The way in which steroid and peptide hormones differ in their mechanisms of action. Introduction: The endocrine system is the chemical signaling system that uses blood vessels as information channels. The endocrine glands are ductless organs located within the organ systems and contain groups of endocrine cells that secrete their hormones directly into their surroundings. Hormones are signaling molecules that help to regulate physiology and behavior. The cells that are influenced by a particular hormone are known as target cells. They have specific binding receptors on the surface of the cell or within the cell. Hormones bind to these receptors to produce a characteristics response.

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
