This video is a continuous of part 1 where we are going to open the thorax cavity of the dog from the right side and dissect the right lung. • Make sure to watch the previous video where we dissected the left lung. • The respiratory system comprises of the nasal cavity, pharynx, larynx, trachea, bronchi and lungs. Thorax and pleural sacs also from parts of this system. • • The Lung • The essential organs of respiration are right and left and each occupies the greater part of the thoracic cavity. They are accurately adapted to the walls of the cavity. Each lung is soft, spongy and highly elastic. • Each lung presents for description two surfaces, two borders, a base and an apex. The costal surface is convex and lies against the lateral wall of the thorax, it presents impressions of the ribs. The mediastinal suiface is less extensive and molded on the mediastinum and its contents. It presents a little in front of its middle, an irregular depression -the hilus of the lung where the root of lung, enter or leave the organ. • The root of the lung is composed of the structures, which enter or leave the lung at the hilus on the mediastinal surface. These are (I) the bronchus; (2) the pulmonary artery: (3) the pulmonary veins; (4) the bronchial artery; (5) the pulmonary nerves and (6) the pulmonary lymph vessels. • Don't forget to subscribe, share and hit the bell to get notifications for the other related anatomical videos. • Visit our Facebook page: • / animalsanatomy • • Dr. Aiyan
