The salivary glands are composed of which two types of cells?
The salivary glands are composed of two types of cells: serous cells, which produce a watery secretion rich in enzymes, and mucous cells, which produce a thicker, more viscous secretion containing mucin. These cells work together to produce saliva, which helps in the process of digestion.
What cells are in a simple columnar and pseudostratified columnar epithelia produce protective mucous coatings over the mucous membranes?
Goblet cells are the cells in both simple columnar and pseudostratified columnar epithelia that produce protective mucous coatings over mucous membranes. These cells secrete mucus, which helps to lubricate and protect the surface of the tissues from damage, dehydration, and invasion by pathogens.
The acinar cells of pancraes produce?
The acinar cells of the pancreas produce digestive enzymes that are released into the small intestine to help break down proteins, fats, and carbohydrates in the food we eat, aiding in their digestion and absorption.
Why are the cells of mucous membrane are open to virus attacks?
The cells of mucous membranes are open to virus attacks because they are not covered by a skin.
What lines the nasal cavities?
The nasal cavities are lined with mucous membranes, which produce mucus to help trap and remove dirt, pathogens, and other particles from the air we breathe. These membranes also contain cilia, tiny hair-like structures that help move the mucus and trapped particles towards the throat for removal.

What are cells abundant within the large intestine called that produce large amounts of lubricating mucus to aid in the passage of feces to the end of the digestive tract?
goblet cells
What is lined with mucous-secreting cells called the mucosa.?
The Stomach
Does the large intestine have villi?
The answer is small intestine.
The structures that produce new cells for the mucosa of the small intestine are the?
Intestinal Crypts
Which of these is lined with mucous-secreting cells called the mucosa?
esophagus Every system that has an outside opening produces mucous. This includes the respiratory, urinary, digestive and urogenital systems. Also the lining of the eye produces mucous. This substance keeps the membranes moist and prevents them from drying out.
What type of tissue is mucous?
mucous cells
What does the intestine wall made of?
Epithelial cells called villi
What are the Crypts of lieberkuhn?
The Crypts of Lieberkühn, named after the anatomist Johann Nathanael Lieberkühn, are invaginations found in the lining of the small intestine. These crypts house stem cells that continuously replenish the epithelial cells of the intestinal lining. They also produce mucous that helps protect the intestinal wall from digestive enzymes.
Is mucous membranes sterile?
Mucous membranes are not sterile as they are lined with cells that produce mucus and harbor bacteria and other microorganisms. The presence of commensal bacteria helps maintain the balance of the microbiome and supports the immune system.
Mucous that protects your stomach lining is secreted by a specialized type of?
Mucous that protects the stomach lining is secreted by specialized cells called goblet cells. These cells are found throughout the stomach and are responsible for producing and releasing the mucous layer that helps to protect the stomach from the acidic environment and enzymes.
