Cardiovascular Assessment and Diagnostics:
Heart Anatomy, Function, and Disease Exam
Questions with 100% Correct Answers |
Verified 2026 | ASSURED SUCCESS
What is the priority concept of Chapter 27? - CORRECT ANSWERS Perfusion
What interrelated concept is discussed alongside perfusion? - CORRECT ANSWERS Fluid and
Electrolyte Balance
What is the size and location of the heart? - CORRECT ANSWERS About the size of a fist,
located in the mediastinum between the lungs.
How much blood does the heart pump with each beat at rest? - CORRECT ANSWERS About 60
mL of blood, or 5 L/min.
What happens to the amount of blood pumped during strenuous physical activity? - CORRECT ANSWERS
It can double to meet increased gas exchange needs.
What protects the heart? - CORRECT ANSWERS A covering called the pericardium.
What separates the right and left halves of the heart? - CORRECT ANSWERS A muscular wall
called the septum.
What type of blood does the right atrium receive? - CORRECT ANSWERS Deoxygenated
venous blood from the body.
, What is the function of the right ventricle? - CORRECT ANSWERS It generates pressure to
close the tricuspid valve, open the pulmonic valve, and propel blood into the pulmonary artery.
What does the left atrium do? - CORRECT ANSWERS Contracts to pump the remaining blood
volume into the left ventricle.
What is the role of the left ventricle? - CORRECT ANSWERS Generates pressure to close the
mitral valve and open the aortic valve, propelling blood into the aorta.
What are the two types of cardiac valves? - CORRECT ANSWERS Atrioventricular (AV) valves
and semilunar valves.
What do the AV valves do? - CORRECT ANSWERS Separate the atria from the ventricles and
prevent backflow of blood during systole.
What prevents blood from flowing back into the ventricles during diastole? - CORRECT ANSWERS
The semilunar valves (pulmonic and aortic valves).
What is the normal range for Mean Arterial Pressure (MAP) to maintain perfusion? - CORRECT
ANSWERS Between 60 and 70 mm Hg.
What does diastole consist of? - CORRECT ANSWERS Relaxation and filling of the atria and
ventricles, comprising about two-thirds of the cardiac cycle.
What occurs during systole? - CORRECT ANSWERS Contraction and emptying of the atria and
ventricles.
What triggers myocardial contraction? - CORRECT ANSWERS The release of calcium ions from
the sarcoplasmic reticulum and blood.
