animal tissue Flashcards
a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material.
Tissues
4 basic types of tissue
connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
supports other tissues and binds them together
connective tissue
provides a covering
epithelial tissue
includes striated muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach.
Muscle tissue
made up of nerve cells and is used to carry “messages” to and from various parts of the body.
Nerve tissue
Tightly-joined closely-packed cells
One side of epithelium exposed to air or internal fluid, other side attached to a basement membrane, a dense mat of extracellular matrix (connective tissue)
Covers the outside of the body and lines the internal organs and cavities
Barrier against mechanical injury, invasive microorganisms, and fluid loss
Provides surface for absorption, excretion and transport of molecules
Epithelial Tissue
type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands.
Epithelial Tissue
Location:Air sacs of the lungs, kidney glomeruli, lining of the heart, blood vessels, and lymphatic vessels.
Function: Allows passage of materials by diffusion and filtration
Simple Squamous Epithelium
Location: Kidney tubules, ducts and small glands, and a surface of
ovary.
Function: Secretion
Simple Cuboidal Epithelium
Location: Lines of digestive tract, gallbladder and excretory ducts of some glands.
Function: Absorption, enzyme secretion
Simple Columnar Epithelium
Location: Lines the bronchi, uterine tubes and some regions of the uterus.
Function: Propels mucus or reproductive cells by ciliary action.
Pseudostratified Ciliated Columnar Epithelium
Location: Lines the esophagus, mouth, and vagina. Keratinized variety lines the surface of the skin.
Function: Protects underlying tissues in areas subject to abrasion
Stratified Squamous
Epithelium
bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. They occur throughout the body.
Connective tissues
Location: Around kidneys,
under the skin, in bones,
within abdomen, and in
breasts.
Function: Provides reserve
fuel (lipids), insulates against
heat loss, and supports and
protects organs.
