Identify whether the given statement is true or false
-Left ventricle->Left atrium->Right ventricle->Right atrium is the correct sequence for blood entering the heart through the vena cavae and leaving through the aorta.
-The sinoatrial node is situated in the wall of the interventricular septum.
-Impulses through the conduction system of the heart follow the ordered path: SA node->conduction myofibers->AV bundle->AV node.
-The heart is covered by the suprardium.
-The “lub” sound of the heart is caused by closing of the semilunar valves.
-To clearly hear the heart sound of the bicuspid valve, a stethoscope should be placed to the left of the sternum at the second intercostal space.
-The left ventricular wall of the heart is thicker than the right wall in order to pump blood with a greater pressure.
-When the atrioventricular bundle is completely interrupted the ventricles typically contract at 30 to 40 beats/min.
-At late diastole, the atria and ventricles are relaxed…
