Epithelial Tissue

• Covers internal and external structures
• Purpose
• Protection
• Secretion
• Gas exchange
• Basement membrane and connective tissue support
  epithelial tissue

10
Epithelial Tissue - Simple
11
Epithelial Tissue - Stratified
12
Connective Tissue

• Very diverse functions
• Support ? Cartilage, bone, dense, loose
• Energy storage ? Adipose
• Gas exchange ? Red blood cells
• Immune system ? White blood cells

Muscle Tissue

• Smooth
• Controls diameter of tubes (blood vessels and
  digestive system)
• Involuntary
• Striated
• Skeletal attaches to bone
• Cardiac heart muscle

18
Striated Muscle Tissue

• Contain contractile unit composed of actin and
  myosin protein
• Cells bundled together to form muscle fibers
• Densely packed actin/myosin fibers gives striated
  appearance
• Multinucleated cells syncytial

Nerve Tissue

• Neurons functional unit of the nervous system
• Glial Cells support cells
