Lecture 22:  Cardiovascular System - Solute Exchange

Sherwood: Chapter 9

Objective:  Diffusing molecules have only a short distance to travel between the blood and surrounding cells because of the extensive capillary system.

1.  Diffusion
2.  Bulk flow
        a.  ultrafiltration
        b.  reabsorption
3.  Lymphatic system
4.  Fluid movement across the capillary
        a.  capillary blood pressure
        b.  plasma colloid osmotic pressure
        c.  interstitial fluid hydrostatic pressure
        d.  interstitial fluid colloid osmotic pressure
