2) WHAT IS THE LINING OF SMALL INTESTINE MADE UP IS?
3) WHERE ARE THE EPETHELIAL CELLS WITH CILIA FOUND?
Answers
Answer:
1 )Endothelium refers to cells that line the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. It is a thin layer of simple, or single-layered, squamous cells called endothelial cells.
2)The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue. Structurally, the mucosa is covered in wrinkles or folds called plicae circulares, which are considered permanent features in the wall of the organ.
3)It often occurs in the vicinity of mucus-secreting goblet cells. These hairs, called cilia, move back and forth to help move particles out of our body. We find ciliated epithelial tissue in our respiratory tract and in the fallopian tubes of women. Ciliated epithelium contains goblet cells, which secrete mucous.
