Cardiovascular 22
Test review for the Cardiovascular System
Question | Answer |
---|---|
Angina | A severe, often constricting pain affecting the chest region, caused by lack of oxygen to the heart cells |
Arrhythmia | Irregular rhythm of the heart |
Coagulation | To solidify or change from a fluid state to a solid state *blood clot formation |
Congestive Heart Failure | Accumulation of blood in the ciculatory system caused by the inability of the heart to pump efficiently |
Coronary Artery Disease | A common term used for several diseases the affect the heart |
Diuretic | An agent that increases urine output and dieresis |
Enzyme | A protien that speeds up a reaction by reducing to amount of energy required to initiate a reaction; *biological catalyst |
Hyperlipidemia | High concentration of lipids in the circulatory system |
Hypertension | High Blood Pressure |
Hypotension | Low Blood Pressure |
Myocardial Infarction | Death of a heart muscle |
Stroke | Impaired cerebral blood flow causes thrombosis, hemorrhage, or embolism |
Thromin | An enzyme that is formed in coagulating blood from prothrombin; reacts with fibrinogen which is essential in the formation of blood clots |
Thrombolytic | Medications used to break up a thrombus or a blood clot |
Endocardium | Smooth accordion pleat-like surface that allows the heart walls to collapse |
Myocardium | Heart muscle that contracts |
Epicardium | Outter layer of the heart; inner layer of the pericardium |
Systole | Myocardium squeezes blood from the heart chamber into the pulmonary artery or aorta |
Diastole | Blood is allowed to refill the chambers (relaxation) |
Arteriosclerosis | Disease od the arterial vessels resulting from thickening, hardening, and loss of elasticity in the arterial walls |
Atherosclerosis | Form of arteriosclerosis resulting from cholesterol-lipid calcium deposits in the walls of arteries |
Prehypertensive State | Blood pressure of 120/80 mm Hg to 140/90 mm Hg |
Transient Ischemic Attacks | Short duration of a reduction of oxygen to the brain and are caused by atherosclerotic cerebrovascular disease |
Bile Acid Squestrants | Increase the loss of cholesterol, especially LDL |
HMG-COA Reductase Inhibitors | Raise HDL and lower LDL |
Antarrhythmics | Induce regular heartbeats |
Cardiac Glycosides | Increase forcefulness of the pumping of the heart |
Thiazide / Thiazide like agents | Increase urinary excretion |
Loop Diuretics | Cause large amounts of urine to be excreted |
Potassium-Sparing | Eliminate urine by interruptin the sodium reabsorption |
Carbonic Anhydrase | Inhibit hydrogen secretion by the renal tubule, causing loss of potassium and sodium |
Osmotic Diuretics | Eliminate water weight by increasing the osmolarity of the glomerular filtrate |
Calcium Channel Blockers | Decrease calcium intake by the heart and blood vessels |
Angiotensin-Converting Enzymes Agents | Cause a decrease of pressure in the arteries |
Angiotensin II Receptor Agents | Inhibit effects of angiotensin II receptors in vascular muscles |
Beta-Blocking Agents | Block various enzymes, such as epinephrine, that cause high blood pressure |
Nitrates | Dilate the arteries to permit an increase of blood flow through the heart muscle |
Anticoagulants | Converts blood-clotting fibrin into another substance |
Thrombolytics | Dissolve blood clots |
