TRUE or FALSE . WRITE THE WHOLE WORD OF YOUR CHOICE.

The valve that is located on the same side of the heart as the pulmonary semilunar valve is the mitral valve.
Stenosis of the bicuspid valve might cause blood to back up into the venae cavae.
The outermost of the three layers of the heart is the supracardium.
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 pathSA node->conduction myofibers->AV bundle->AV node.
The heart is covered by the suprardium
The “lub” sound of the heart is caused by the 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 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 and the aortic semilunar valve is open
During ventricular contraction, all the blood is forced out of the ventricles.
Cutting the vagus nerves where they innervate the heart would increase the heart rate.
Angina pectoris is the comprehensive term for heart attack.
