Air mass is a large body of air that exhibits uniform temperature and moisture characteristics and helps to determine the weather within an area. Warm air masses tend to form over oceans in warm-temperature regions of the tropics and sub-tropics, while cold air masses tend to form over land in cold-weather regions nearer the poles. The cold air masses that form at the poles move toward the equator, while the warm air masses that form at the equator move toward the poles. These air masses can undergo gradual, but significant, changes as they pass over warmer or colder land surfaces encountering different types of air. These boundary lines are called front.

The term used for the condition, in which the uptake of nutrients from the small intestine is impaired is malabsorption.
The malabsorption is a condition, in which the small intestine walls become unable to uptake the nutrients in the blood. This condition can be caused by many different reasons, which affect the wall of the intestine. These conditions include infections, trauma, celiac disease, and surgery. Some diseases such as Crohn's disease, pancreatitis (chronic), or cystic fibrosis is also responsible for the malabsorption.
