Since epithelium needs to serve as both a barrier and selectively permeable membrane, the cells need to be tightly junctioned to one another (thus prohibiting paracellular transport) and need to express channels, transporters or exchangers to allow for movement of selected ions/molecules across the epithelial barrier
The avascularity of epithelium and cartilage reduces the risk of bleeding in case of injury. It also helps maintain a stable environment for cell function and tissue structure.
The dominant function of stratified epithelium is to protect underlying structures from mechanical wear and tear.
Ciliated epithelium is found in areas where movement of particles, such as mucus and debris, is important. It is commonly found in the respiratory tract, fallopian tubes, and parts of the reproductive system. The cilia help to move substances along the surface of the epithelium.

The fallopian tubes are lined by a ciliated epithelium in females. The cilia help move the egg from the ovary to the uterus for potential fertilization.

This type of epithelium is frequently found in glands, and the pancreas, where its function is secretion.
The dominant function of stratified epithelium is to protect underlying structures from mechanical wear and tear.

Pseudostratified columnar epithelium is a single layer of cells that appear to be layered due to varying cell heights, while stratified columnar epithelium has multiple layers of cells. Pseudostratified columnar epithelium is found in the respiratory tract and functions in secretion and absorption, while stratified columnar epithelium is found in the male urethra and functions in protection.

The structure in the lungs that contains the thinnest epithelium is the alveoli. Alveoli are air sacs where the exchange of gases takes place.
Simple squamous epithelium has the shortest diffusion distance due to its thin structure, allowing for rapid diffusion of substances across the epithelium.
The structure of transitional epithelium is that it has several layers of epithelial cells that can contract and stretch. It is has a cube-like shape when not stretched and appears flat when stretched.

The function of the gallbladder is to store bile produced by the liver
