What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? - ANSWER Starling's Law describes how fluids move across the capillary membrane. There are two major opposing forces that act to balance each other, hydrostatic pressure (pushing water out of the capillaries) and osmotic pressure (including oncontic pressure, which pushes fluid into the capillaries). Both electrolytes and proteins (oncontic pressure) in the blood affe...

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...

A single lymphocyte will have a receptor with a? - Single specificity. One cell may have many receptors (~120,000) but all will recognize the same epitope. Adaptive Immune system - •Takes longer to develop (~7 days) •Is highly specific for antigens, including those associated with microbes •Uses one type od receptor to recognize many different pathogens •Primary immune response = first time the adaptive immune response is activated against a pathogen. •Secondary immune response =...
