Body Fluids Flashcards
Interstitial fluid and blood plasm are highly similar with the exception of ____
Protein content
What is one reason for the blood plasm containing proteins?
Osmotic pressure helps pull water into the blood vessels
Why does low serum albumin (protein) levels tend to cause edema
Water can leak out of the blood vessels more easily
Extracellular fluid (interstitial) are either ____ or ___ of blood plasma
Filtrates, derivatives
How are ECF’s distinct from ICF’s?
ECF has high Na+ and Cl- and ICF had high K+ and PO4
Water is taken in at the GI tract which quickly equilibrates with:
Blood plasma, interstitial fluid, and intracellular solutions
How do we lose water
From the kidney, lungs, skin (perspiration), and GI tract
What does starlings hypothesis not explain
Rapid H2O and small molecule exchange
In starlings hypothesis, what pressure is greater on the arteriolar end
Hydrostatic pressure
In starlings hypothesis, what pressure is greater at the venous end of the capillary
Osmotic pressure
Starlings hypothesis
There should be leakage of a filtrate of plasma into the ECF at the arteriolar end and transport ion of water at the venous end
H2O absorbs in the GI-
GI tract->blood -> interstitial fluid -> intracellular solution
Synovial fluid is
Extension of interstitial fluid and normally clear to pale yellow
Where is synovial fluid found
In joints
What does synovial fluid contain
Glucose and electrolytes similar to plasma and sometimes fibrinogens if there is an injury
