Homework Answers
1. Option A is correct as the S1 (lub) the first heart sound is caused by the contaction of ventricles and subsequent closing of tricuspid and bicuspid valve (mitral valve)
2. Option C is correct during atrial systole tricuspid and bicuspid valves are open causing the pumping of the blood in the ventricles
Add Answer to:
The first heart sound, S, ("lub"), is caused largely by the contraction of the ventricles and...

Which of the following are true regarding the heart? Mark (A) for Correct or (B) Incorrect. If incorrect please indicate why! ____ The pulmonic valve opens during systole. ____ The tricuspid valve is a semi-lunar valve anchored to the heart by the myocardium. ____ The aortic valve is open throughout all of ventricular systole Atrial pressure increases during ventricular systole. ____ Ventricular pressure increases during both atrial and ventricular contractions. ____ P waves are associated with preloading the ventricles.

1. In the left ventricle, why does isovolumetric (isometric) contraction occur during the first phase of ventricular systole? A. The bicuspid valve needs time to sit before the ventricle can eject blood. B. Ventricular pressure is greater than atrial pressure so the ventricle cannot eject blood. C. The ventricle is still filling with blood and therefore cannot eject blood during this time. D. Aortic pressure is higher than ventricular pressure and the ventricle must pressurize the blood to open the...

1) Check all that are components of the sympathetic innervation of the heart. Check All That Apply Cervical sympathetic ganglion Spinal cord Spinal cord Vagus nerve (CN X) Cardiac nerve Sympathetic postganglionic axon 2) Check all that occur during ventricular contraction. Check All That Apply The AV valves open to allow blood to enter the ventricles from the atria. The semilunar valves remain closed to prevent backflow of blood into the ventricles. The semilunar valves open to allow blood to...
