Document Summary
Interstitial and intravascular: describe how fluid distribution changes with age. Infants are particularly susceptible to significant changes in tbw because of a high metabolic rate and greater body surface area, as compared to adults. At adolescence the percentage of tbw approaches adult levels and differences according to gender appear. Males have a greater percentage of body water because of increased muscle mass, and females have more body fat because of the influence of estrogen and thus less water. Capillary hydrostatic and interstitial oncotic favors filtration while capillary oncotic and. Interstitial hydrostatic opposes filtration: describe the causation, pathophysiologic process, and clinical manifestations of edema. Edema is a problem of fluid distribution that results in accumulation of fluid within the interstitial spaces. The pathophysiologic process that leads to edema is related to an increase in forces favoring fluid filtration from the capillaries or lymphatic channels into the tissues.
