epithelium
Membranous tissue composed of one or more layers of cells separated by very little intercellular substance and forming the covering of most internal and external surfaces of the body and its organs.
glandular epithelium
Epithelium made up of cells that produce secretions.

What type of epithelium line the jejunum?
The jejunum is lined with simple columnar epithelium. This type of epithelium is specialized for absorption and secretion, making it well suited for the functions of this part of the small intestine.
What are the primary functions of the respiratory epithelium?
The primary functions of the respiratory epithelium are to humidify and warm the air as it enters the respiratory tract, as well as to protect the underlying tissues from pathogens and foreign particles. Additionally, the respiratory epithelium is involved in the exchange of gases, such as oxygen and carbon dioxide, between the air and the blood in the lungs.
What are the major functions of epithelium in the body and give examples.?
it protects the body
Which level of organization would be seen in the liver but not in the epithelium?
Liver tissue is made up of specialized cells that perform various functions, whereas epithelium is a single layer of cells that cover body surfaces. The level of organization seen in the liver but not in the epithelium would be the organ level, as the liver is a complex organ with multiple tissues and structures working together to perform its functions.

What are the differences between pseudostratified columnar epithelium and stratified columnar epithelium in terms of their structure and function?
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.
What are the major functions of epithelium in the body and give examples.?
it protects the body
Five major functions of epithelium in the body?
Major functions of epithelium are, protection, absorption, sensation, filtration, secretion and excretion. Also helps in regulation and exchange of chemicals between the underlying tissues and cavities.
What are the four types of epithelial tissue based on their special functions?
The four types of epithelial tissue based on their special functions are: Simple squamous epithelium, for filtration and diffusion Simple cuboidal epithelium, for absorption and secretion Simple columnar epithelium, for secretion and absorption Pseudostratified columnar epithelium, for secretion and propulsion of mucus
Most of the gi tract is composed of blank epithelium?
Most of the GI tract is composed of simple columnar epithelium. This type of epithelium is well-suited for secretion and absorption processes due to the presence of microvilli, which increase the surface area available for these functions.
What is the difference between covering and lining epithelium from glandular epithelium?
Covering epithelium covers body surfaces and components of organs, providing protection, absorption, or secretion. Lining epithelium lines cavities and tubes, serving similar functions as covering epithelium but in a different location. Glandular epithelium forms glands that secrete substances such as hormones or enzymes into the blood or cavities.
What is the functions of simple columnar with microvilli?
Simple columnar epithelium with microvilli functions to increase surface area for absorption and secretion in the intestines, where it lines the gastrointestinal tract. The microvilli on the surface of the cells further aid in the absorption of nutrients and the movement of substances across the epithelium.
What is the stratified squamous epithelium functions?
Stratified squamous epithelium consists of several layers of cells, which protect the areas of the body It can be found in areas such as the esophagus, mouth, and the outer portion of the skin (epidermis).
Which level of organization would be seen in the liver but not in the epithelium?
Liver tissue is made up of specialized cells that perform various functions, whereas epithelium is a single layer of cells that cover body surfaces. The level of organization seen in the liver but not in the epithelium would be the organ level, as the liver is a complex organ with multiple tissues and structures working together to perform its functions.
What is the function of an epithelium that is smooth on its free surface compared to an epithelium with a folded free surface made up of micro-villi?
Secretion is one of epithelium's major functions. However, if there are microvilli, they are used for absorption. Regular epithelium would be in our skin, and epithelium with microvilli would be in the digestive tract.
