25
Atrophy
Reduction in size or number
26
Necrosis
Pathological death of tissue
27
Infarction
cut off blood supply
28
Gangrene
insufficient blood supply
29

Programmed cell death
30
Hyperplasia
Cell multiplication
ie: calus
31
Hypertrophy
Enlargement of cells
ie: weightlifting
32
Neoplasia
Tumor development
33
Differentiation
- Specialization of form or function
34
Metaplasia
- Change from one tissue to another
35
Connective tissue function
- Bind organs
- Support
- Physical protection
- Immune protection
- Movement
- Storage
- Heat production
- Transport
36
collagen fiber
- Tough and flexible
- White fibers of tendons and ligaments
- connective tissure
37
Reticular
- Thin collagen fiber
- Framework of spleen and lymph nodes
38
Elastic
- Stretch and recoil
- Abundent in lungs
39
Loose connective tissue
Areolar
Adipose
Reticular
40
Areolar
- Abundant
- Binds epithelia to deeper tissue
- Ie: skin(papillary layer of dermis), external openings
41
Adipose
- Stores energy
- Protection
- Ie:
- Packed around internal organs
42
Reticular

Regular
Irregular
44
Regular
- Highly organized fibers
- Mainly fibroblasts
