Epithelial Tissue Flashcards
Name the 4 structural differences in epithelial tissue.
Simple aquamous, simple cuboidal, simple columnar, pseudostratified columnar.
Additional features of epithelial tissue.
Can be covered in small like hair projections called cilia. Can help move dust and mucus.
About epithelial tissue.
It is supported by a basement membrane and can consist of a simple or stratified layer of cells. The basement membrane consists of a network of blood vessels, providing oxygen and nutrients to the cell allowing for absorption . Secretory epithelial are specialised to secrete substances such as proteins for example goblet cells.
Function and location of the aquamous.
It allows substances to diffuse across. It is found in the alveoli
Functions and location of the cuboidal.
It allows the diffusion and secretion of molecule. It is found in the lines of the kidney tubules.
Functions and location of the columnar.
It allows for nutrient absorption and secretion of substances such as mucus. It is found in the lines of the small intestines.
Function and location of the pseudostratified columnar.
It allows for impurities to be swept towards the throat due to secretion of mucus. It is found in the lines of the trachea.
