis DVT | thrombosis in a vein lying deep below the skin, especially in the legs. |
| Dysrthythmias | abnormality in a physiological rhythm, especially in the activity of the brain or heart |
| Embolus | a blood clot, air bubble, piece of fatty deposit, or other object which has been carried in the bloodstream to lodge in a vessel and cause an embolism. |
| Hemostasis | the stopping of a flow of blood. |
| High density lipoprotein | a lipoprotein that removes cholesterol from the blood and is associated with a reduced risk of atherosclerosis and heart disease |
| Hyperlipemia | an abnormally high concentration of fats or lipids in the blood. |
| infarction | obstruction of the blood supply to an organ or region of tissue, typically by a thrombus or embolus, causing local death of the tissue or death |
| myocardial infarction (MI) | Heart attack |
| Low density lipoprotein (LDL) | the form of lipoprotein in which cholesterol is transported in the blood. |
| Pulmonary circulation | oxygen rich blood is then returned to the heart via pulmonary veins |
| Shock | fall in blood pressure, caused by such events as loss of blood, severe burns, bacterial infection, allergic reaction, or sudden emotional stress, and marked by cold, pallid skin, irregular breathing, rapid pulse, and dilated pupils |
| Thrombus | a blood clot formed in situ within the vascular system of the body and impeding blood flow. |
| Very low density lipoprotein (VDL) | substances that carry fat from the liver to other parts of the body. |
| Cardiovascular system | Heart and Blood Vessels |
| Heart has four Chambers | left and right atrium left and right ventricles |
