Homeostatic control systems
Feedback control system:
Will do the exact opposite
Negative feedback
Feedback control system:
Amplifies the problem until it ends
Positive feedback
- Intracellular regulation
- Intrinsic regulation
- Extrinsic regulation
Levels of homeostatic control
Specific value range, ex. Temperature
Set point value
Forms covering on all internal and external surfaces
Epithelial tissue
- protection
- secretion
- absorption
- sensory functions
- excretion

Epithelial cells:
Flat and sheet like in appearance
Squamous
Epithelial cells:
Cube like, equal width, height, depth
Cuboidal
Epithelial cells:
Column like, taller than they are wide
