Unit 1- Tissues (Anatomy)
This contains cells, platelets, and plasma
Blood
What are the four major types of tissues?
Epithelial, connective, muscle, nervous
Some epithelial cells contain additional features such as cilia or goblet cells. What are these structures and what is their function?
Goblet cells secrete mucous and the cilia are hair-like structures on the cells which move to help propel the mucous layer
Muscle (function)
Movement
The upper layer of your skin is lined with this type of tissue
Stratified Squamous
Connective (function)
Supports
Why is it better for air sacs in the lungs to be composed of simple squamous tissue than stratified squamous tissue
Air sacs are lined with simple squamous which better allows materials such as oxygen and carbon dioxide to diffuse across the cell easier
Nerves (function)
Control
Epithelial (function)
Covers
Can transport materials like oxygen and wastes
blood

Epithelial cells are nourished by substances diffusing from connective tissue d. Injuries to epithelial tissue heal rapidly as new cells replace damaged ones.
