Question

Which of the following is NOT a function of electrical conduction of human heart?

• A. To maintain nerve impulse
• B. To ensure coordinated muscle contraction
• C. To maintain effective pumping of blood
• D. None of the above

Answer 1

The correct option is A

To maintain nerve impulse

The main function of the electrical conduction of the human heart is to pump blood to all parts of the body. The electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood. The conduction system consists of specialised heart muscle cells,and is situated within the myocardium. The pacemaking signal generated in the sinoatrial node travels through the right atrium to the atrioventricular node causing both atria to contract.
