C.circular folds
asap
Step by step
Solved in 2 steps
- Figure 34.12 Which of the following statements about the small intestine is false? Absorptive cells that line the small intestine have microvilli, small projections that increase surface area and aid in the absorption of food. The inside of the small intestine has many folds, called villi. Microvilli are lined with blood vessels as well as lymphatic vessels. The inside of the small intestine is called the lumen.Figure 34.11 Which of the following statements about the digestive system is false? Chyme is a mixture of food and digestive juices that is produced in the stomach. Food enters the large intestine before the small intestine. In the small intestine, chyme mixes with bile, which emulsifies fats. The stomach is separated from the small intestine by the pylloric sphincter.Watch this animation (http://openstaxcollege.org/l/stomach1) that depicts the structure of the stomach and how this structure functions in the initiation of protein digestion. This view of the stomach shows the characteristic rugae. What is the function of these rugae?
- which anatomical modification slows the movement of chyme through the small intestine? Microvilli, circular folds, villiOn the histological preparation of the walls of the small intestine: there * are groups of cells at the bottom of the crypt, in the apical part of which there are large acidophilic secretory granules; the cytoplasm is basophilic. What are these cells? goblet cells. Columnar cell with a border. O Endocrine cells. Cells without border. Paneth cells.Which of the following is characteristic of the large intestine? It: is longer than the small intestine has rugae contains microvilii exhibits external muscular bands called taenia coli
- can you help me the label of this small intestine modelHistology of the intestine 4 layers are mucosa, submucosa, muscularis, and serosa Describe the tissue types found in each 4 layers and discuss their functionsTo increase the absorptive efficiency of the small intestine, the surface area of the mucosa is increased by the presence of folds in the wall called ___, and projections of the cell membrane called ___. Group of answer choices rugae : lacteals villi : microvilli microvilli : lacteals lacteals : rugae
- Watch this animation (http://openstaxcollege.org/l/sintestine) that depicts the structure of the small intestine, and, in particular, the villi. Epithelial cells continue the digestion and absorption of nutrients and transport thesenutrients to the lymphatic and circulatory systems. In the small intestine, the products of food digestion are absorbed by different structures in the villi. Which structure absorbs and transports fats?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 ductHistology of Large Intestine Walls Label the mucosa and submucosa of the large intestine wall by clicking and dragging the labels to the correct location. Lumen Mucosa with mucous glands Muscularis (circular and longitudinal layers) Submucosa Serosa O Victor P. Eroschenko Prav 18 of 20 Next >
