Questions, Parts 1) and 2): 1) What is the net change in MAP after blood loss? What is responsible for reducing the magnitude of the initial fall in MAP 2) Why is the change in venous return (box 2G) so important in raising MAP? 3) What is the neural pathway that produces the change in epinephrine levels

Unformatted text preview: indicated in box 2D? 4) What is the mechanism behind changes in boxes 2G and 2H? 3A (From 2C) 3B 3D 3E 3F 3G Blood volume P c Sympathetic output to blood vessels Arteriolar vascular resistance Net filtration pressure 3) Fluid shifts Questions: 1) Consider the change indicated in box 3G. If the subject does not bleed anymore or consume fluid, where does the change in blood volume come from? 2) Will the change shown in 3G improve the problem of hypotension? How? 3) What will be the effect of the above fluid shift on hematocrit (% of blood consisting of cells)? 3C Blood volume...
