Body Tissues
Tissues are groups of cells with similar structure and function
Four primary types of tissues:
1. Epithelium tissue
2. Connective tissue
3. Nervous tissue
4. Muscle tissue
I. Epithelial Tissues
A. 4 Basic Functions
1.Protection
2.Absorption
3.Filtration
4.Secretion
B. Classification of Epithelium
1. Number of cell layers
• Simple – one layer
• Stratified – more than one layer

2. Shape of cells
1. Squamous – flattened
2. Cuboidal – cube-shaped
3. Columnar – column-like

E. Glandular Epithelium
• Secretes a particular product
• Two major gland types
Exocrine glands have ducts
Location - Sweat and oil glands
Endocrine glands do not have ducts
Location - Pituitary gland
Connective Tissue
A. Functions
1. Binds body tissues together
2. Supports the body
3. Provides protection
Also Note: Connective tissue has varying amounts of vascularization AND typically contain extracellular matrix
B. Connective Tissue Types
1. Osseous (bone)

III. Muscle Tissue
A. Three types
• Skeletal muscle
• Cardiac muscle
• Smooth muscle
