- a is medial to the right atrioventricular valve. Small node of specialized cardiac muscle fibers that gives rise to the atrioventricular bundle of the conduction system of the heart.
- b opens into the pulmonary trunk.
- c Allow cytoplasm to flow freely between cells, resulting in areas of low electrical resistance between the cells.
- d carries blood to the lungs and returns it to the left side of the heart.
- e The movement of Ca2+ through the plasma membrane, including the membranes of the T tubules, into cardiac muscle cells stimulates the release of Ca2+ from the sarcoplasmic reticulum.
5 Multiple Choice Questions
- membrane channels open, bringing about the depolarization phase of the action potential.
- is an artery that exits the heart, carries blood from the left ventricle to the body
- represents repolarization of the ventricles and precedes ventricular relaxation.

Pulmonary Semilunar Valve → is located in the Pulmonary Trunk.
Starling law of the heart → is the relationship between preload and stroke volume.
Pericardium/ Pericardial sac → the major vein draining the tissue on the left side of the heart.
Afterload → thin- walled, form the superior and posterior parts of the heart.
Cardiopulmonary resuscitation (CPR) → depends on a reasonable knowledge of the position and shape of the heart. (compressions and helping the patient breathe.)
