CVP exam II

Drains lymph from right side of head, neck, arm & part of right chest

Drains lymph from lower body & left side of head, upper chest & left arm

change in velocity/ change in Pressure X initial volume
- ability for vessels to stretch

Flow = amnt substance/min divided by artery - vein
- blood flow to a tissue/organ is based on input/output concentration & addition/removal of substances

C.O. = mg dye injected X 60/[avg. dye] X duration of curves in each ml

flow = vol/time

momentary limb blood flow

the ability for a vessel to stretch & hold volume
V>A
- = change vol/ change in pressure or distensibility X initial vol

inversely proportional to compliance & distensibility

arterioles, metarterioles, precapilary sphincters
- vasodil/constrict of precapillary resists vessels

change in tissue vascularity
- angiogenin, vascular endothelial growth factor (VEGF)

as tissue uses up O2, vascular smooth m. cannot maintain constriction

Small peptides stim. growth of new vessels
- e.g. angiogenic factor

up-regulated by stress activated endothelium
- attract monocytes that invade arterioles
