HAVE A HEART
Veterinary Medical Terminology Chapter 8
| Question | Answer |
|---|---|
| cardiovascular | pertaining to the heart and blood vessels |
| cardi/o | heart |
| mediastinum | contains the large blood vessels, trachea, esophagus, lymph nodes, and other structures |
| pericardium | double-walled membrane that surrounds the heart |
| pericardial fluid | fluid within the pericardial space that prevents friction between the heart and pericardium membrane when the heart beats |
| epi- | upper |
| epicardium | external layer of the heart |
| myocardium | middle layer of the heart-thickest-actual heart muscle |
| endocardium | inner layer of the heart |
| endo- | within |
| coron/o | crown |
| ischemia | deficiency in blood supply to an area |
| necrosis | tissue death |
| atri/o | atria |
| septum | separating wall or partition |
| ventricles | caudoventral chambers of the heart |
| interventricular septum | wall that separates the ventricles |
| apex | narrow tip of the heart |
| valve | membranous fold in the heart such as the mitral valve |
| valv/o or valvul/o | valve |
| arrhythmia | abnormal rhythm |
| dysrhythmia | abnormal rhythm |
| systole | means contraction |
| diastole | means expansion |
| auscultation | act of listening to a body sound using a stethoscope |
| stetho- | chest |
| -scope | instrument to visually examine or monitor |
| pan- | all |
| heart murmur | abnormal sound associated with the turbulent flow of blood |
| stenosis | narrowing |
| angi/o or vas/o | vessel |
| artery | blood vessel that carries blood away from the heart |
| arteri/o | artery |
| aorta | main trunk of the arterial system that begins from the left ventricle of the heart |
| arterioles | smaller brances of arteries |
| arter/i | vessel that carries blood away from the heart |
| -ole | small |
| perfusion | blood flow through tissues |
| capillary refill time, CRT | indicator of blood perfusion; apply pressure to mm and pink color should return to pink by 2 seconds or less |
| veins | returns blood to the heart |
| ven/o or phleb/o | vein |
| blood pressure | tension exerted by blood on the arterial walls |
| pulse | rhythmic expansion and contraction of an artery produced by pressure |
| sphygmomanometer | measure blood pressure by measuring the amount of pressure exerted against the walls of the vessels |
| sphygm/o | pulse |
| man/o | pressure |
| -meter | device |
| tensi/o | pressure or tension and is used when describing blood pressure |
| ech/o | sound |
| ather/o | plaque or fatty substance |
| plaque | patch or raised area |
| cardiomegaly | heart enlargement |
| congestion | accumulation of fluid |
| edema | accumulation of fluid in intercellular spaces |
| ascites | fluid accumulation in the pertoneal cavity |
| pulmon/o | lung |
| dirofilariosis | heartworm infection |
| prophylaxis | prevention |
| hematoma | collection of blood |
| hypoxia | below normal levels of oxygne |
| BP | blood pressure |
| CRT | capillary refill time |
| CHF | congestive heart failure |
| CPR | cardiopulmonary resuscitation |
| HR | heartrate |
| MM | mucous membrane |
| idiopathic | unknown cause |
| iatrogenic | produced by treatment |
| What are the two divisions of the circulatory system? | systemic and pulmonary |
| What is systemic circulation? | blood flow to all parts of the body except the lungs |
| What is pulmonary circulation? | blood flow out of the heart through the lungs and back to the heart |
| What is another name for the mitral valve? | bicuspid |
| What is another name for the right atrioventricular valve? | tricuspid |
| Which valve controls the opening between the right atrium and the right ventricle? | tricuspid or right atrioventricular |
| Which valve controls the opening between the right ventricle and the pulmonary artery and controls blood entering the lungs? | pulmonary semilunar |
| Which valve controls the opening between the left atrium and left ventricle? | mitral or left atrioventricular valve |
| Which valve controls the opening between the left ventricle and the aorta and controls blood entering the arterial system? | aortic semilunar valve or aortic valve |
| Where is the sinoatrial node found? | in the wall of the right atrium near the entrance of the superior vena cava |
| What is the purpose of the sinoatrial node? | establishes the basic rhythm of the heart and is sometimes called the pacemaker |
| What is the instrument called used to listen to body sounds? | stethoscope |
| What can cause regurgitation in the cardiovascular system? | heart valves not closing correctly |
