Verified Answers Graded A+
Which cardiac chamber has the thickest wall? - Answer: Left Ventricle
Which statement accurately describes blood flow through the heart?
a. Blood flows from the right atrium through the aortic valve to the right ventricle.
b. Blood flows from the right ventricle through the pulmonic semilunar valve.
c. Blood flows from the right atrium through the tricuspid valve to the right ventricle. Blood
then travels from the right ventricle through the pulmonic semilunar valve to the pulmonary
circulation. Once in the pulmonary circulation, it is oxygenated and travels to the left atrium
through the bicuspid valve to the left ventricle. Blood leaves the left ventricle through the aortic
valve and enters the systemic circulation.
d. Blood flows from the left ventricle through the bicuspid valve. - Answer: Blood flows from the
right atrium through the tricuspid valve to the right ventricle. Blood then travels from the right
ventricle through the pulmonic semilunar valve to the pulmonary circulation. Once in the
pulmonary circulation, it is oxygenated and travels to the left atrium through the bicuspid valve
to the left ventricle. Blood leaves the left ventricle through the aortic valve and enters the
systemic circulation
The A wave is generated by ? - Answer: right atrial contraction
, Which artery travels in the coronary sulcus between the left atrium and the left ventricle? -
Answer: Circumflex
Which part of the heart is responsible for electrical impulse stimulation? - Answer: Sinus Node
Which cardiac event represents the measure of time from the onset of atrial activation to the
onset of ventricular activation? - Answer: The PR interval measures the time of onset of atrial
activation to the onset of ventricular activation.
Which cardiac event represents the QRS complex? - Answer: represents the sum of all
ventricular muscle cell depolarization.
What does the ST interval represent? - Answer: time when the entire ventricular myocardium is
depolarized.
What does the QT interval represent - Answer: The QT interval is often called electrical
ventricular systole.
Frank-Starling law of the heart - Answer: Resting sarcomere length to tension generation. The
volume of blood in the heart at the end of diastole is directly related to the force of contraction
of the next systole.
What is preload? - Answer: it is the pressure generated in the left ventricle at the end of diastole
(end-diastolic volume).
What is afterload? - Answer: it is the resistance or impedance to the ejection of blood from the
left ventricle.
