Sherwood: Chapter 9

Objective:  Changes in venous capacity directly influence the magnitude of  venous return,  which in turn is an important determinant of effective circulating blood volume.

1.  Venous return to the heart
        a.  sympathetic stimulation
        b.  skeletal muscle pump
        c.  one-way valves
        d.  respiratory activity
        e.  ventricular contraction
2.  Blood pressure
        a.  short-term adjustments
        b.  long-term adjustments
        c.  baroreceptor reflex
        d.  cardiovascular control center in the medulla
3.  Hypertension, hypotension and circulatory shock
