The reason for considerable controversy about the level of dietary vitamin D intake that should be recommended. Introduction: The integumentary system of body mainly comprised of skin and its components like hair, scale feathers, and so on. The skin is the outer covering of body and it has important role in protection of body from external environment. The skin also helps in the regulation of body temperature. The skin manufactures precursor molecule that is converted into “vitamin D after exposure to UV light (from sun)”. The body requires vitamin D for the absorption of calcium to promote the bone growth and development.

Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration. Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpo
