Epithelium Tissue Flashcards
Everything
What is epithelium tissue used for
Covering and lining
Kinds of epithelium tissue
Simple epithelium-has one layer of cells
Stratified epithelium-has several layers of cells
What is innermost layer of epithelium cells attached to
A sheet of protein called the basement
Where is squamous epithelium located?
Lines internal walls of cavities(mouth and heart)
What is the function of squamous epithelium
Permeable to gases
Prevents friction
Protects
Characteristics of squamous epithelium
Cells are flattened for enable easy diffusion of substances
Forms walls of alveoli in the lungs- ensures easy exchange of gases between the blood and air
Irregular sharp and flat nucleus
Forms walls of capillary vessels(endothelium) makes easy for diffusion of substances between blood and the tissue fluid
Where is cubodial epithelium located
Lining of glands
What is the function of cubodial epithelium
Secretion
Absorption
Characteristics of cubodial epithelium
Found in lining of thyloid,salivary and sweat glands
Forms walls of tubules in kidneys where reabsorption of water takes place
Where is columnar epithelium located
Linens alimentary canal,taste buds
Goblet cells-secretes mucus
Function of columnar epithelium
Secretion
Absorption
Sensation
Characteristics of columnar epithelium
Often contains goblet cells for lubrication
Lines the entire alimentarh canal
Where is ciliated epithelium located
Linens nasal cavity,trachea,ear,fallopian tube
Goblet cells -secretes mucus
Function of ciliated epithelium
Secretion
Absorption
Characteristics of ciliated epithelium
Contains goblet cells plus cilia
Mucus traps dust in inhaled air and cilia causes movement to proper mucus upwards away from lungs
