The purpose of epithelial tissues?
Epithelial tissues performs the following functions:1. ProtectionEpithelial tissue provides physical protection of exposed structures from:abrasionbiological agentschemicalsdehydrationdestruction2. Control permeabilitySubstances that enter or exit the body usually have to travel across an epithelial barrier. Epithelial tissues may be permeable or selectively permeable (only letting certain substances through and not others)3. SensationNeuroepithelium is a specialized type of epitheliun with a large sensory nerve supply allowing it to provide sensations such as:hearingsightsmelltasteequilibrium (balance)4. SecretionSome epithelial tissue is specialized to produce secretions.
Which type of epithelial tissue is used in areas where diffusion is a main function?
Diffusion occurs across simple epithelial tissue. These are only one layer.
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
cilia
What membrane components allow movement of non-polar substances across membrane?
Integral proteins allow movement of non-polar substances across membranes.
What term identifies the concept that some substances can move freely across a cell membrane while other substances must be carried across by proteins?

What tissue forms the inner lining of the respiratory passages?
The type of epithelial tissue that lines much of the respiratory tract is called pseudostratified columnar. This type of tissue also moves substances across its surface.
How can substances move across capillaries?
Substances typically move across capillaries via diffusion.
Which type of epithelial tissue is used in areas where diffusion is a main function?
Diffusion occurs across simple epithelial tissue. These are only one layer.
How do gases get into and out of the blood?
Via Diffusion across the EPITHELIAL CELL LININGS of the Alveoli.
How do larger molecules move across epithelial membranes in capillaries?
by exocytosis and endocytosis
What best explain the passage of air across alveolar membranes?
diffusion, through moist thin, epithelial cells
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
cilia
How did R2D2 travel across sand?
Most droids can move across a variety of surfaces with ease
At what speed do most amtrak sleeper cars travel across country?
Each sleeper car travels at the speed of the locomotive that propels it.
