Vital Organ Lungs. This animated widescreen PowerPoint template shows the human lungs breathing in and out while being measured by a spirometer. There is also a standard (4x3) version of this template available.
The lungs are the primary organs of respiration in humans and many other animals. Humans have two lungs, a right lung and a left lung. They are situated within the thoracic cavity of the chest. The right lung is bigger than the left lung, as the left lung shares space in the chest with the heart.The lungs together weigh approximately 1.3 kilograms (2.9 lb), with the right lung weighing more than the left.The lungs are part of the lower respiratory tract that begins at the trachea and branches into the bronchi and bronchioles and which receive air breathed in via the conducting zone.he lobes are further divided into bronchopulmonary segments and lobules. The tissues of the lungs have a unique blood supply, receiving deoxygenated blood sent from the heart for the purposes of receiving oxygen (the pulmonary circulation) and a separate blood supply of oxygenated blood (the bronchial circulation).
