Simple columnar epithelium is "simple" (what does this mean?) and its shape is columnar (more tall than wide). You can see goblet cells interspersed among the columnar cells. What is a goblet cell and what does it secrete?
This is a transverse (cross) section of the stomach, and you will see serval type of tissue that go together to make up the organ. Do you see the lumen of the stomach?
Where is the epithelium located?
In what other places of the body do you find this type of tissue?
What is the function of this type of tissue?
The term "simple" in simple columnar epithelium refers to the fact that it consists of a single layer of cells. The shape of the cells is columnar, meaning they are taller than they are wide.
A goblet cell is a specialized columnar epithelial cell that is shaped like a goblet or cup. Goblet cells secrete mucus, which helps lubricate and protect the epithelial surface.
In the transverse section of the stomach, the lumen of the stomach refers to the central hollow space within the organ where food is contained.
The epithelium is located on the inner surface of the stomach, lining the stomach wall.
Simple columnar epithelium can be found in various locations throughout the body, such as the intestines, gallbladder, uterus, and respiratory tract.
The function of this type of tissue is mainly secretion and absorption. The tall columnar cells and presence of goblet cells allow for efficient secretion of mucus and absorption of nutrients across the epithelial layer.
