Basic tissue types and their primary function

1. Epithelial tissue

   • forms boundaries between different environments, protects, secretes, absorbs, filters

2. Connective tissue

   • supports, protects, binds other tissues together

3. Nervous tissue

   • internal communication

4. Muscle tissue

   • contracts to cause movement

Definition of tissue

A group of cells working together to perform a specific function

How to name epithelial tissue

Based on number of cell layers followed by the shape of the cells

Simple Squamous Epithelium: Function

Diffusion and filtration
