Heart murmurs Coronary Circulation - Arteries Coronary Circulation - Veins Angina Pectoris & Myocardial Infarction Fact check
100
heart murmurs
The 1st indication of heart valve problems.
100
Left & right coronary
______ arteries travel within the coronary sulcus of the heart to supply blood to the cells of the heart wall - branches of the ascending aorta
100
Great vein, middle vein
The ______ runs alongside the anterior interventricular artery and the ______ runs alongside the posterior interventricular artery
100
Angina Pectoris
Poorly localized pain sensation in the left side of the chest, the left arm & shoulder, sometimes the jaw & back
100
Coronary
______ arteries are considered functional end arteries
200
Valvular insufficiency
When 1 or more of cardiac valves leak bc the valve cusps don't close tightly enough
200
Circumflex artery
Which artery supplies the left atrium & ventricle?
200
True
True or false: because ventricular myocardium is compressed during contraction, most coronary flow occurs during ventricular relaxation
200
Myocardial Infarction
Due to sudden & complete occlusion of a coronary artery. Region of the myocardium is deprived of oxygen & some of the tissue may die (necrosis)
200
marginal, interventricular
The right coronary artery typically branches into the right ______ artery, which supplies the lateral wall of the right ventricle, and the posterior ______ artery, which supplies the posterior surface of both the left and right ventricles.
300
Rheumatic heart disease
Primary cause of valvular stenosis is?
300
Anastomoses
______ allow coronary arteries to shunt a tiny amount of blood from 1 artery to another.
300
Tachycardia
An increased heart rate that shortens diastole
300
A heart attack
Myocardial Infarction is another name for?
300
AV bundle
There is an opening in the fibrous skeleton that allows the AV node to communicate with the next part of the conduction system, the ______.
400
Valvular insufficiency
Inflammation/disease can cause the free ridges of the valve cusps to become scarred & contracted, allowing blood to regurgitate back through the valve. May cause heart enlargement
400
Posterior atrioventricular artery, anterior atrioventricular artery
The ______ supplies the posterior surface of left & right ventricle while the ______ supplies the anterior surface of both ventricles & most of the interventricular septum
400
Hypotension (low blood pressure)
Reduces the ability of blood flow through the ventricular myocardium.
400
Infarction
Death of tissue due to lack of blood supply
400
No
Does mature cardiac cells go through mitosis?
500
Valvular stenosis
Scarring of the valve cusps so that they become rigid or partially fused & cannot completely open
500
Artery becomes blocked, anastomoses are too tiny to shunt enough blood to the part of the heart supplied by the branch. The part of the heart wall supplied by this branch dies due to the lack of blood flow.
What does Coronary disease cause?
500
Middle, small, and great vein
All drain into coronary sinus which dumps into RA
500
False because women develop flu-like symptoms & are often misdiagnosed
True or false: women experience substernal chest pain that radiates into the left arm/left side of neck because of a myocardial infarction
500
Coronary spasm & atherosclerosis
What leads to angina pectoris or the more severe myocardial infarction?
