why are villi present in the intestine and not in the stomach????

viilis are present in intestine to maximize the contact area to food to extract things like water,etc

while they are not present in stomach because here food is to be glazed with digestive enzymes and juices.

The major portion of absorption takes place in small intestines. In stomachsimple sugars, water and alcohol are absorbed. Villi are specialized projections insmall intestine with large absorbent area. This facilitates better absorption ofcompelx molecules as well. As food is fit to be absorbed only after completedigestion so villi’s turn come after all the digestive processes are complete.

in stomach simple sugars , water and alcohol are absorbed. but it is not possible to absorb other elements as they are in complex state from stomach to small intestine the digestion process is almost completed and the complex food molecules are converted into simpler form and are ready to be absorbed. this is why it helps villi to absorb all the efficient thing present there which were not absorbed in stomach. so if villi were present in stomach most of efficient things could not have been absorbed.

hope it helps you :)

villi has to absorb the food and send it to blood which will send digested food to all cells

in stomach food is not completely digested  but in small intestine the food is completely digested , thats y villi are present in small intestine coz they want to absorb completely digested food so cells can use it to generate energy
