Tissues |
an integrated group of cells with a common function, structure, or both |
|
Epithelial Tissue |
sheets of tightly packed cells that line organs and body cavities |
|
Glandular Epithelia |
an epithelium that absorbs or secretes chemical solutions |
|
Mucous Membrane |
smooth moist epithelium that lines the digestive tract and air tubes leading to the lungs |
|
Simple Epithelium |
an epithelium consisting of a single layer of cells that all touch the basal lamina |
|
Stratified Epithelium |
an epithelium consisting of more than one layer of cells in which some but not all cells touch the basal lamina |
|
Cuboidal |
the cubic shape of a type of epithelial cell |
|
Columnar |
the column shape of a type of epithelial cell |
|
Squamous |
the flat, tile-like shape of a type of epithelial cell |
|
Connective Tissue |
animal tissue that functions mainly to bind and support other tissues, having a sparse population scattered through an extracellular matrix |
|
Collagenous Fibers |
A tough fiber of the extracellular matrix. Collagenous fibers are made of collagen, are nonelastic, and do not tear easily when pulled lengthwise. |
|
Elastic Fibers |
A long thread made of the protein elastin. Elastic fibers provide a rubbery quality to the extracellular matrix that complements the nonelastic strength of collagenous fibers. |
|
Reticular Fibers |
A very thin and branched fiber made of collagen. Reticular fibers form a tightly woven fabric that is continuous with the collagenous fibers of the extracellular matrix. |
|
Fibroblasts |
a type of cell in loose connective tissue that secretes the protein ingredients of the extracellular fibers |
|
Macrophages |
a phagocytic cell present in many tissues that functions in innate immunity by destroying microbes and in acquired immunity as an antigen-presenting cell |
|
Muscle Tissue |
tissue consisting of long muscle cells that are capable of contracting when stimulated by nerve impulses |
|
Nervous Tissue |
tissue made up of neurons and supportive cells |
|
Organs |
a specialized center of body function composed of several different types of tissues |
|
Mesenteries |
a membrane that suspends many of the organs of vertebrates inside fluid-filled body cavities |
|
Thoracic Activity |
the body cavity in mammals that houses the lungs and heart. It is surrounded in part by ribs and separated from the lower abdominal cavity by the diaphragm. |
|
Abdominal Cavity |
the body cavity in mammals that primarily houses parts of the digestive, excretory, and reproductive systems. It is separated from the thoracic cavity by the diaphragm. |
|
Organ Systems |
a group of organs that work together in performing vital body functions |
