The three layers of the pericardium from superficial to deep
What is fibrous pericardium, parietal pericardium, and visceral pericardium
100
The three ways blood enters the heart
What are the superior vena cava, inferior vena cava, and coronary sinus
100
The plane cut through the heart which would reveal this structure
What is a transverse plane
100
This structure is known as the "pacemaker"
What is the sinoatrial (SA) node
100
Heart contraction is known as this
What is systole
200
The three layers of the heart wall from deep to superficial
What is endocardium, myocardium, and epicardium
200
Pressure from the right atrium opens this valve
What is the right atrioventricular valve/tricuspid valve
200
These two spaces are separated by this structure
What are atria and ventricles
200
This structure holds the electrical impulse for a split second so atria can finish their contraction
What is the atrioventricular (AV) node
200
A heart attack is known as this
What is a myocardial infarction
300
The layer which is made of cardiac muscle
What is the myocardium
300
The right side of the heart is part of this circuit
What is the pulmonary circuit
300
These openings from atria to ventricles are anchored here
What are valves
300
This structure is located within the superior interventricular septum
What is the atrioventricular (AV) bundle/bundle of His
300
The fossa ovalis is located in this structure
What is the interatrial septum
400
These two layers are synonymous
What is epicardium and visceral pericardium
400
These two valves open in response to increased ventricular pressure
What are the semilunar valves (aortic and pulmonary)
400
This structure uses the fibrous skeleton as a tendon
What is cardiac muscle
400
These structures conducts the electrical signal through the interventricular septum to the apex of the heart
What are the left and right bundle branches
400
Inflammation of the pericardium, which is so painful it can cause the heart to stop beating
What is pericarditis
500
The fibrous pericardium anchors the heart into this region of the thorax
What is the mediastinum
500
Papillary muscle anchored to chordae tendinae are responsible for prevention of this
What is eversion of AV valves
500
The fibrous skeleton is composed of this type of tissue
What is dense regular connective tissue proper
500
These structures fan out from the apex and instruct the ventricles to begin their contraction from apex up
What are purkinje fibers
500
Progressive weakening of the heart, leading to overfilled ventricles and causing pulmonary or systemic edema
What is heart failure
