In capillary beds, there is mass movement of fluids andmolecules into and out of capillary beds. For movement of fluids,simple diffusion is not sufficient and two pressure-basedmechanisms are utilized.

  1. Describe the action of the competing forces driving filtrationof fluids in a capillary bed.
  2. Describe the action of the competing forces drivingreabsorption of fluids in a capillary bed.
  3. Predict how physiological changes in the capillary beds inresponse to an increase in body temperature restoreshomeostasis.

AB The process of movement of the substances in and out across the capillary blood is by the bulkflow hypothesis The movements of fluids from an area of higher pressure in a capillary bed to an area of lower pressure in the tissues is done by the mechanism of filtration The primary force that drives the molecules across the capillary bed is the Capillary hydrostatic pressure The pressure is exerted by the blood in the capillaries against    See Answer
