An infant (from the Latin word infans, meaning unable to speak or speechless) is the very young offspring of a human or other animal. When applied to humans, the term is usually considered synonymous with baby or bairn (in Scottish English), but the latter is commonly applied to the young of any animal.
The Function of Vitamin K. Vitamin K refers to a group of vitamins which includes vitamin K1 and vitamin K2. Vitamin K1 is synthesized by plants. Vitamin K2 is mainly produced by both humans and animals, but also by bacteria found in the large intestine.
Vitamin K1 can be converted to its storage form, Vitamin K2, by bacteria in the large intestine. Vitamins K3-5 are synthetic and can be purchased as supplements. Vitamin K plays a major role in blood clotting, bone metabolism and the regulation of blood calcium levels. It is absorbed in the small intestine and stored in fatty tissue and the liver. Vitamin K is utilized by the liver in the production of prothrombin (clotting factor).
