The 4 types of tissue
1) Epithelial-covers surfaces
2) Muscle-skeletal, smooth, cardiac
3) Connective-cells, fibres, ground substance, tendons, ligaments, fascia, blood, fat, and bone

Homeostasis
A condition of equilibrium (balance) in the body’s continually changing internal environment
Homeostasis can be disrupted by
Physical insults
Changes in the internal environment
Physiological stress
Disruptions
Body fluids
Dilute, watery solutions containing dissolved chemicals inside or outside the cell
Intracellular fluid
Fluid within cells
Extra cellular fluid
Fluid outside of cells
Interstitial fluid
Extracellular fluid between cells and tissues
5 types of extracellular fluid
1) blood plasma-ECF within blood vessels
2) lymph-ECF within lymphatic vessels
3) cerebrospinal-ECF in brain and spinal cord
4) synovial-ECF in joints
5) aqueous humor and vitreous body-ECF in eyes
What happens if homeostasis is disrupted
Disease occurs
