Answer:
The options
A) "Efficient heart function requires that the ventricles do not retain any blood at the end of the cardiac cycle."
B) "Recall that the heart sounds that we listen to as part of our assessments are the sounds of the myocardium contracting."
C) "The diastolic phase is characterized by relaxation of ventricles and their filling with blood."
D) "Aortic pressure will exceed ventricular pressure during systole."
The CORRECT ANSWER IS C)
C) "The diastolic phase is characterized by relaxation of ventricles and their filling with blood."
Explanation:
Diastole is connected with ventricular filling and relaxation. Cardiac production is not 100% or in proximity to been 100% with every cardiac cycle, as the heart sounds are linked with valve closure. Ventricular pressure surpasses that of the aorta in the course of the systole.

Answer:
A protein needed for blood clot formation.
Explanation:
Prothrombin may be defined as the protein that changes in to the thrombin during the process of blood coagulation with the help of clotting factor X.
The main function of the prothrombin protein is the coagulation of blood. This protein is responsible for blood clotting at the time of external and internal injury.
Thus, the correct answer is option (c).
