Tissue
Group of specialized cells that are similar in structure and function
4 basic types
epithelial
connective
muscle
nerve
Epi-

Epithelial tissue
serves as the outer covering for external and internal body surfaces
Main function of epithelial tissue
protect, absorb, secrete
where to find epithelial tissue

connective tissue
most widespread and forms the framework for the body
connective tissue function
holds organs in place and connects body parts together
7 types of connective tissue
bone cartilage dense fibrous reticular tissue loose ordinary adipose hematopoietic
bone
hard and unbendable, supports and protects the body
cartilage
firm but bendable
dense fibrous
strong and bendable, found mostly in tendons and ligaments
reticular tissue
found in weblike networks supports nerves and capillaries provides support for spleen, lymph nodes and bone marrow
