The left lung has an indentation, called the cardiac depression, for the normal placement of the heart. Behind this is the hilum, through which the blood vessels, lymphatics, and bronchi enter and leave the lung.Air travels from the nasal passages to the pharynx, larynx, and trachea.hat part of the lung that is not covered by pleura and through which blood vessels, bronchi, nerves and lymphatics enter and leave the lung. lung lobe torsion. occurs uncommonly in dogs and cats, most often of the right middle lobe. May occur spontaneously, following trauma, or in association with pleural effusion.
The Carbon Dioxide is not absorbed into the blood it is only the oxygen. When you breathe in, the air travels down your windpipe, down the bronchi and then down the bronchis.â¦ On the end of the bronchioles, there are sacs called alveoli.he gaseous exchange of oxygen (O2) and carbon dioxide (CO2) occurs within the lungs. Oxygen is inhaled through the mouth and nose, it passes through the bronchi, which branch â¦ off into smaller airways called bronchioles.
