2. Tissue An aggregation of cells and cell products of similar structure and embryonic origin that perform a common function

3. Histology The study of tissues, especially their structure and arrangement

4. Basic Tissue Types Epithelial Epithelial Connective Connective Muscle Muscle Nervous Nervous

6. Organ An aggregation of tissues organized into a functional unit

7. System Organs working together as functional units

8. Epithelial Tissue Sheet-like layer of cells Sheet-like layer of cells Cover surfaces or line cavities Cover surfaces or line cavities Often has glandular cells for fluid secretion Often has glandular cells for fluid secretion Endothelium Endothelium Epithelium that lines heart, blood vessels and lymphatic vessels Epithelium that lines heart, blood vessels and lymphatic vessels

9. Epithelial Types Simple Epithelium Simple Epithelium Simple squamous – inside blood vessels Simple squamous – inside blood vessels Simple cuboidal – lines ducts, ex. Kidney tubules, mucous glands Simple cuboidal – lines ducts, ex.
