Atrophy

Shrinking in cell size

2

Hypertrophy

increasing in cell size

3

Hyperplasia

Increasing in # of cells

4

Metaplasia

Cell that shouldnt be there

5

Dysplasia

Abnormal cell shape and size

6

What is Hypoxia

decrease oxygen to cells

7

Cellular effects of Hypoxia

decrease Oxidative Phosphorylation --> anaerobic resp takes over--> low ATP=high Lactic Acid= low pH

Fail Na&K pump--> increase intracellular Na&Ca&H20--> edema--> Internal enzyme in circulation= lab test

Low Glycogen

8

Cellular Injury Mechanisms: Extremes of Temperature Hot and Cold

Hot:

  1. increase metabolism
  2. inactivating enzymes
  3. cell membrane disruption
  4. coagulation of blood vessels

Cold: Vasoconstriction--> Hypoxia
