D)AV node
E)sinoatrial node

Question

Quizplus · Accepted Answer

The myocardium is the muscular tissue of the heart and is responsible for contraction, which generates blood pressure.

Answer: D
 The AV node is a cluster of cells in the heart that receives electrical impulses from the sinoatrial node and delays them slightly before sending them to the ventricles. It does not directly generate blood pressure.

Answer: E
 The sinoatrial node is a group of cells in the right atrium of the heart that acts as the natural pacemaker, initiating the electrical impulses that regulate the heartbeat. It does not directly generate blood pressure.

Answer: A and C
 The tricuspid valve and aortic semilunar valve are both important valves in the heart that regulate blood flow and prevent backflow. However, they do not directly generate blood pressure.
