Chemical Digestion in the small intestine video
Chemical digestion in the small intestine, video course for free, online chemical digestion and small intestine, then large intestine digestion and absorbing water process.
absorbtion
There are four essential aspects to absorbtion:
1) physical movement of the nutrient molecules from gut lumen to the wall of the gut tube.
2) maximizing the area of the epithelial cells across which absorbtion can occur.
3) mechanism for transport of the nutrient molecule across the cell membrane into the epithelial cell cytoplasm.
4) transport of the nutrient molecule out of the epitheali cell into the extracellular body fluids. The mammalian small intestine is highly specialized for digestion and especially absorbtion . The mammalian small intestine is higly specialized for digestion and especially aabsorbtion.
Villi and microvilli increases absorbtive surface of small intestine. Each villus containt of lacteal, which is a terminal branch of the lymphatic system and is a terminal branch of the lymphatic system and is an important route for reabsorbtion of lipids and water. The surface of microvilli is covered with a meshwork of mucopolysaccharide and glycoprotein filaments, the glycocalyx.
This surface coat is extremely resistant to proteolytic and mucolytic agents, hence forms a protective surface.
glucostatic
Hunger drive is controlled by hypothalamus. Glucostatic thery of hunger suggests that an increase in blood glucose level increases the activity of the safety center and decreases the activity of hunger center. Low blood glucose has the opposite effects. Aminoacid levels and lipid levels have also been suggested to influence hunger and satiety. The hepotostatic theory of hunger control argues for a role of liver as an important sensor and modulator of the body energy stores. digestion
Digestive system in mammals
General anatomy of digestive system. Ozofagus 1/3 is striated muscle, 2/3 is smooth muscle. Small intestine: duodenum, jejenum, ileum. The end of ileum is appendix (secum in horse) in human. Large intestine: colon, rectum, anus. the structure of digestive tract. Muscularis mucosa, mucus layer, submucosa. Plexus myentericus. In the large intestine, longitiudial muscles concentrated circular muscle n large intestine produce haustra formation. The length of digestive tract depends on type of food ingested by animals. Longest in herbivours, shorter in carnivores.

The Slow Food Movement’s Health Impact
The slow food movement is said to have originated with Italian Carlo Perrini, in part through his indignation at a McDonald’s opening in the vicinity of the Spanish Steps in Rome. From Perrrinis’ frustration with the intrusion of the American fast-food style of dining a worldwide movement has emerged. The hallmark of slow food is, as its name implies, taking the time to savor and enjoy a meal at a leisurely pace. Other elements of the slow food diet include buying and eating locally produced food, eating organic food and cooking home meals based on traditional recipes.
The slow food movement has certainly caught on, due in part to people being tired of the fast-food dining style and also out of a passion to eat healthier food. But does the slow food movement make for better health? The general outlook of the slow food movement on changing the eating habits of people does seem to assure that eating meals the slow food way will have a positive impact on your life. One major health benefit of the slow food is eating your meals slowly. Most research on the topic indicates that eating at an unhurried pace will help you promote a calm that in turn helps aid digestion.
Another health benefit of the slow food movement is its interest in getting people to buy locally grown fresh foods with minimal packaging and processing. Again, these are all ways of approaching eating that contribute to a more healthy lifestyle by reduced the amount of fat, preservatives and other chemical additives in your food. In addition, the slow food movement encourages people to buy organic produce as much as possible, thereby greatly reducing or eliminating the amount of pesticides in your diet. It seems clear that the slow food movement is designed to make you eat healthier and live a healthier lifestyle. by digestive phsiology
