Which of the following statements accurately describes the pattern of ventricular contraction?
A) The ventricles contract from the base toward the apex moving blood into the great arteries located inferior to the ventricles.
B) The ventricles contract from the apex toward the base moving blood into the great arteries located inferior to the ventricles.
C) The ventricles contract from the apex toward the base moving blood into the great arteries located superior to the ventricles.
D) The ventricles contract from the base toward the apex moving blood into the great arteries located superior to the ventricles.
Ventricular Contraction
The phase of the cardiac cycle in which the ventricles of the heart contract, pumping blood out of the chambers.
Apex
The top or highest part of something, such as the pointed end of the heart that points downward to the left.
Base
A substance that can accept protons or donate a pair of electrons to form a bond, usually raising the pH of a solution when dissolved in water.

Final Answer :
C
Explanation :
The ventricles contract from the apex toward the base, which efficiently pushes blood into the great arteries (aorta and pulmonary artery) located superior to the ventricles. This direction of contraction helps in maximizing the ejection of blood.
