Connective Tissue
Function
Binds organs together, providessupport and protection, fills spaces,produces blood cells, and stores fat
i.e. Protection for epitheliumand internal organs
Can form protective covering
Connect muscles to bones, andbones to other bones and joints
Found
In the lungs, arteries, urinary bladder, internalorgans, tendons, ligaments, beneath the skin,around the kidneys, on the surface of theheart, lymph nodes
Are cartilage, bones, and blood
Types
Differ according to thype of matrixand the abundance of fibers in thematrix
Loose Fibrous and Dense Fibrous Tissues
Adipose Tissue and ReticularConnective Tissue

Not all people classify this as aconnective tissue (vascular tissueinstead)
Appearance/ Composition
Are widely seperated by a matrix (made up of anoncellular material that can vary from beingsolid to semifluid to fluid
Connective Tissue
Nervuous Tissue
Function
Recieves stimuli and conducts nerve impulses
Nervous system has three functions:sensory input, integration of data, andmotor outout
Found
In the brain and spinal cord (nervous system)
Appearance/ Composition
Contains neurons: specialized nervous cells

Contain Neuroglia
Nine times more in number than neurons
Support and nourish neutrons
Picture
Epithelial Tissue a.k.a Epithelium
Function
Mainly for protection
External: from injury, dryingout, pathogen invasion
Internal: secrets mucus along digestivetract and sweeps up impurities from thelungs
Also for secretion, absorption,excretion, and filtration
Found
Covers body surfaces and lines boy cavities
In the lining of the lungs, blood vessels,kidney tubules, digestive tracts, andoviducts
Types
Squamous epithelium
Cubodial epithelium
Columnar epithelium
Appearance/ Composition
Occur in more than one layer
Named according to the shape of the cell
Cells lining a body cavity can beciliated and/or grandular
