|
an integrated group of similar cells that perform a common function
|
tissue
|
|
|
made up of two or more tissues that together perform a specific task
|
organ
|
|
|
contains a number of organ systems, each specialized for certain functions and all functioning together as an integrated, coordinated unit
|
organism
|
|
|
What are the four main animal tissues?
|
epithelial tissue
connective tissue muscle tissue nervous tissue |
|
|
occurs as sheets of tightly packed cells that cover body surfaces and line internal organs and cavities
|
epithelial tissue
or epithelium |
|
|
The basal surface of an epithelium is attached to a _____, a dense mat of extracellular matrix consisting of fibrous proteins and sticky polysaccharides that seperates the epithelium from other tissues. Forms a protective barrier and surface for exchange
|
basal lamina
|
|
|
A ___ epithelium has a single layer of cells, whereas a ____ epthelium has multiple layers. A _____ epithelium is single layered but appears stratified because the cells vary in length. The shape of the cells maybe _____ (flat), _____ (like dice), or ____ (like bricks on end)
|
simple
stratified pseudostratified squamous cuboidal columnar |
|
|
____ ____ epithelium is thin and suitable fro exchanging materials by diffusion
|
simple squamous
|
|
|
Both ____ and ____ epithelia have cells with relatively large amount of cytoplasm, facilitating their role of secretion and absorbtion of materials.
|
cuboidal and columnar
|
|
|
Forms mucous membranes that line the respiratory tract.
|
psuedostratified ciliated columnar epithelium
|
|
|
well suited for lining surfaces subject to abrasion (such as skin)
|
stratified squamous epithelium
|
|
|
most common connective tissue in the human body
its matrix is a loose weave of fibers...serves mainly as binding and packing material holding other tissues and organs in place |
loose connective tissue
|
|
|
has a matrix of densely packed packed parallel bundles of collagen fibers...non elastic strength...forms tendons, which attach muscles to bone, and ligaments, which join bones together
|
fibrous connective tissue
|
|
|
stores fat in large, closely packed ____ cells held in a sparse matrix of fbers...pads and insulates the body and stores energy
|
adipose tissue
|
|
|
is found throughout the body. It has 3 main components; cells, fibers, and extracellular matrix...divided into 6 major types
|
connective tissue
|
|
|
consists of an abundance of collagen fibres embedded in a rubbery material...covers ends of bones and supports the nose and ears...shock absorbing surface
|
cartilage
|
|
|
has a matrix of collagen fibres embedded in a hard mineral substance made of calcium, magnesium, and phosphate...contains living cells
|
bone
|
|
|
extracellular matrix is a liquid called plasma that consists of water, salt and dissolved proteins...involved in immunity and transport
|
blood
|
|
|
name the six types of connective tissue
|
loose connective tissue
fibrous connective tissue adipose tissue cartilage bone blood |
|
|
attached to bones by tendons and is responsible for voluntary movements of the body...striated
|
skeletal muscle
|
|
|
forms contactile tissue of the heart...striated...cells are branched, interconnecting at specialized junctions that rapidly relay the signal to contract from cell to cell during the heartbeat
|
cardiac muscle
|
|
|
found in the walls of the digestive tract, urinary bladder, arteries, and other internal organs...responsible for involuntary activities...contract more often and more slowly than striated muscle...spindle structure
|
smooth muscle
|
|
|
senses stimuli and rapidly transmits information from one part of an animal to another
|
nervous tissue
|
|
|
protects against mechanical injury, infection, excesssive heat or cold, and drying out
|
integumentary system
|
