(a)   – extracellular material that surrounds the cells.

(a)   – covers the body surfaces, lines body cavities, forms the linings of many organs, and makes up glands.

(a)   – between an epithelium and underlying connective tissue.

(a)   surface: surface of the cell that faces the basement membrane

(a)   surface: surface that faces away from the basement membrane

(a)   epithelia – one layer of cells.

(a)   epithelia – two or more layers of cells.

(a)   – consists mostly of fibers and ground substance.

(a)   – produce ground substance that form the matrix

(a)   (white blood cell) – have distinctive nuclei and occur in response to different conditions

(a)   – make antibodies

(a)   – secrete heparin (inhibits blood clotting) and histamine (vasodilation)

(a)   – fat cells

(a)   – made of collagen; tough & flexible and resist stretching.

(a)   – collagen fibers coated with glycoprotein

(a)   – made of elastin; stretches & recoils like a rubber band
