- how is CO related to SV and heart rate (HR) – give equation
- effects on CO when: HR increases and SV stays the same, SV decreases and HR stays the same,
cardiac diseases/conditions
- Blood pressure (BP):
- how is BP related to CO, peripheral resistance (PR), HR, and SV
- effect of BP on: systemic vasoconstriction, systemic vasodilation, atherosclerosis, bradycardia and
tachycardia, catecholamines, ADH and aldosterone (stress response), renin, sitting up too quickly
after lying down (orthostatic hypotension), smoking, kidney disease, hypervolemia, hypovolemia
- function of each of the following in BP regulation: sympathetic nervous system, parasympathetic
