Match the following terms
Upper right portion & the broadest part of the heart; where great vessels enter and leave
base

apex
membranous fibroserous sac enclosing the heart and the bases of the great vessels
pericardium
loose fitting sac of strong connective tissue- is the outermost layer
fibrous pericardium
serous pericardium
Consists of two layers, covers the heart's surface

serous pericardium
layer of the serous pericardium that lines the inside of the fibrous pericardium
parietal layer
visceral layer
layer of the serous pericardium that covers the heart's surface
parietal layer
visceral layer
This cavity contains a small amount of serous fluid, which helps prevent friction as the heart beats
pericardial cavity
Thoracic cavity
Ventricular cavity
Abdominal cavity
Also known as the the visceral layer of the serous pericardium, this layer of the heart consists of a thin layer of squamous epithelial cells
epicardium
myocardium
endocardium
middle layer of the heart that is the thickest of the three layers and performs the work of the heart; composed of cardiac muscle
myocardium
endocardium
epicardium
Lines the hearts chambers, covers the valves, and continues into the vessels. consists of a thin layer of squamous epithelial cells. very smooth to help keep blood from clotting as it fills the heart's chambers
endocardium
myocardium
epicardium
The two upper chambers of the heart that serve as reservoirs, receiving blood from the body or lungs.
atrium
Ventricles
The two lower chambers that serve as pumps, receiving blood from the atria and then pumping it either to the lungs(right ventricle) or the body (left ventricle)
ventricles
atria
the right and left atria are separated by this common wall of
Interatrial septum
Intraventricular septum
The right and left ventricles are separated by this common wall
interventricular septum
interatrial septum
The (a) serve as reservoirs, (b) blood from the body or lungs; they are separated by the (c) septum. The (d) receive blood from the atria and pump it to the lungs or the body; they are separated by the (e) septum.
The portion of the heart wall that lines the heart's chambers is the
myocardium
pericardium
endocardium
epicardium
Select all that are considered the Great vessels
superior and inferior vena
pulmonary artery
four pulmonary veins
aorta
mitral valve
strands of fibrous connective tissue that connect the edges of the AV valves to the papillary muscles
chordae tendineae
ligaments
sinews
Muscles located in the ventricles that attach to the cusps of the atrioventricular valves. They contract with the ventricles, pulling on the chordae tendineae and anchoring the valve cusps in
papillary muscles
Chordae tendineae
Tricuspid valve
Atrioventricular septum
To ensure that blood moves in a forward direction through the heart, the heart contains four valves: one between each atrium and its ventricle and another at the exit of each ventricle.
true
false
The valves that regulate flow between the atria and the ventricles
atrioventricular valves
(AV)
semilunar valves
The valves that regulate flow between the ventricles and the great arteries
atrioventricular valves (AV)
semilunar valves
The right AV valve- also called the (a) valve- prevents backflow from the (b) ventricle to the right (c) . The left AV valve-also called the (d) valve-prevents backflow from the (e) ventricle to the left atrium.
The (a) valve prevents backflow from the pulmonary (b) to the (c) ventricle. The (d) valve prevents backflow from the (e) to the left ventricle.
semi rigid fibrous connective tissue encircling each heart valve. It also provides insulation between the atria and the ventricles, preventing electrical impulses from reaching the ventricles other than through a normal conduction pathway.
skeleton of the heart
A type of muscle tissue found in the heart
A type of tissue that helps to regulate blood flow
A type of tissue that helps to support the heart
Valves open and close in response to pressure changes within the heart
true
false
Match the following valves with their function
prevents backflow from the pulmonary artery to the right ventricle
pulmonary valve
prevents backflow from the aorta to the left ventricle
aortic valve
prevents backflow from the right ventricle to the right atrium
tricuspid valve
prevents backflow from the left ventricle to the left atrium
mitral valve
The point of maximum impulse of the heart is at
mediastinum
base
apex
aorta
Which heart valve controls the flow of blood between the left atrium and the left ventricle?
pulmonary valve
aortic valve
tricuspid
Mitral valve
What is the name of the great vessel that supplies blood to the right atrium
superior and inferior vena cavae
aorta
pulmonary artery
pulmonary veins
The heart has its own vascular system, know as the coronary circulation, to keep it well supplied with oxygenated blood.
true
false
large transverse vein on the heart's posterior that returns blood to the right atrium
coronary sinus
these deliver oxygenated blood to the myocardium
coronary arteries
these collect the deoxygenated blood
cardiac veins
supplies blood to the right atrium, part of the let atrium, most of the right ventricle, and the inferior part of the left ventricle
right coronary artery
supplies blood to the lest atrium, most of the left ventricle, and most of the interventricular septum
left coronary artery
A blockage of which artery is sometimes called the "widow maker"
left coronary artery
right coronary artery
The most abundant blood supply goes to the (a) of the (b) (c) . Because the left ventricle does most of the work and needs more (d) and nutrients than the rest of the myocardium.
The left coronary artery branches into which two arteries?
anterior descending artery
circumflex arteries
aorta
pulmonary
Cardiac muscle is striated just as skeletal muscle is.
true
false
