• white blood cells
• found in connective tissue

lymphocytes turn into plasma cells when they detect foreign objects the plasma cells synthesize disease fighting proteins called antibodies

found alongside blood vessels secrete heparin that inhibits blood clotting, and one called histamine that increase blood flow

fat cells small clussters in some fibrous connective tissues also known as adipose tissue

made of collagen they are tough and flexible and resist stretching

thin collagen fibers coated with glycoprotien

thinner then collagen fibers made of protien called elastin it strectches and recoils like rubber bands

much of the space is occupied , leaves empty space in in prepared tissue sections.

occupies more space appears closely packed

exhibits loosely organized fibers , posseses all six of the cell types

a mesh of reticular fibers and forblasts

collagen fibers closely packed and leave little open space, fibers are parallel to each other

thick bundles of collagen and relatively little room for cells and ground substance but the in random collagen bundles run in random directions

clear glassy appearance

supportive connective tissuewith flexible rubbery matrix

conspicuous elastic fibers

fills the head of long bones, forms middle layers of flat bones

calcified tissue with no spaces visible to naked eye

cell or organ that secretes substances for uses else where in the body or releases them from the body

maintains contact with the surface by way of duct

lose there contact with the surface and have no ducts

composed of simple squamous epithelium resting on a thin layer of areolar connective tissue

shrinkage of a tissue through loss in cell size or number

the premature death of tissue due to trauma toxins infection

sudden death of tissue
