Definition

Noun: 1. A respiratory organ: One of a pair of large, spongy, saclike organs located in the chest cavity of most vertebrates. Their primary function is to exchange gases: they remove carbon dioxide from the blood and provide it with oxygen from the inhaled air.

Examples of Usage

• Noun:

Advanced Usage
