Structure and function of the airway?
The airway of the respiratory system is mainly to do with the trachea, bronchi, bronchioles and the alveoli duct. Trachea composes of Pseudostratified columnar, ciliated epithelium, Goblet cells, Sero-mucous glands and Cartilage rings. Its main function is to allow air to pass and reach the bronchioles and to trap dust by the presence of the cilia lining its epithelium membrane. The bronchi is composed of Pseudostratified columnar, ciliated epithelium (shorter), Goblet cells (fewer), Sero-mucous glands, Cartilage, Smooth muscle. main function is to bring air into the lungs because their walls are too thick to permit gass exchange. The bronchioles is made up of Simple columnar or cuboidal & ciliated epithelium,No goblet cells,Smooth muscle (relatively abundant), Clara cells is to permit the movement of gas int the alveoli duct in-order for gaseous exchange to take place.
What is the function of transitional epithelium in the bladder?
Transitional epithelium consists of multiple layers of epithelial cells which can contract and expand. Its primary function is to elongate when the bladder starts to fill, allowing an increase in bladder volume.
Where is connective tissues located?
Loose connective tissue is found beneath epithelial membranes and glandular epithelium. The function of the loose connective tissue attaches to the epithelium to underlying tissues and allow for diffusion of nutrients to epithelial cells.
Why can filtration be used to sterilize culture media?
Sterility can be achieved with filtration as filtration will allow the positive bacteria to sift through, while the negative harmful bacteria will be pulled out and separated from the organism as it once was.
A type of epithelium consisting of a single layer of flat cells which allow diffusion to occur is?
This is referred to as the simple squamous epithelium. These cells contact the basement membrane and they are flat and thin.

What is the connection between the shape and the function of epithelium tissue?
thin wall - rapid diffusion small gaps - allow diffusion and actv tspt goblet cells in lung epithelium - secrete mucus to trap bacteria ciliated epithelium - waft mucus out of the lungs squamous - stretch and recoil around a blood vessel there are about another 10 types of specialised epithelium tissues and cells in the human body

What is a structural characteristic of squamous epithelium?
There is different types of squamous epithelium: simple and stratified. The function of simple squamous epithelium:It is good for the passage of materials via diffusion. For example, it forms the tiny air sacs of the lungs and the walls of capillaries. It also forms the smooth, friction-reducing interior lining of the heart, blood vessels, thoracic cavity, and abdominal cavity. The function of the stratifed squamous epithelium: It functions to protect underlying tissues in areas subjected to abrasion. The keratinized type forms the outermost layer of the skin, where it functions to prevent water loss. The nonkeratinized variety forms the moist linings of the mouth,esophagus, anus, vagina.
What two urinary bladder structures allow for expansion?
rugae and transitional epithelium

What is the process of filtration?
The process of coolant filtration is actually a somewhat complicated process. Basically though the coolant filters allow recirculation and reuse of liquid coolant.

How does the epithelia of esophagus relate to its function?
The epithelium is non-keratinized stratified squamous epithelium with scattered mucus glands. Let's go through each of these characteristics: Stratified - Many cells so that friction from esophageal objects does not scrape off deep cells. Squamous - Flat cells that allow sloughing off and closer packing Mucus Glands - Lubricate the passage of food down esophagus All these things help the function of esophagus to transfer food from mouth to stomach!
What is it about the epithelium nature of cells that keeps oxygen from diffusing into our bodies through the skin?
The cells in the skin epithelium are cuboid, mostly dead, with very low vascularity and saturated with keratin which prevents not only gases from diffusing in and out of the body, but also prevents liquids and solutes from moving out of the body. There are, anyway, epithelia that allow oxygen flow, like the lung's epithelium, since epithelium is a kind of tissue that covers others, therefore, not only skin is epithelium.
