Question | Answer |
Cardiac Cycle | Events of one complete heartbeat |
Pressure Points | Point where you can feel the blood flowing through the veins, feeling the heartbeat |
Hypertension | An abnormally high blood pressure |
Arteriosclerosis | Any of a number of proliferative and degenerative changes in the arteries leading to their decreased elasticity |
Apex | Point of the heart |
Arterial Blood | Oxygenated blood held/carried by the arteries |
Arteries | Vessels that carry blood AWAY from the heart |
Arterioles | Minute arteries |
Blood Pressure | Pressure exerted on the inner walls of a blood vessel |
Capillaries | Minute blood vessels connecting arterioles with venules |
Diastole | A period, between contractions, of relaxation of the heart during which it fills with blood |
Fibrillation | Irregular, uncordinated contraction of muscle cells, particularly of the heart musculature |
Myocardium | the cardiac muscle layer of the heart wall |
Pericardium | The membranous sac enveloping the heart |
Septum | Divides and separates the heart into left and right halves |
Serous Fluid | A clear, watery fluid secreted by the cells of a serous membrane, found between membranes of the heart, this reduces friction |
Systole | The contraction phase of heart activity |
Vein | A vessel CARRYING blood away from the tissues towards the heart |
Venules | Small veins |
Cause of Hypertension | Fever, physical exertion, and emotional upset |
Good Blood Pressure Level | 120 over 80 |
Deoxygenated Blood Path (Right Side) | In superior vena cava, in right ventricle, out pulmonary artery and sent to the rest of the body |
Oxygenated Blood Path (Left Side) | In pulmonary veins, in left ventricle, out aorta and into the lungs |
