How the Body Works: The Respiratory System
The network of air tubes spreading out just like the branches and twigs of a tree, form the structure of the lungs. The trachea, or windpipe, divides into two bronchi and these on entering the lungs, divide into bronchioles, alveolar ducts, alveolar sacs and individual alveoli. The right ventricle of the heart pumps deoxygenated blood to the lungs via the pulmonary arteries. At the alveoli, gaseous exchange of oxygen and carbon dioxide takes place between air in the lungs and blood in surrounding capillaries.

Movie to explain the Respiratory System (with questions) Lung Anatomy
This 3D medical animation begins with a detailed description of the anatomy and physiology of the lungs (Pulmonary system). It describes the pleura and diaphragm which aid in lung expansion. The animation also deals with lung cancer and the role of lymph in transporting bacteria, allergens and cancer cells away from the lungs and to the lymph nodes.
