Physiology Lecture Review: Body Fluids and Homeostasis

Vocabulary flashcards covering key concepts from the physiology lecture on body fluid compartments, homeostasis, and SOAP notes.

Extracellular Water Fraction

Approximately one-third of total-body water.

Extracellular Fluid Proportion of Body Weight

Approximately 20% of a person's body weight.

Plasma

A component of extracellular fluid that exchanges oxygen, nutrients, wastes, and other substances with interstitial fluid.

Intracellular Fluid Proteins

Proteins important in regulating cellular events such as growth and metabolism, which must be retained within intracellular fluid.

Extracellular Fluid Components

Interstitial fluid and plasma, which are separated from each other by blood vessel walls.

Blood Loss Immediate Impact

The plasma compartment would be immediately affected by significant loss of blood.

Restoring Plasma Volume

A simple way to help restore the volume of plasma is with an intravenous infusion of blood or a fluid similar in composition to plasma.

Homeostasis

A constant internal environment that is a prerequisite for good health.

Interstitial Fluid

The fluid in contact with most cells, found with water and solutes like ions and gases, moving back and forth between cell interiors and nearby capillaries.

Blood Glucose Regulation

A homeostatic mechanism where compensatory processes restore increased blood glucose levels (after a meal) toward their pre-meal concentration.

Endocrine System

The system responsible for regulating the uptake of glucose from the blood into organs such as muscles.

Dynamic Constancy

A characteristic of physiological variables, meaning they can fluctuate within a certain range over any short interval, but their average over a long period of time is stable and predictable.

Homeostatic Interrelation

When one physiological variable is out of balance, other variables in the body may also become non-homeostatic, potentially leading to severe conditions.

SOAP Notes

A structured method of documentation in healthcare, standing for Subjective, Objective, Assessment, and Plan.

Subjective (SOAP)

Information the patient tells, such as symptoms and complaints.

Objective (SOAP)

Information the clinician observes during examination or testing.

Assessment (SOAP)

The diagnosis or identified problem based on subjective and objective information.

Plan (SOAP)

The treatment or protocol strategy for the patient.

Importance of Accurate SOAP Notes

Ensures that the patient undergoes the correct treatment plan according to their diagnosis.
