In this video, I describe every part of the thoracic region that's included in the anatomical torso model. Mammary glands, lactiferous ducts, areola, pectoralis major, sternum, costal cartilage, ribs, intercostal muscles, lungs, trachea, bronchi, heart, atria, ventricles, coronary arteries, auricles, esophagus, thoracic duct (and connection to the subclavian vein), veins (azygos, hemiazygos, accessory hemiazygos), and nerves of the mediastinum.

‼️ CORRECTIONS:
1) There are 5 total false ribs, 2 of which are floating. I mentioned 3 of the false ribs, then the 2 floating ribs, without clarifying that the floating ribs are also considered false ribs.
2) What I labeled the "accessory azygos vein" is actually called the "accessory hemiazygos vein."
