The developing lung is particularly vulnerable to changes in the levels of vitamin A. Vitamin A deficiency has been linked to changes in the epithelial lining of the lung and in the lung parenchyma.
The lungs are the main part of your respiratory system. Here is how lungs work as the center of your breathing, the path a full breath takes in your body, and a 3-D model of lung anatomy.
Lung, in air-breathing vertebrates, either of the two large organs of respiration located in the chest cavity and responsible for adding oxygen to and removing carbon dioxide from the blood.
A typical adult lung weighs about 2.2 pounds (1 kilogram) and is a little longer than 9 inches (about 24 centimeters) when you’re breathing normally. It’s about 10.5 inches (27 cm) when your lungs are completely expanded.
Each soft, spongy lung is roughly cone-shaped with the superior end of the lung forming the point of the cone and the inferior end forming the base. The superior end of the lungs narrows to a rounded tip known as the apex.
