tissues
large body cavity that includes the thoracic, abdominal and pelvic cavities
ventral body cavity
ductless glands that release their products directly into the bloodstream
endocrine glands
2 or more layers of cells
stratified
produces a change to a variable; the factor being regulated
stimulus
covering, lining, and glandular tissue; covers all free body surfaces and lines body cavities; protects, absorbs, filters, secretes

muscle tissue
receives and conducts electrochemical impulses
nervous tissue

organs

control center
another name for nerve cells
neurons
when the body initiates a response that increases the imbalance until a specific goal is reached
positive feedback
dilute saltwater solution surrounding cells where materials are exchanged between cells and blood
interstitial fluid
assumed body position used when referring to body parts and position; standing, face-front, feet parallel, arms at sides with palms facing forward
anatomical position
lengthwise or longitudinal plane through the body
sagittal plane
primary method by which homeostasis is controlled by the body; an imbalance is corrected by a response that restores balance
negative feedback
divides the body into anterior or posterior parts
frontal plane
the tendency of the body to maintain internal stability
homeostasis
