Animal Tissues & Organ Systems - T4 S1 Flashcards
___ can grow tissues outside of the body.
Tissue engineering
___ cells build animal bodies.
Specialized
study of an organism’s structure, describes the parts that compose the body
anatomy
considers how those parts that compose the body work
physiology
How many tissue types to animals consist of?
4
All animal tissues have what feature in common?
cells embedded in extracellular matrix; ground substance and fibers
animal tissue type:
single or multiple layer of flattened, cube-shaped, or columnar cells
epithelial
animal tissue type:
cover interior and exterior surfaces of organs; protection; secretion; absorption
epithelial
animal tissue type:
cells scattered in prominent extracellular matrix
corrective
animal tissue type:
support, adhesion, insulation, attachment, and transportation
corrective
animal tissue type:
elongated cells that contract when stimulated
muscle
animal tissue type:
functions in movement
muscle
animal tissue type:
cells that transmit electrochemical impulses
nervous
animal tissue type:
rapid communication among cells
nervous
tissue that covers surfaces, 1/more layers of tightly packed cells, functions: protection/nutrient absorption/gas diffusion, form glands, “free” surface, anchored by basement membrane, may be joined by tight junctions
epithelial
90% of cancers are ___.
carcinomas
What are epithelial tissues classified by?
cell shape,
number of layers
epithelial tissue type:
single layer of flattened cells; allows substances to pass by diffusion and osmosis; lining of blood vessels, alveoli of lungs, glomeruli of kidneys
simple squamous
epithelial tissue type:
single layer of cube-shaped cells; secretes and absorbs substances; glands, lining of kidney tubules
simple cuboidal
epithelial tissue type:
single layer of column-shaped cells, may be ciliated; secretes and absorbs substances, sweeps egg/embryo along uterine tube; lining of digestive tract, bronchi (ciliated), uterine tubes (ciliated)
simple columnar
epithelial tissue type:
multiple layers of flattened cells; protects areas subject to abrasion, prevents water loss and infection; outer layer of skin, lining of body openings
stratified squamous
epithelial tissue type:
multiple layers of cube-shaped; conveys sweat, secretes hormones; sweat gland duct, ovaries
stratified cuboidal
epithelial tissue type:
single layer of columnar cells with staggered nuclei, may be ciliated; secretes and propels mucus; upper respiratory tract (ciliated)
pseudostratified columnar
tissues that bind other tissues together; most widespread tissue; scattered w/in extracellular matrix; functions- fill spaces, attach tissues, cushion, flexible but firm support; never coat surfaces; extremely variable in structure and function
connective tissue
