| The Heart | ||
| #1 | Receiving chambers of the heart. | atria |
| #2 | Blood leaves the left ventricle through what valve? | aortic semilunar valve |
| #3 | The sac-like structure that surrounds the heart. | pericrardium |
| #4 | Oxygen poor is delivered to the heart through which vessels | inferior and superior vena cavae |
| #5 | The valve that prevents backflow of blood into the left atrium. | mitral/bicuspid |
| Vessels | ||
| #1 | The carotid, brachiocephalic and the subclavian arteries all branch off of which vessel? | Aortic arch |
| #2 | The circulation from the right side of the heart, through the lungs and to the left side of the heart is known as... | pulmonary circulation |
| #3 | The structure referred to as the pacemaker of the heart. | sinus node |
| #4 | Vessels that supply blood to the heart muscle. | coronary arteries |
| #5 | Moves blood from the left side of the heart through the tissues and back to the right side of the heart. | systemic circulation |
| Heart Abnormalities | ||
| #1 | Abnormally rapid heart rate (higher than 100 bpm) | tachycardia |
| #2 | Lack of adequate blood supply to the heart that leads to fibrillation. | ischemia |
| #3 | Heart attack. | myocardial infarction |
| #4 | Abnormally low heart rate (Less than 60 bpm) | bradycardia |
| #5 | Inflammation of a vein that results when a clot forms in a vessel with poor circulation. | thrombophlebitis |
| Blood Pressure | ||
| #1 | The amount of blood pumped out by each side of the heart in 1 minute. | cardiac output |
| #2 | Volume of blood pumped out by each ventricle with each heart beat | stroke volume |
| #3 | The force that blood exerts against the inner walls of the vessels | blood pressure |
| #4 | Term associated with the relaxation of the heart. | diastolic/diastole |
| #5 | Term associated with the contraction of the heart muscle. | systolic/sysotole |
| Heart Miscellenous | ||
| #1 | Thyroid hormone that increases heart rate. | thyroxine |
| #2 | Stiffening of the flaps of valves due to repeated bacterial incections | endocarditis |
| #3 | The cords that anchor the valves to thee walls of the ventricles | cordae tendinae |
| #4 | The tissue that makes up the heart muscle. | myocardium |
| #5 | The pointed region of the heart that points toward the left hip and rests on the diaphragm. | apex |
| Final Question | |
| What vitamin must be supplemented in cases of steatorrhea (the inability to absorb fat) to avoid clotting problems? | Vitamin K |
