767919090	Tissue	Group of cells with a common structure and function
767919091	Apithelial Tissue	Covers the outside of the body and lines the organs and cavities within the body. Closely joined.
767919092	Basement Membrane	A dense mat of extracellular matrix
767919093	Simple Epithelium	Single layer of cells
767919094	Stratified Epithelium	Multiple tiers of cells
767919095	Mucous Membrane	Epithelial cells that line the lumen of the digestive and respiratory tracts
767919096	Connective Tissue	Binds and supports other tissues. Tightly packed cells.
767919097	Loose Connective Tissue	Binds epitherlial to underlying tissues and functions as packing material that holds organs in place
767919098	Collagenous	Nonelastic and does not tear easily when pulled lengthwise.
767919099	Elastic Fibers	Long threads made of a protein called elastin. Rubbery.
767919100	Reticular Fibers	Very thin and branched, connect with connective tissue to adjacent tissues.
767919101	Fibroblast	Secrete the protein ingredients of the extracellular fibers
767919102	Macrophages	Amoeboid cell that roams the maze of fibers, engulds bacteria and dead cells
767919103	Adipose Tissue	Specialized connective tissue that stores fat
767919104	Tendons	Muscle to bone
767919105	Fibrous Connective Tissue	Dense parallel bundles with a large number of collagenous fibers
767919106	Ligaments	Bone to bone (joints)
767919107	Cartilage	Has an abundance of collagenous fibers embedded into a rubbery matrix
767919108	Chondrocytes	Cells confined to scattered spaces in the matrix (lacunae) that secretes chondroitin sulfate and collagen
767919109	Bone	Mineralized connective tissues
767919110	Osteoblast	Bone forming cells
767919111	Haverian Systems	Microscopic structure of hard mammalian bone of repeating units

767919113	Neuron	Functional unit of nervous tissue
767919114	Mucle Tissue	is composed of long cells called muscle fibers that are capable of contracting when stimulated
767919115	Skeletal Muscle	Responsible for voluntary movements
767919116	Striated Muscles	Skeletal muscle
