Question | Answer |
simple squamous epithelium | Location: lining of heart
Function: Allows passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae |
simple cuboidal epithelium | Location: Kidney tubules
Function: Secretion and absorption |
simple columnar epithelium | Location: gallbladder
Function: absorption; secretion of mucus enzymes, and other substances; ciliated type propels mucus(or reproductive cells) by ciliary action |
pseuodostratified columnar epithelium | Location: ciliated variety lines the trachea
Function: secretion, particularly of mucus; proplusion of mucus by ciliary action |
Connective tissue proper:Loose connective tissue, adipose | Location: under skin
Function: provides reserve fuel; insulates against heat loss; supports and protects organs |
connective tissue proper:Loose connective tissue, areolar | Location: surrounds capillaries
Function: wraps and cushions organs;its macrophages phagocutize bacteria;plays important role in inflammation; holds and conveys tissue fluid |
connective tissue proper: loose connective tissue, reticular | Location: spleen
function: fibers form a soft internal skeleton(stroma) that supports other cell types, including white blood cells, mast cells, and macrophages |
connective tissue proper:Dense connective tissue, dense regular(cells compact) | Location: tendons
function: attaches muscles to bones or to muscles;attaches bone to bones;withstands great tensile stress when pulling force is applied in one direction |
connective tissue proper:Dense connective tissue,dense irregular | Location: Dermis of the skin
Function: able to withstand tension exerted in many directions; provides structural strength |
Blood | Location: contained within blood vessels
function: transport of repiratory gases, nutrients, wastes, and other substances |
Giant multipolar neuron | location: brain
Function: transmit electrical signals from sensory receptors and to effectors(muscles and glands)which control their activity |
