Cardiology Basic Level
Cardiology is a study in which one gets to understand the diseases and abnormalities that affect the heart. Most of these disorders are life threatening. A cardiologist specializes in diagnosing and treating diseases of the cardiovascular system. Take up this basic level quiz on cardiology and get to learn more about the subject.
- 1.
The Heart is a double-pump which supplies blood throughout the entire body initially via the aorta! T or F
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The heart is considered a double pump due to its dual chambered system of mechanics (ie 2-atria & 2-ventricles). All blood leaving the heart first enters the aorta (largest artery in the body).Rate this question:

What is the special area in the right atrium containing special nerves in which the regulation of systole can be maintained?
- A.
Mans Nerve Bundle
- B.
Neuronal Cardiovascular Bundle
- C.
Atrioventricular Bundle
- D.
Atrioventricular Node
- E.
Sinoatrial Node
Correct Answer
E. Sinoatrial NodeExplanation
The Sinoatrial Node (SA Node) is literally the pacemaker of the heart...it regulates heart rate through specialized conduction and first communicates to the atria causing them to contract and then communicates to the atrioventricular node which in turn communicates to the ventricles causing them to contract. Systole refers to heart contraction.Rate this question:

This protein is an actin-binding protein involved with actin mechanics in heart muscle tissue!
- A.
Tropomyosin
- B.
Beta-Myosin
- C.
Gamma-Myosin
- D.
Alpha-Myosin
- E.
Delta-Myosin
Correct Answer
A. TropomyosinExplanation
Tropomyosin and also troponin are special proteins responsible for the regulation of the mechanics involved with actinRate this question:

When approximately does the human heart start beating after conception?
- A.
10 days
- B.
16 days
- C.
21 days
- D.
30 days
- E.
52 days
Correct Answer
C. 21 daysExplanation
Most scientific evidence says usually around 21 days. Isn't that amazing?Rate this question:

- 5.
Which myocardial fibers located in the inner-ventricular walls of the heart receive the electrical impulse from the atrioventricular node?
- A.
Ventricular myocardial fibers
- B.
Atrioventricular branch
- C.
Septum branch
- D.
Myocardial branch
- E.
Purkinje fibers
Correct Answer
E. Purkinje fibersExplanation
A weird name yes but only due to the fact its discoverers last name was purkinje (discovered 1839). These fibers are highly specialized and very efficient in regards to neuronal impulse activityRate this question:

- 6.
Anastomoses refers to what in cardiology?
- A.
Blood flows almost slow in a particular coronary artery
- B.
Blood flows fast in a particular coronary artery
- C.
A network of coronary arteries which are inefficient
- D.
A network of coronary arteries which supply an efficient arterial junction
- E.
A network of two arteries joining to supply blood to myocardium
Correct Answer
E. A network of two arteries joining to supply blood to myocardiumExplanation
Can be seen on specific x-ray scans of heart and or MRI. Not uncommon to see this.Rate this question:

- 7.
After birth which anatomical hole closes as to allow proper functioning of the lungs?
- A.
Foramen ovale
- B.
Oblique ovale
- C.
Circumflex ovale
- D.
Mitral ovale
- E.
Atrial ovale
Correct Answer
A. Foramen ovaleExplanation
The foramen ovale is an important structure in the fetal heart allowing blood to flow directly into the left atrium from the right atrium. Blood is directly bypassed due to the fact the lungs of the fetus do not breathe while in the womb and the blood is oxygenated by the maternal lungs. Therefore it is not necessary for the blood of the fetus to divert to its own lungs via the right atrium...instead it goes directly to the left atrium.Rate this question:
-
- 8.
The artery that supplies the posterior interventricular artery (ie. PDA) determines coronary dominance. If the circumflex artery (ie. CX) then the coronary dominance is known as?
- A.
Right
- B.
Left
- C.
Anterior
- D.
Superior
- E.
Inferior
Correct Answer
B. LeftExplanation
Conversely if the right coronary artery supplied the PDA then the heart would have right coronary dominance. It is a myth that everyones heart is anatomically the same. Some people have more coronary arteries & veins than others...some have less. We are all different. Even some people have more lobes in their lungs than others. The human body is a marvel!Rate this question:
-
- 9.
Describe the pathway of blood throughout the heart (not including coronary circulation) from the venous system to the arterial system (ie. ending at aorta and starting ar inferior and superior vena cava). NOTE: Not looking for a medical school answer...just trace the pathway using common anatomical structures.
