TISSUES & FUNCTIONS

Tissues and their functions and locations within the human body

Tissues	Structure/Function/Location
Simple Squamous Epithelium	Structure: Thin, flat, 1 layer. Function: Diffusion, Osmosis, Filtration. Location: Lung air sacs, lining blood/lymph vessels
Simple Cuboidal Epithelium	Structure: cubish, 1 layer. Function: secretion & absorption. Location: Kidney tubules, glands, ovaries
Simple Columnar Epithelium	Structure: Column, 1 layer. Function: secretion, absorption & protection. Location: gastrointestinal tract, respiratory tract
Pseudostratified Ciliated Columnar Epithelium	Structure: column, usually has goblet cells & cilia. Function: secretion, absorption & protection. Location: upper respiratory tract
Stratified Squamous Epithelium Non-keratinized	Structure: flat-square, many layers. Function: protection. Location: esophagus, vagina, oral cavity, anal cavity
Stratified Squamous Epithelium Keratinized	Structure: Flat-square, many layers. Function: protection. Location: skin
Stratified Cuboidal Epithelium	Structure: cubish, usually 2-3 layers. Function: secretion & absorption. Location: larger ducts of glands, ovarian follicle
Areolar (loose) Connective	Structure: has all cell & fiber types. Function: bind organs. Location: beneath skin, between muscles
Adipose	Structure: cells(adipocytes). Function: insulation, protection, energy storage. Location: beneath, around heart & kidneys
Reticular Connective	Structure: varied cells, reticular fibers. Function: bind & support. Location: spleen & liver
Elastic Connective	Structure: elastic fibers & fibroblasts. Function: allow organs & structures to stretch. Location: arteries & lungs
Dense Regular Connective	Structure: Parallel collagen fibers. Function: strong attachment. Location: tendons & ligaments
Dense Irregular Connective	Structure: chaotic collagen fibers. Function: VERY strong attachment. Location: skin & heart valves
Blood	Structure: red & white blood cells, platelets, plasma. Function: transport, immunity, clotting. Location: blood vessels
Cartilage-Hyaline	Structure: chondrocytes & fine collagen fibers. Function: support & flexibility. Location: nose & trachea, ends of bones
Cartilage-Elastic	Structure: Chondrocytes & elastic fibers. Function: support. Location: ear, epiglottis
Cartilage-Fibrous	Structure: Chondrocytes, thick, wavy collagen fibers. Function: support, strong fusion. Location: intervertebral discs, knee, pubic symphysis.
Compact Bone	Structure: osteons. Function: support & protection. Location: everywhere.
Skeletal Muscle	Structure: Striated, multi-nucleated. Function: voluntary movement, heart production. Location: attached to bones
Smooth Muscle	Structure: Nonstriated, 1 nucleus. Function: involuntary movement. Location: organs and blood vessels
Cardiac Muscle	Structure: Striated branched & 1 nucleus. Function: involuntary- pump blood. Location: heart only.
Nervous	Structure: has neurons & neuroglia. Function: neurons send impulses, neuroglia support neurons. Location: brain, nerves, spinal cord
Goblet Cells	Location: intestinal walls
Tight Intercellular Junction	Cell membranes fuse together to prevent leakage. Location: epithelial cells in GI tract, skin
Desmosome Intercellular Junction	Spot welds reinforcement. Location: Epithelial skin cells.
Gap Intercellular Junction	Membranes connected by protein channels. Location: heart muscle, some nerve cells.
Organ	Two or more tissues performing a specific function together.
Exocrine Glands	Secretion is to the outside. Location: sweat glands, salivary glands
Endocrine Glands	Secretion is internal (blood or fluid). Location: thyroid gland & adrenal gland
Endocrine Glands	Glands that are ductless.
Unicellular Exocrine Glands	Glands have ducts. Composed of 1 cell. Example: goblet cell
Mulitcellular Exocrine Gland	Glands have ducts. Composed of many cells. Examples: sweat glands, salivary glands.
Merocrine Glands	Secrete fluid product only. Examples: salivary glands, pancreas & sweat glands
Apocrine Glands	Secrete portions of cells & fluid product. Examples: mammary glands, ceruminous glands
Holocrine Glands	Secrete whole cell & fluid product. Example: sebaceous glands
