What else can I help you with?
What is lubricant for food as it passes through the alimentary canal?
Mucus produced by cells which line the digestive tract.
Why do cells in your stomach and intestine divide so often?
Cells in the stomach and intestine divide frequently to replace old or damaged cells, maintain the integrity of the digestive lining, and support the functionality of the digestive system. This rapid division process ensures that the lining of the stomach and intestine stays healthy and can continue to carry out their vital functions in absorbing nutrients and digesting food.
Which histological layer of the digestive tract is composed primarily of epithelial tissue?
The epithelial tissue is primarily found in the mucosa layer of the digestive tract. This layer consists of epithelial cells that line the inner surface of the tract, providing a protective barrier and facilitating absorption of nutrients.
What lines the digestive and respiratory tract?
Mucous membranes line the digestive and respiratory tracts.
How do Enterobacterial infections start?
Enterobacterial infections in the digestive tract typically start when the organisms invade the mucous tissues that line the digestive tract
What are the jobs of epithelial tissues?
Epithelial tissues are sheets of tightly packed cells that line organs and body cavities.
Which of the following cell types are least likely to reproduce endothelial cells that line the digestive system fibroblasts of connective tissue skeletal muscle tissues red bone marrow cells?
sceletal muscle tissue
What role does tissue and cell play in digestion?
Tissues in the digestive system, like the mucosa and submucosa, help with nutrient absorption and secretion of digestive enzymes. Cells such as epithelial cells line the gastrointestinal tract and aid in nutrient transport. Overall, tissues and cells work together to facilitate digestion, absorption, and processing of nutrients in the body.
Where are the stem cells that make new cells to protect the intestines in an adult?
In the adult intestines, the stem cells that generate new cells to protect the tissues are located in the intestinal crypts. These stem cells are found at the base of the crypts and continuously divide to produce new cells that migrate upwards to replace the older cells that line the intestinal surface.
List the cells of the digestive systems?
The cells that are present in the human digestive system areMucosa - the layer that absorbs and secretes is made up of simple epithilium cells and connective tissue. There are specialized goblet cells that secrete mucus throughout the gastro intestinal tract located within the mucosa. On the mucoas there are the villi and microvilli.Submucosa that is thick and vascular. It also has glands and nerve plexuses.Mucscularis has inner circular layer and outer longitudinal layer of smooth muscle cells.Serosa is a protective layer composed of avascular connective tissue and squamous epithelium cells.
How does th bacteria reproduce in the digestive system?
Digestive bacteria reproduce by a process called Binary fission, which simply means one cell divided to become two cells, then those two cells become four, four become eight, etc the same way you do. Skin is the first line of defense and it work as physical barrier for all the microbes and particle. Skin has many secretory products which kill the bacteria also.
Is a stomach a nervous tissue?
No, the stomach is not composed of nervous tissue. It is primarily made up of muscle tissue, connective tissue, and epithelial cells that line the digestive tract. Nervous tissue is found in the form of nerve fibers that innervate the stomach to regulate its functions.
