WGU D236 PATHOPHYSIOLOGY FINAL EXAM 2 VERSIONS WITH 100% CORRECT QUESTIONS AND ANSWERS VERSION 1 Explain Starling's Law of Capillary Forces and how it causes edema. - Starling's hypothesis states that the fluid movement due to filtration across the wall of a capillary is dependent on the balance between the hydrostatic pressure gradient and the pressure gradient across the capillary. This causes edema by the retention of water in the tissues instead of vascular system. Why is it...

Phases of Inflammation: Vascular Permeability - Inflammation stimulates blood vessel dilation and opening of capillary pores. Capillary pores allows fluid and cells (WBCs and platelets) to arrive at site of injury. Phases of Inflammation: Cellular Chemotaxis - Chemical signal that calls out to WBC's to site of injury. Results in leukocytosis, where WBCs are released from the bone marrow and into the blood stream. **Doctor is able to analyze the type of WBC and number of WBCs to determine ...
