Simple epithelial cells.
The type of epithelial tissue that lines the digestive tract and contains mucus-secreting goblet cells is simple columnar epithelium. This tissue is specialized for absorption and secretion, playing a crucial role in protecting the intestinal lining and facilitating the movement of food through the digestive system. The mucus produced by the goblet cells helps to lubricate the digestive tract and protect it from digestive acids and enzymes.
Goblet cells are a type of epithelial cell found in mucous membranes throughout the body, such as the respiratory and digestive tracts. They secrete mucus to help protect and lubricate these surfaces.
The epithelial membrane called the mucosa contains the lamina propria. The salivary glands are composed of serous cells and mucous cells.
The digestive tract is primarily lined with epithelial cells, specifically simple columnar epithelium, which facilitates absorption and secretion. Specialized cells, such as goblet cells, produce mucus to lubricate and protect the lining. In areas like the stomach, gastric pits contain secretory cells that produce digestive enzymes and acids. Additionally, the digestive tract contains enteroendocrine cells that release hormones to regulate digestion.
They are modifications of simple columnar epithelial tissue.
Simple.
The Wine glass shaped cells that secrete mucus are called "goblet cells". These are simple columnar epithelial cells found scattered among the epithelial linings of intestine and respiratory tract.
Cells in the lungs and digestive tract are designed to be simple (single-layered) rather than stratified (multi-layered) to facilitate efficient gas exchange and nutrient absorption. Simple epithelial cells allow for rapid diffusion of oxygen and carbon dioxide in the lungs, and enable the efficient transport of nutrients and waste in the digestive tract. Stratified layers would hinder these processes due to increased distance and reduced permeability. Thus, the simple structure optimizes function in both organs.
