How are lipids digested in the mouth
The salivary glands secrete digestive juices containing enzymes that break down the food chemically into smaller, more absorbable molecules.An enzyme in the saliva called amylase begins the breakdown of carbohydrates into simple sugars, such as maltose.

- How do lipids move through the body so they can be digested and a…?
- In order for lipids to move through the bloodstream they must combine with proteins to form lipoproteins. liquids are spelt liquids not lipids Lipids is correct. The question is not liquids. Also, it is spelled not spelt!
- What happens to the absorbed lipids?
- It is packaged (surrounded by protein and phospholipid to make it soluble) and is then secreted into lymph as chylomicrons where they follow the lymphatic tracts to the thoracic duct and left subclavian vein. The fatty acids are taken up fr…

- A: Carbohydrates: The digestible carbohydrates are broken into simpler molecules by enzymes in the saliva, in juice produced by the pancreas, and in the lining of the small intestine. Starch is digested in two steps: First, an enzyme in the saliva and pancreatic juice breaks the starch into molecules called maltose; then an enzyme in the lining of the small intestine (maltase) splits the maltose into glucose molecules that can be absorbed into the blood. Glucose is carried through the bloodstream to the liver, where it is stored or used to provide energy for the work of the body.Table sugar is another carbohydrate that must be digested to be useful. An enzyme in the lining of the small intestine digests table sugar into glucose and fructose, each of which can be absorbed from the intestinal cavity into the blood. Milk contains yet another type of sugar, lactose, which is changed into absorbable molecules by an enzyme called lactase, also found in the intestinal lining.Protein: Foods such as meat, eggs, and beans consist of large molecules of protein that must be digested by enzymes before they can be used to build and repair body tissues. An enzyme in the juice of the stomach starts the digestion of swallowed protein. Further digestion of the protein is completed in the small intestine. Here, several enzymes from the pancreatic juice and the lining of the intestine carry out the breakdown of huge protein molecules into small molecules called amino acids. These small molecules can be absorbed from the hollow of the small intestine into the blood and then be carried to all parts of the body to build the walls and other parts of cells.Fats(Lipids): Fat molecules are a rich source of energy for the body. The first step in digestion of a fat is to dissolve it into the watery content of the intestinal cavity. The bile acids produced by the liver act as natural detergents to dissolve fat in water and allow the enzymes to break the large fat molecules into smaller molecules, some of which are fatty acids and cholesterol. The bile acids combine with the fatty acids and cholesterol and help these molecules to move into the cells of the mucosa. In these cells the small molecules are formed back into large molecules, most of which pass into vessels (called lymphatics) near the intestine. These small vessels carry the reformed fat to the veins of the chest, and the blood carries the fat to storage depots in different parts of the body.
- anatomy questions true or false?
- Q: 1.) fats significantly delay the emptying of the stomach2.) mumps is an inflamation of the parotid glands caused by mycovirus.3. most nutrients are absorbed through the mucosa of the intestinal ville by active transport?4.) another term for swallowing is deglutination5.) the function of the enzyme amylase is to begin digesting proteins?6.) chemical digestion of lipids is initiated in the mouth?7.) the main chemical activity of the stomach is to begin the digestion of proteins?8.)pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells.9.) the pharangeal -esophogeal phase of swallowing is involuntary and is controlled by the swallowing center in the thalamus and lower pons.10.) some of the microbes that often invade other organs of the body are rarely found in the stomach. the reason for this is the presence of HCL.thank you guys!!!!
