The alimentary canal is the long In human beings, the air is taken into the body from nostrils. Answer :- Respiration can be termed as gaseous exchange, basically two types of gases are exchanged such as Oxygen and Carbon dioxide. Again during the exhalation process, the lungs contracts that means volume of lungs decreases and it leads to expansion of diaphragm. (i) Absorption of digested food.

Friction on the lungs surface is reduced by? The respiratory system is responsible for the exchange of gases in the living organisms. In terms of function, the respiratory system has the following two parts: 1) Conducting part This is the part from the nostrils to the terminal bronchioles. Eachbronchioles divide into alveolar duct which enters the alveolar sac or alveoli.The alveoli are made up of non-ciliated squamous epithelium cells.It is surrounded by network of blood capillaries. 2)When air is taken in and let out,lungs always contain a residual volume of air so that there is sufficient time for oxygen to be absorbed and carbon dioxide to be released.
