ventricul/o
A

22
Q
atrium
A
upper right or left chamber of the heart
23
Q
endocardium
A
membrane lining the cavities of the heart
24
Q
epicardium
A
membrane forming the outer layer of the heart
25
interatrial septum
partition between the right and left atria
26
interventricular septum
partition between the right and left ventricles
27
pericardium
protective sac enclosing the heart; composed of two layers with fluid in between
28
visceral pericardium
layer of the pericardium closest to the heart (visceral = pertaining to organ)
29
parietal pericardium
outer layer of the pericardium (parietal = pertaining to wall)
30
pericardial cavity
fluid-filled cavity between the pericardial layers
31
ventricle
lower right or left chamber of the heart
32
heart valves
structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood
33
aortic valve
heart valve between the left ventricle and the aorta
34
mitral valve, bicuspid valve
heart valve between the left atrium and left ventricle (cuspis = point)
35
pulmonary semilunar valve
heart valve opening from the right ventricle to the pulmonary artery (luna = moon)
36
tricuspid valve
valve between the right atrium and right ventricle
37
arteries
vessels that carry blood from the heart to the arterioles
38
aorta
large artery that is the main trunk of the arterial system branching from the left ventricle
39
arterioles
small vessels that receive blood from the arteries
40
capillaries
tiny vessels that join arterioles and venules
41
venules
small vessels that gather blood from the capillaries into the veins
42
veins
vessels that carry blood back to the heart from the venules
43
diastole
to expand; period during the cardiac cycle when blood enters the relaxed ventricles from the atria
44
systole
to contract; period during the cardiac cycle when the heart is in contraction and blood is ejected through the aorta and the pulmonary artery
45
normotension
normal blood pressure
46
hypotension
low blood pressure
47
hypertension (HTN)
high blood pressure
48
angina pectoris
chest pain caused by a temporary loss of oxygenated blood to the heart muscle; often caused by narrowing of the coronary arteries (angina = to choke)
49
arteriosclerosis
thickening, loss of elasticity, and calcification (hardening) of arterial walls
50
fibrillation
chaotic, irregular contractions of the heart, as in atrial or ventricular fibrillation
