Question

When the ventricular myocardium receives an electrical impulse, it stimulates a
contraction that:
only pulls in deoxygenated blood from the body.
O pushes both types of blood to both the lungs and body.
only pushes deoxygenated blood to the lungs.
only pulls in oxygenated blood from the lungs.

Answer 1

C is the correct answer.

The ventricle’s job is to push blood, so in the right ventricle, the ventricle pushes deoxygenated blood to the lungs.

Answer 2

Answer:

pushes both types of blood to both the lungs and body.

Explanation:

These fibers transmit the electrical impulse to the myocardium (cardiac muscle). The myofibers in the ventricular myocardium contract at the same time because the impulses are transmitted rapidly. When the ventricles contract, the blood from both ventricles is forced out through the pulmonic and aortic valves into the pulmonary and systemic circulation.
