Body Organs: Lung, Esophagus, Spleen Functions Defined

Lung: The lung is responsible for implementing the respiration or the breathing system of our body. Through respiration, air from the atmosphere is taken inside our body to the pair of lungs, where the oxygen in the air is extracted and carbon dioxide in the blood returned to the air. The blood is thus refreshed and recharged everytime we breathe in. The exchange of gases happens due to the presence of arrays of very thinly walled air sacs, across the lung wall called alveoli.


Esophagus: The Esophagus is the part of our body which basically is responsible for passing the

chewed food from our mouth to the stomach for the further process

of digestion.
It can be identified as a muscular, tubular organ connecting the mouth through the pharynx to the stomach.
The ingestion takes place from the mouth, to the pharynx, then into the esophagus and finally passes through the peristalsis into the stomach.
