Connective Tissue
General Features
- Most abundant tissue in your body
- Binds structures together
- Provides support, protection, fills space, stores fat, produces blood cells, fights infection
- Composed of many scattered cells within an extracellular matrix
- Made up of ground substance (fluid, semi-solid) and fibers
- Most has a good blood supply
Types of Cells in Connective Tissue- Mast Cells: prevents blood clots
- Macrophages: consumers; engulf bacteria
- Plasma Cells: secrete antibodies
- Adipocytes (fat cells): store triglycerides
- Fibroblasts: produce fibers and ground substance- Collagen- Elastic- Reticular

Types of Fibers in Connective Tissue- Collagen Fibers (colla = glue): strong and flexible
- Bones, ligaments, tendons
- Elastic Fibers: very flexible- Skin, blood vessels, lung tissue
- Reticular Fibers: (reticul- = net): provide supporting framework- Many soft organs

Categories of Connective Tissue
- Loose Connective Tissue
- Dense Connective Tissue
- Cartilage
- Bone Tissue
- Liquid Connective Tissue
Loose Connective Tissue
- Binds underlying organs to skin and to each other
- Forms delicate thin membranes throughout the body
Dense Connective Tissue
Cartilage
Chondrocytes: provide support, attachment, cushion
Bone and Liquid Tissue
Osseous Tissue: supports soft tissue, protects delicate structures, help
generate movement
Liquid Tissue: Blood and Lymph
Connective Tissue Disorders and Diseases
Ehlers-Danlos Syndrome
Osteogenesis imperfecta
Rheumatoid arthritis
