Discuss the roles of vitamin A in body functions other than the vision
Vitamin A has many important functions beyond vision. Vitamin A plays an important role in cell differentiation, the process by which a nonspecialized, immature cell type becomes a specialized, mature cell type. Vitamin A is also critical for growth and reproduction, and it has a variety of immunological functions. These include the maintenance of protective barriers (such as skin and those that line organs) and the production of immune cells (such as those that produce antibodies). Preformed vitamin A is also essential for healthy bones.
