Bio 669 Ch 5 Fluid Balance Questions AND ANSWERS
WITH 100% CORRECT ANSWERS LATEST UPDATE
2024/2025.
4 causes of edema - ANSWER 1. increased capillary hydrostatic pressure
2. decreased plasma oncotic pressure
3. lymphatic channel obstruction
4. increased capillary membrane permeability
Total body water (TBW) is what percent of body weight in adults - ANSWER 60%
Intracellular fluid makes up how much TBW - ANSWER 2/3
extracellular fluid makes up how much TBW - ANSWER 1/3
capillary hydrostatic pressure (blood pressure) - ANSWER facilitates the movement of water
from the capillary into the interstitial space
capillary (plasma) oncotic pressure - ANSWER osmotically attracts water from the interstitial
space into the capillary
interstitial hydrostatic pressure - ANSWER facilitates the inward movement of water from the
interstitial space into the capillary
interstitial oncotic pressure - ANSWER osmotically attracts water from the capillary into the
interstitial space
aquaporins - ANSWER class of water channel proteins that are permeable to water
main extracellular cation - ANSWER Sodium (Na+)
main intracellular cation - ANSWER Potassium (K+)
Aldosterone - ANSWER Occurs when Na+ levels are decreased and K+ levels are increased.
"salt-retaining hormone" which promotes the retention of Na+ by the kidneys. Na+ retention
promotes water retention, which promotes a higher blood volume and pressure. Also promotes the
excretion of K+
Chloride transport is passive and follows the transport of ______ - ANSWER Na+
water balance is regulated by ______ - ANSWER antidiuretic hormone (ADH)
