Peristalsis starts at the esophagus and ends with defecation. Which of these equations would best be associated with a digestive enzyme? Digestion involves the breaking of chemical bonds. All of these are ways your body detects the presence of food and, as a result, prepares itself for the intake of food.
Halitosis may be a indication of serious health issues such as diabetes. This is not quite as acidic as the HCl secreted by the stomach. What name is given to a unit of swallowed food? The tongue shapes chewed and partially digested food into a bolus that is then swallowed. This is why a lack of stomach acidity increases the risk of certain nutrient deficiencies. In addition, stomach acidity can kill pathogenic bacteria that may enter our bodies along with food and drink.
Emulsification occurs when large fat globules are broken up not digested into smaller fat globules. More, smaller fat globules increase the surface area available for the fats and faciltates digestion.
Bile is also required for fat to be absorbed. Vili increases the surface area of the small intestine. This allows for the presence of more of the digestive enzymes that are attached to the surface of intestinal cells and also increases the surface area available for the absorption of nutrients.
One possible reason for this linkage is that straining to defecate raises blood pressure and increaased blood pressure increases cardiovascular risk. Most kidney stones are composed of calcium oxalate. Calcium and iron compete to be absorbed by the small intestine. However, there is evidence that over the long term, calcium supplementation may not lead to an iron deficiency. Vitamin D promotes the absorption of both calcium and phosphorus. Under the influence of vitamin D, the kidneys promote the reabsorption of calcium and phosphorus, keeping these minerals in the body.
Periodontal disease refers to diseases that have a direct impact on the structures that are responsible for keeping the teeth in place. What are the major causes of peptic ulcers? There are three types of peptic ulcers: Esophageal ulcers are caused by the damage done to the esophagus as a result of the chronic reflux of stomach content GERD s.
Anything that disrupts the mechanisms that protect the lining of the stomach or small intestines from the action of acids and enzymes may lead to the formation of an ulcer.
Disruption of these protective mechanisms can be caused by infection with H. NSAIDs non-steroidal anti-inflammatory drugs, include aspirin and ibuprofen. The mechanisms by which NSAIDs reduce inflammation is the same mechanism the disrupts an aspect of the mechanisms that protect the lining of the GI tract from acid-induced damage.

Which one of the following is stated incorrectly? Manufactures bile, converts the amino groups to urea. Makes all the cholesterol that human body needs. Which one of the following statement is not correct about intestinal villi? A multitudinous finger-like projections having many microvilli. Increase the internal surface area of the intestinal wall.
Supplied with capillaries and the lacteal vessels. The following list describes four major digestive enzymes. Which one of the following is incorrect? Which one of the following is the correct matching of the site of action on the given substrate, the enzyme acting upon it and the end product? If for some reason our goblet cells are non-functional this will adversely affect.
Secretion of sebum from the sebaceous glands. What will happen if the secretion of parietal cells of gastric glands is blocked with an inhibitor? Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin. Gastric juice will be deficient in pepsinogen. In the absence of HCl secretion, inactive pepsinogen is not converted into the active enzyme pepsin. A young infant may be feeding entirely on mother's milk which is white in colour but the stool which the infant passes out is quite yellowish.
What is this yellow colour due to. Name the hormone that stimulates the secretion of gastric juice. Bile salts act as activator of which enzyme?
