Whether the lumen of the digestive tract is located on the apical side or basolateral side of the intestinal epithelium. Introduction: The digestive system initiates with the oral cavity consisting of the pharynx and mouth. This oral activity acts as the receptacle for food. After the food is swallowed, it enters the gastrointestinal tract. The gastrointestinal tract comprises stomach, oesophagus, large intestine, and the small intestine.

Question

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Expert Solution

Explanation of Solution

The lumen of the digestive tract is located on the apical side of the intestinal epithelium. The apical side of the intestine is covered with microvilli, which increases the surface area for absorption. Partially digested food enters into the small intestine from the stomach and small intestine digest it properly and absorbs the nutrient.

Conclusion

The lumen of the digestive tract is located on the apical side of the intestinal epithelium.

Summary Introduction

To determine: Whether the lumen of the digestive tract is located on the serosal side or mucosal side of the intestinal epithelium.

Introduction: The length of the small intestine of humans is about 20 feet long. Small intestine lies between the stomach, and large intestine and its primary function of the small intestine is the absorption of the food.

Expert Solution

Explanation of Solution

The lumen of the digestive tract is located on the mucosal side of the intestinal epithelium. Mucosal cells comprise transporting epithelial cells, the exocrine and endocrine secretory cells as well as stem cells. The epithelial cells are also called enterocytes in the small intestine. The cells secrete mucus, ions, paracrine molecules, and enzymes into the lumen at the apical and mucosal surface of the epithelium.

Conclusion

The lumen of the digestive tract is located on the mucosal side of the intestinal epithelium.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?

Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to. What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?

Does the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo? Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?
