| lumen |
In physics, specifically photometry (optics), the lumen (symbol: lm) is the SI derived unit of luminous flux. It is the amount of light that falls on a unit spherical area at unit distance from a source of one candela. In steradians this is equivalent to the amount of light that falls on a unit solid angle from a light source of one candela. Alternatively, one lumen is the total light produced by an isotropic light source of (1/4π) candelas. ...

| lung |
The lung is an organ belonging to the respiratory system and interfacing to the circulatory system of air-breathing vertebrates. Its function is to exchange oxygen from air with carbon dioxide from blood. The process in which this happens is called "external respiration" or breathing. The mechanism by which lungs enable respiration is called diffusion. There are also nonrespiratory functions of the lungs. ...
