Unformatted text preview: Lab 4 What are the parts of the CVS? ◦ Heart  Dual pumps  4 chambers, one-way valves ◦ Vasculature  Arteries  Arterioles  Capillaries  Venules  Veins ◦ Blood What are the jobs of the CVS? ◦ Deliver oxygen ◦ Deliver nutrients ◦ Remove carbon dioxide ◦ Remove waste products ◦ Transport hormones ◦ Regulates temperature ◦ Buffers changes in pH What changes with exercise? What aspects of the CVS are regulated? ◦ Cardiac output ◦ Heart rate ◦ Stroke volume ◦ Blood pressure  Systolic  Diastolic  Mean ◦ Total peripheral resistance  Vasodilation and vasoconstriction ◦ What can we measure? What must be calculated? Equations are on page 39 Mean arterial pressure ◦ MAP = 1/3 SBP + 2/3 DBP or MAP = CO x TPR Pulse pressure ◦ PP = SBP – DBP Cardiac output ◦ CO = SV x HR Stroke volume ◦ SV = PP x arterial distensibility or SV = CO/HR Total peripheral resistance ◦ TPR = MAP/CO...
