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

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
