List the four types of tissue found in the human body and give an example of each.
1. Epithelial
2. Connective
3. Muscular
4. Nervous
Epithelial tissue
What are the characteristics of epithelial tissue? it never has contact with another cell, it always has a free surface. They contain no blood vessels (avascular) and depend on underlying tissues for needed nutrients and oxygen sources to maintain homeostasis. it is usually very thin for this reason. The cells are tightly packed together. composed almost entirely of cells. apical and basal surfaces
What is the function of epithelial tissue? protection, secretion, and absorbtion
Where is epithelial tissue found? Epithelial tissue is located on the very outside of an organ.
This is a cross section of the esophagus. Number 1 represents the lumen of the esophagus. Identify the tissue types indicated by 2 and 3.
2. stratified squamous epithelium
3. laminia propria
