Fluid and Electrolytes Part 1
Posted on YouTube by Campbellteaching. This video discusses the fluid
compartments of the body, the intracellular and extracellular compartments.
Fluid movement is addressed, especially the osmotic movement of water to maintain
blood pressure and interstitial fluid volume. Other videos by Campbellteaching address
additional aspects of fluids and electrolytes.

Molecular Movement (Brownian Motion) using
Milk (or India Ink)
This workbook video (no audio) is a quick review of the laboratory activity
- The Microscopic Observation of Milk (Dilute India Ink is
additionally shown). Both
milk and India ink contain minute particles that are observed to continually
"dance" (Brownian Motion - due to the kinetic energy expressed by the water).

Capillary Pressure
Best of YouTube - Animation from NurseReview.org. This short video
(sound gets better) discusses the changes to capillary pressure and fluid
movement in response to: (1) vasodilation of arterioles, (2) shock, (3)
congestive heart failure, and (4) decreased oncotic pressure.
(1) Vasodilation of arterioles resulting in increased pressure at
arterial end of capillary which promotes fluid movement from plasma into
interstitial fluid (IF). This may result in decreased blood pressure and edema.
(2) In shock decreased vascular pressure results in the response of
arteriole vasoconstriction (to increase blood pressure). Vasoconstriction
results in decreased fluid movement from the capillary (blood pressure to
capillary is decreased) with increased movement from the IF to plasma (helps
increase blood pressure).
(3) Congestive heart failure results in increased venous pressure
(capillary blood pressure increases) which promotes fluid movement from the
plasma to IF resulting in reduced blood pressure and edema.
(4) Decreased oncotic pressure is decreased osmotic pressure of the
plasma due to decreased concentration of "osmotic" proteins such as albumin and
results in decreased fluid return to plasma (plasma does not have adequate
osmotic "pull"). Results in fluid accumulation in IF and edema. If there
was an increase of protein concentration of IF (due to severe burns) the
IF osmotic pressure increases. Increased osmotic pressure of IF counteracts
plasma osmotic pressure resulting in reduced IF fluid return and edema.
