QUESTIONS AND ANSWERS RATED A+
✔✔pulmonary vein - ✔✔the only vein carrying oxygenated blood, enters the left atrium
✔✔right atrium - ✔✔the chamber where the superior & inferior vena cavae empty blood
✔✔coronary artery - ✔✔artery that nourishes the heart muscle and takes the
myocardium oxygen & nutrients
✔✔auricle - ✔✔"little ear" protrudes from each atrium
✔✔septum - ✔✔myocardial wall that separates ventricles
✔✔apex of the heart - ✔✔tip of the heart pointing down; created by the left ventricle
✔✔cardiac cycle - ✔✔A complete heartbeat consisting of contraction and relaxation of
both atria and both ventricles
✔✔medulla oblongata - ✔✔Part of the brainstem that controls vital life-sustaining
functions such as heartbeat, breathing, blood pressure, and digestion.
✔✔Electrocardiogram (ECG or EKG) - ✔✔A recording of the electrical activity of the
heart

volume and they play an essential role in helping to protect against disease and
infection; innate capacity to recognize and differentiate any foreign material & cells.
✔✔Basophils - ✔✔A circulating leukocyte that produces histamine for inflammatory
responses and trigger allergic reactions in your body.
