Crohn disease causes inflammatory reactions that damage the lining of the intestines. In areas where attacks are occurring, the inflammation can cause damage to the entire lining, so that the contents of the lumen of the intestine are exposed to, for example, the peritoneal cavity. Describe the layers that this inflammation would need to penetrate in order to damage the entire wall of the intestine. Inflammation begins at the epithelial lining.

- The smooth muscle cells are arranged in two different ways in intestinal wall. Explain the significance of two different arrangements of smooth muscle cells in intestinal wall i.e. how these arrangements relate to the function.Which is a correct statement about the Na+/K+ transporter (pump), and its cytology and cellular role? It is found the basal side of intestinal epithelial cells, pumping Na+ out of the cell into the blood. It is found on the plasma membrane of neurons, pumping Na+ into axons from the blood. It is found on the membrane of the lysosome, pumping K+ into the lumen of the lysosome. It is found on the apical side of intestinal epithelia, pumping K+ into the lumen of the intestine.State the change in lining epithelium of the pylorus(stomach) to the duodenum (small intestine). Explain in long explanation
- Put the following terms in their correct order from the simplest to the most complex. Skin cell, Integumentary system , Epithelial tissue, Stem cell , Skin, Organism The stomach produces hydrochloric acid which increases the acidity of the stomach to digest the food. However, the small intestine are not damaged by strongly acidic food coming from the stomach. How does our body avoids damaging the small intestine with this strongly acidic food passes out of the stomach?Some of the intestinal epithelial cells, called goblet cells, contain small globules of mucus. Why are there cells in the small intestine that produce mucus?The Alimentary Canal is lined with Epithelium. For each section, esophagus, stomach, small intestine, large intestine, indicate what type of Epithelial Tissue is present and what its function is beyond a functional barrier.
- According to the definition, structure and functions of epithelial tissues, the small intestine: * O O Has the same epithelium with the gallbladder (simple columnar), but not gland type Not unicellular,has a secretory portions and ducts that branch repeatedly Itis simple gland which their secretions are transported to the target site by the blood Considers a multicellular, tubular gland and belongs to simple glands with unbranched ductThe lips are muscular folds forming the anterior boundary of the oral cavity. A mucous membrane covers the lips internally and the skin of the face covers them externally. The vermillion border, which is the red part of the lips, is covered by keratinized epithelium that is the transition between the epithelium of the mucous membrane and the facial skin. The vermillion border can become chapped (dry and cracked), whereas the mucous membrane and the facial skin do not. Propose as many reasons as you can to explain why the vermillion border is more prone to drying than the mucous membrane or facial skin.When dust particles land in the mucous escalator, __________. Group of answer choices choose one answer the dust particle sticks in the mucous secreted by type II cells then ciliated cells move the dust particle to the pharynx where it is swallowed the dust particle sticks in the mucous secreted by goblet cells then macrophages engulf the particle the dust particle sticks in the mucous secreted by goblet cells then ciliated cells move the dust particle to the pharynx where it is swallowed the dust particle sticks in the mucous secreted by type II cells then macrophages engulf the particle
- What changes would you expect to observe in the liver at the tissue level of a patient with a chronic viral infection? what are the long term implications for the patient if left untreated and how would this affect tissue function?Explain how Vibrio cholerae causes cholera without apparent damage to the intestinal epithelium. a. This microbe attaches to the surface of intestinal epithelial cells, producing an endotoxin that causes the epithelium to secrete potassium ions. This induces small amounts of water to follow by osmosis, resulting in the watery rice-stool characteristic of the illness. b. This microbe causes destruction of the cellular structures underneath the intestinal epithelium—this is what induces the watery rice-stool characteristic of the illness. This leaves the overlying intestinal epithelium intact. c. This microbe directly invades the intestinal epithelial cells, but does not kill them. Instead, while multiplying inside them, it causes them to secrete large amounts of chloride ions. This induces water to follow by osmosis, resulting in the watery rice-stool characteristic of the illness. d. This microbe attaches to the surface of intestinal epithelial cells, producing an exotoxin…How might a person be affected if all the microorganisms living in their intestines died?
