- Lipid absorption involves hydrolysis of dietary fat in the lumen of the intestine followed by the uptake of hydrolyzed products by enterocytes. True FalseExplain the details of vitamin B12 absorptionThe neural and hormonal control of the digestive system is divisible into three phases. Discuss the gastric phase of the regulation which produces more than 50% of gastric acid.
- On the histologic section of the glands stomach's fundus, relatively large electron-microscopically cells with acidophilic cytoplasm can be seen, and in these cells there is a complicated system of intracellular tubules. What component of gastric juice is formed due to the activity of these cells? Serotonin Mucus Gastrin O Hydrochloric acid OpepsinogenIn which part of alimentariy canal does absorption of water, simple sugars andalcohol lakes place?All the structures of the alimentary canal have 4 similar major histological tissues . Which of the following descriptions of the tissue layers contains innacurate information? A) The mucosa layer consits of a simple epithelium (responsible for absoprtion), a lamina proprioa (supports the epithelium) and muscularis mucosae (thats ivolved with peristalsis. B) The muscularis externa has 2 or 3 layers of smooth msulce and is involced with persistalsis C) The submucosa layer is a connective tissue layer that anchors the mucosa layer and contains many blood vessels, lyphatic vessels, and nerves D) The serosa layer is a connective tissue layer that tethers the alimnetary canal to the appropirate body cavitities. I believe that D is false but I am not certain
- The wall of alimentary canal is made up of four layers. Give the names of these four layers.Water Absorption During Digestion While both the small and large intestines absorb water, they do not share the job equally. Consider the following typical measurements: Volume entering the small intestine: 9,400 mL Volume entering the large intestine: 750 mL Volume leaving the large intestine: 300 mL What percentage of the water entering the small intestine is absorbed by the small intestine? What percentage of the water entering the small intestine is absorbed by the large intestine? What percentage of the water entering the small intestine is not absorbed during the digestive process?In the duodenum lipid stimulate cck secretion. Explain how this would affect gastric emptying, pancreatic function, gallbladder secretion, and the sensation of hunger.
