Why is the pH of stomach acid low?
Low pH is needed to start the denaturation and digestion of proteins, which occurs in the stomach.
What important roles stomach perform during digestion?
The stomach secretes these fluids:•Gastric juice: acidic liquid secreted from the stomach; it contains hydrochloric acid, pepsin, water, and other compounds•Hydrochloric acid: very acidic, starts to denature proteins, converts pepsinogen into active enzyme pepsin (assist in protein digestion), kills many bacteria and germs that may have entered the body•Pepsin: proteins and fats enter the stomach largely unchanged, begins digestion of protein and activates other GI enzymes needed to digest your meal•Gastric lipase: one enzyme responsible for fat digestion, not very much produced so little digestion occurs•Mucus: thick whit fluid that protects the stomach lining from being digested by HCl and pepsin•the stomach also mixes and churns (more mechanical digestion) food until it becomes liquid chyme•Stomach has three bands of muscles; longitudinal, circular and diagonal•Pyloric sphincter regulates the release of chyme from the stomach into the first part of the small intestine, the duodenum
Which organs produce the enzyme lipase needed for triglyceride digestion?
salivary amylase.
What 3 organs help the small intestine during digestion?
GALBLADDER and PANCREAS
Why is acid needed in the stomach?
The stomach is acidic in order to kill any bacteria that enter the stomach. The acid does not break down food, but contains an enzyme called protease, a form of pepsin, which breaks down proteins into polypeptide chains. No further digestion takes place in the stomach, as this takes place in the ileum, small intestine. The stomach has to maintain its acidity for the enzyme protease to function. The stomach acid is very acidic, but is also quite dilute, and the acid (Hydrochloric Acid) is fairly harmless in this diluted state.
Which cranial nerve is involved when disgesting?
The cranial nerve X (Vagus Nerve) is involved for digestion. It stimulates the stomach and releases gastric juices including water, pepsin and hydrochloric acid which is needed for digestion.
What is the approximate pH of gastric juice that will ensure proper digestion?
stomach acid works at an optimum level of 2.4. the reason of this is because the pepsinogen in the stomach cavity will not be properly activated into pepsin unless the level of H+ concentration is substantially high. pepsin is needed for protein digestion.
What is needed to digest proteins?
Mainly, the enzyme Protease breaks up proteins into amino-acids. Also, proteins contain nitrogen which the body cannot use. Water is required to remove this nitrogen, bonding with if to form ammonia. This is subsequently secreted in urine.
What is meant by acidity in stomach and how can it be cured?
Various stomach acids are needed to breakdown our food and aid digestion. Excess acid (heartburn) is cured by using anti-acid tablets or liquid medicines.
How would removal of 95 percent of the stomach to treat severe ulcers or cancer affect the digestion and absorption of food?
The stomach stores food and released small amounts regularly into the intestines for digestion. If the stomach was removed the patient must eat small amounts of food regularly. If they ate a normal sized meal it passes into the intestine and due to osmosis, a great deal of water moves into the intestines - 'dumping syndrome' which can cause nausea, diarrhoea, bloating, cramps, fatigue and dizziness. It would also affect blood sugar and could cause hypoglycaemia. So removal of the stomach makes digestion and absorption much more difficult.The stomach lining cells also produce Intrinsic factor which is needed for the absorption of vitamin K. Therefore the patient may become deficient in vitamin K.The job of the stomach is to break down proteins, mix and begin digestion. It is not involved in the absorption of food. If a person has a small stomach, they will loose weight but the stomach can stretch and enlarge.
Chewing and churning are examples of what type of digestion?
Chewing is a mechanic digestion as i found out here on WikiAnswers. So i hope i have answered you question those of you who have needed this little bit of information x.what the heck are u talking about?
What is the Hormone that regulates pH of stomach?
Acid (Hcl) is secreted by the parietal cells of the stomach. In the stomach the food itself and saliva from mouth (this is little alkaline) regulates acidity of the stomach. But acid in normal quantity is needed for digestion, specially for meats, hard and solid foods.
