2b Connective Tissue Flashcards
What is the most abundant tissue type?
Connective
How does connective tissue relate to epithelial tissue?
It’s less dense
Describe the structure of connective tissue
Composed of cells, fibers, and extracellular components embedded in fluid
How does the structure of connective tissue relate to its functionality?
The structure allows it to provide support while remaining pliable
What is a fibroblast?
Cells that make connective tissues
List some examples of connective tissue
- blood
- bone
- cartilage
- tendons
- ligaments
- adipose (fat)
- lymph
Components of extracellular portion of connective tissue
- interstitial fluid
- adhesion proteins
- proteoglycans
- collagen
- elastin
- reticular fibers
Interstitial fluid
Contains proteins and cells
Adhesion proteins
Allow cells to bind to each other and to structural fibers
Proteoglycans
Proteins that act to filter fluids through the ground substance
Collagen
Extremely strong fibers that provide support
Elastin
Fibers that can stretch and return to og shape
Reticular fibers
Fine networking fibers
Functions of connective tissue
Protects, stores the energy of, supports, transports, insulates, and connects all body tissue
