Skeletal system
Bones and joints
Muscular system
Skeletal muscle tissue
Nervous system
Brain, spinal cord, nerves, specific sense organs (eyes, ears)

Catabolism
Breakdown
Anabolism
Building up
Homeostasis
Condition of equilibrium in the body’s internal environment due to the constant interaction of the body’s many regulatory processes
Control of Homeostasis
Receptors –> Control centre –> Effector
What 2 systems regulate homeostasis?
Nervous and Endocrine
Negative feedback loops
Response reverses the change in the controlled condition
Positive feedback loop
the response enhances the original stimulus that changed the controlled condition (labour, blood clotting)
Disorder
Any abnormality of function or structure.
Disease
More specific term for an illness characterized by a recognizable set of signs and symptoms
