-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.

- Identify whether the following statement is either 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. 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.

- Diastole and systole are terms that address the contracting and relaxing of the heart. Which of the following statements about diastolic and systolic blood pressure are true? Select all that apply. The diastolic blood pressure reading is the second number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure in the arteries when the heart rests between beats. Systole refers to when the heart contracts and blood flows from atria into ventricles.

Beta-blockers slow heart rate by reducing the conduction of action potentials through the A-V (atrioventricular) node.
