The gallbladder is primarily
an absorptive epithelium
that functions to concentrate sodium salts of bile acids by near-isotonic fluid absorption from the gallbladder lumen.
Why is microvilli present in gallbladder?
The inner surface of the gallbladder wall is lined with mucous-membrane tissue similar to that of the small intestine. Cells of the mucous membrane have hundreds of microscopic projections called microvilli, which
increase the area of fluid absorption
.
What is found in the gallbladder?
The gallbladder is a small pouch that sits just under the liver. The gallbladder
stores bile produced by the
liver. After meals, the gallbladder is empty and flat, like a deflated balloon. Before a meal, the gallbladder may be full of bile and about the size of a small pear.
Does the gallbladder have cilia?
Cholangiocytes, the epithelial cells lining intrahepatic bile ducts,
contain primary cilia
(fig. 2) as do most cells in the body (hepatocytes being an exception).
Which epithelium is present in stomach intestine and gallbladder?
In humans,
simple columnar epithelium cells
are mostly seen in the digestive tract including organs like the stomach, small intestine, and large intestine. It is also seen in the uterus. Simple columnar epithelium can be divided into two categories – ciliated and non-ciliated or glandular.
What cells are in gallbladder?
The gallbladder is made up of layers of tissue: mucosa – the inner layer of
epithelial cells
(epithelium) and lamina propria (loose connective tissue) a muscular layer – a layer of smooth muscle. perimuscular layer – connective tissue that covers the muscular layer.
How is bile stored in gallbladder?
From the cystic duct, bile is pushed into the gallbladder by peristalsis (muscle contractions that occur in orderly waves). Bile is then
slowly concentrated by absorption of water through the walls of the gallbladder
. The gallbladder stores this concentrated bile until it is needed to digest the next meal.

green-brown bile
and lined with a folded mucosa.
Which type of epithelium is found in the stomach?
The lining epithelium of the stomach, and gastric pits is entirely made up of
mucous columnar cells
. These cells produce a thick coating of mucus, that protects the gastric mucosa from acid and enzymes in the lumen. Even so, these cells have to be replaced after 4-6 days.
What type of epithelial tissue is found in the small intestine?
6.7. 6 GUT Epithelium. The inner lining of the colon and small intestine is a
simple columnar epithelium
constantly renewed by the proliferation of stem cells residing within pockets, or crypts, along the intestinal wall.

simple columnar epithelium
.
