Tissues
|
group of similar cells that work together to perform the same function
|
|
|
4 types of tissues
|
epithelial, connective, muscle, nervous
|
|
|
epithelial Tissue locatione
|
surface of skin and body cavities, lowest layer bound to connective tissue by basement membrane
|
|
|
epithilialtissue functions
|
linings, passage of substances, protection
|
|
|
Simple Squamous
|
one layer scale like cells used for transportation in lungs heart and blood vessels
|
|
|
simple cuboidal
|
one layer cube shaped cells used for secretion in glands
|
|
|
simple columnar
|
one layer of rectangular cells for absorption and secretion of digestive juices in GI tract
|
|
|
goblet cells
|
in simple columnar, secretes mucus
|
|
|
microvilli
|
increases surfaces of columnar cells to aid in absorption
|
|
|
pseudostratified columnar
|
one layer columnar but looks bigger moves mucus using cilia located in respitory tract
|
|
|
Stratified Squamos
|
several layers of scale like cells to protect from microbes at the surface of the skin. Thickest epithelial tissue
|
|
|
Stratified Transitional
|
tissues that stretch and have a variety of layers and shapes e.g. bladder
|
|
|
Connective Tissue
|
most abundant tissue few cells present in tissue has an extracellular matrix
|
|
|
Extracellular Matrix
|
outside cell in connective tissue contains interstitial tissue gel and fibers
|
|
|
Areolar
|
loose tissue of gel and webs of fibers gives internal organs shape and support
|
|
|
Adipose
|
stores fat inside cells cannot remove these cells
|
|
|
Dense Fibrous
|
Parallel bundles of collagen fibers strong and flexible in tendons and ligaments
|
|
|
Bone
|
Circular arrangement of hard matrix and cells support, protection calcium storage, calcified
|
|
|
Cartilage
|
cells called chondrocytes, gristle like matrix, shape, enables smooth movement at joints/ends of bones.
|
|
|
Blood
|
liquid matrix, erythocytes, leukocytes, thrombocytes, used for transportation and protection
|
|
|
liquid matrix
|
plasma
|
|
|
erythrocytes
|
Red blood cells
|
|
|
leukocytes
|
white blood cells
|
|
|
thrombocytes
|
platlets
|
