The inner most layer of the heart. It forms the lining and folds
back onto itself to form the 4 valves. It is in this layer that the
conduction system is found - Answer: endocardium
The middle and contractile layer of the heart. It is made up of
striated m fibers interspersed with intercalated disks. - Answer:
Myocardium
The outermost layer of the heart. It is actually the inner (viseral)
layer of the pericardium. - Answer: Epicardium
Is a sac in which the heart is contained. It consists of the
outermost fibrous pericardium and the serous pericardium
which consists of a visceral and parietal portion. The visceral
layer invests the heart and is also called the epicardium. The
parietal layers lines the fibrous pericardium. Between the
visceral and parietal layers is a serous fluid which serves to
prevent friction as the heart beats. - Answer: The Pericardium
Receives deoxygenated blood returning to the heart from the
,body via the superior vena cava which carries blood from the
upper body and the inferior vena cava which carries blood from
the lower body - Answer: Right Atrium
Receives deoxygenated blood from the right atrium which is
pumps to the lungs fro oxygenation through the pulmonary
artery (trunk) to the right and left pulmonary arteries - Answer:
Right Ventricle
The only arteries in the body that carry deoxygenated blood. -
Answer: The Pulmonary Arteries
Receives oxygenated blood returning from the lungs via the
right and left pulmonary veins. - Answer: Left Atrium
Are the only veins in the body that carry oxygenated blood -
Answer: The pulmonary veins
Receives the oxygenated blood from the left atrium and pumps
it to the body through the aorta, the largest artery of the body -
Answer: Left Ventricle
A 2- sided separated by a septum. The upper chambers consist
of the right and left atria, the lower chambers are the right and
left ventricles. The chambers pump simultaneously - both atria
contract together, then the two ventricles. - Answer: The heart
,is actually ...
The purpose of the heart valves is to prevent back-flow of blood
thereby assuring uni-directional flow thru the heart - Answer:
The Heart Valves
So-called because they are located between the atria and the
ventricles - Answer: The atrioventricular valves (AV)
Located between the right atrium and the right ventricle. As the
name connotes, it has three cusps. - Answer: Tricuspid valve
Located between the left atrium and the left ventricle. It has two
cusps and its also called the bicuspid valve - Answer: Mitral valve
They have half-moon shaped cusps - Answer: The semilunar
valves
Located between the right ventricle and the pulmonary trunk -
Answer: Pulmonic valve
Located between the left ventricle and aorta - Answer: Aortic
valve
, Are caused by diseases of the valves or other structural
abnormalities - Answer: Heart murmurs
The first heart sound is due to the closure of the mitral and
tricuspid valves - Answer: S1
Second heart sound is due to the closure of the aortic and
pulmonic valves - Answer: S2
The arteries supplying the heart are the right and left coronary
from the aorta. The veins accompany the arteries, and
terminate in the right atrium. - Answer: Vessels of the heart
Which is subdivided into the sympathetic and parasympathetic
nervous system - Answer: The heart is influenced by the
Autonomic Nervous System (ANS)
Affects both the atria and the ventricles by increasing heart rate,
conduction and irritability - Answer: Sympathetic nervous
system
Affects the atria only by decreasing heart rate, conduction and
irritability - Answer: Parasympathetic Nervous System
This is the ability of the cardiac pacemaker cells to
