Question

Which part of the digestive system helps in
A) detecting taste b) killing the bacteria c (absorption of food d) movement of food from buccal cavity to stomach.

Answer 1

Answer:

A) Most of the taste gets detected in the front part of the tongue because most of the taste buds are present in the front region of the tongue.

B) Enzymes in saliva kill some bacteria and protect the mouth from infection. When food reaches the stomach, much of it is sterilized by the hydrochloric acid in digestive juices. Further into the digestive tract, the friendly bacteria living in the intestines provide protection from invading bacteria.

C) What happens to the digested food? The small intestine absorbs most of the nutrients in your food, and your circulatory system passes them on to other parts of your body to store or use. Special cells help absorbed nutrients cross the intestinal lining into your bloodstream.

D) The esophagus is a tubular organ connecting the mouth to the stomach. The chewed and softened food passes through the esophagus after being swallowed. The smooth muscles of the esophagus undergo a series of wave like movements called peristalsis that push the food toward the stomach.
