Answers
absorption ( b) is not a function of stomach
Answer:
The stomach has the capability of performing all the functions in the list except for completion of digestion of fats. The stomach does not complete the digestion of fat.
Explanation:
Digestion of fats begin in the mouth where they are acted upon by the enzyme known as lingual lipase. Digestion of fats is then completed in the small intestines by use of lipases present in the illeum.
Functions of the stomach:
1) Absorption - nearly 90% of all digested food is absorbed in the illeum ( the small intestines). The stomach on the other hand is capable of absorbing certain lipid-soluble compounds like ethanol and drugs like aspirin.
2) Digestion - the stomach takes part in both mechanical and chemical digestion of ingested food. The stomach produces hydrochloric acid and proteases that digest proteins and breakdown food. The stomach is a muscular organ that breaks down food mechanically by churning food through peristalisis.
3) Storage - the stomach is capable of storing about 1 liter of food. The food can be stored for upto 6 hours as it undergoes digestion.
