Test your knowledge on body fluids and their distribution in the human body

• Total body fluid is 55-60% of body weight in young men and 45-50% in young women.
• Body fluid is distributed between intracellular and extracellular fluid.
• Intracellular fluid is 2/3 of body fluid and 40% of total body weight.
• Extracellular fluid is 1/3 of body fluid and 20% of total body weight.
• Extracellular fluid can be divided into interstitial fluid, blood plasma, and transcellular fluid volume.
• Interstitial fluid surrounds all cells except blood cells and includes lymph.
• Blood plasma is the fluid portion of the blood.
• Transcellular fluid volume represents fluid in structures lined by epithelium.
• Examples of transcellular fluid volume include digestive secretion, sweat, and cerebrospinal fluid.
• Edema is the palpable swelling produced by expansion of interstitial fluid volume.
