Explanation The human body consists of pair lungs of lungs (left lung and right lung). The trachea (windpipe) branches off into the left and right lung to form bronchi. The bronchus again divides into a number of branches called bronchioles. The bronchioles branches off into tiny sacs called alveoli. The exchange of gases takes place in alveoli. The air enters the body through the nose. From nose air passes onto larynx and pharynx and then reaches trachea...
