Anatomical Position

A standardized reference position for the body, where the body is standing erect with arms at the sides, palms facing forward, and feet together.

Homeostasis

The maintenance of a stable internal environment within a body despite external changes.

Negative Feedback Loop

A regulatory mechanism that counteracts changes in the internal environment, bringing it back to the set point.

pH Scale

A measure of the acidity or alkalinity of a solution, ranging from 0-14, with 7 being neutral.
