ventricle (belly or pouch)
ventricul/o
-
upper right and left chamber of the heart
atrium
-
membrane lining the cavities of the heart
endocardium
-
membrane forming the outer layer of the heart
epicardium
-
partition between the right and left atrium
interatrial septum
-
partition between the right and left ventricle
interventricular septum
-
-
protective sac encolsing the heart; composed of two layers with fluid between
pericardium
-
outer layer of the pericardium
parietal pericardium
-
layer colsest to the heart (of pericardium)
visceral pericardium
-
fluid-filled cavity between the paricardial layers
pericardial cavity
-
lower right and left chambers of the heart
ventricle
-
structures that open and close, regulating one way flow of blood
heart valves
-
heart valve between the left ventricle and the aorta
aortic valve
-
heart valve between the left atrium and left ventricle
bicuspid/mitral valve
-
heart valve opening from the right ventricle to the pulmonary artery
pulmonary semilunar valve
-
valve between the right atrium and the right ventricle
tricuspid
-
valves located at intervals within the lining of veins, esp legs
valves of the veins
-
vessels that carry blood away from the heart to the arterioles
arteries
-
large artery that is the main trunk of the arterial system branching from the left ventricle
aorta
-
small vessels that receive blood from arteries
arterioles
-
tiny vessels that join arterioles and venues
capillaries
-
small vessels that gather blood from capillaroes into the veins
venules
-
vessels tht carry blood to the heart from the venules
veins
-
circulation of the blood throughout the body-delivering oxygen and nutrients to tissues.
systemic circulation
-
circulation of blood through the coronary blood vessels, delivering oxygen and nutrients to the heart
coronary circulation
-
circulation of blood from pulmonary artery through lungs and back to heart thry pulmonary vein; gas exchange
pulmonary circulation
-
period of expansion, blood enters relaxed ventricles from atria
diastole
-
period of contraction, blood is ejected through the aorta and pulmonary arteries
systole
-
normal blood pressure
normotension
-
low blood pressure
hypotension
-
high blood pressure
hypertension
-
sinoatrial node (SA node)
- the pacemaker, in right atrium, initiates electrical conduction of the heart
- causes atria to contract and fire conduction impulses to the AV node
-
atrioventricular node (AV node)
neurological tissue at the center of heart; receives and amplifies the conduction impulses sent down from the SA node, the AV node sends this impulse to the Bundle of His
-
bundle of His
neurological fibers, extend from AV node to the His branches, then to the Purkinje fibers.
-
Purkinje fibers
fibers in the ventricles that transmit impulses to the R and L ventricles-causing them to contract.
-
normal sinus rhythm (NSR)
regular rhythm of the heart cycle-stimulated by the SA node (60-100 bpm)
