| Question |
Answer |
| isovolumetric contraction period |
brief interval of rising ventricular tension, during which the heart volume and muscle fiber length remain unchanged ("wringing out" of blood in ventricles) |
| formula for blood pressure |
BLOOD PRESSURE = CARDIAC OUTPUT X TOTAL PERIPHERAL RESISTANCE |
| auscultation method |
a way to measure systolic and diastolic BP |
| mean arterial pressure (MAP) |
average BP values; MAP = DIASTOLIC BP + [.333(SYSTOLIC - DIASTOLIC BP)] |
| precapillary sphincter |
ring of smooth muscle that encircles the vessel at its origin; controls capillary diameter |
| capacitance vessels |
the veins: they serve as blood reservoirs (normally contain 65% of the total blood volume at rest) |
| phlebitis |
condition in which the venous wall becomes inflamed and progressively deteriorates |
| thrombus |
blood clot |
| rate-pressure product (RPP) |
index of relative cardiac work that relates closely to directly measured myocardial oxygen consumption and coronary blood flow in healthy subjects over a wide range of exercise intensities; RPP = Systolic BP X Heart Rate |
