Module 2 · Homeostasis
Study notes, diagrams, and spaced-repetition flashcards.
Topic 1
Homeostasis
An introduction to homeostasis — the body's drive to keep internal conditions stable within a narrow range around a set point.
Topic 2
Homeostasis and Feedback Loops
How feedback loops — sets of receptors, control centers, and effectors — regulate the body's variables to maintain homeostasis.
Topic 3
Homeostasis Terminology
The key vocabulary of homeostasis — variables, receptors, control centers, set points, effectors, and communication pathways.
Topic 4
Feedback Loops
How negative and positive feedback loops work, with examples of each, to keep the body's variables within a normal range.
Topic 5
Homeostatic Maintenance
How the body maintains homeostasis across calcium, glucose, and cell-number regulation, and what happens when these systems fail.
Topic 6
Diabetes: Type 1 and Type 2
How blood-glucose negative feedback works and how it breaks down in Type 1 (no insulin) versus Type 2 (insulin resistance) diabetes.
Topic 7
Integration of Systems
How multiple organ systems work together — not in isolation — to maintain homeostasis for water, temperature, glucose, calcium, and cell populations.
