Hormones are chemical messengers secreted by glands into the extracellular fluids. The secreted hormones reach the target cells through the bloodstream and they stimulate response of other tissues or cells. Hormones bind only to specific cells based on their corresponding receptors on cells and they act through chemical signals. They regulate growth, development, blood pressure, metabolism , fluid concentration, and maintain homeostasis in the body. Both the positive and negative feedback mechanism may regulate hormone pathways. Positive feedback amplifies the stimulus whereas; negative feedback dampens the stimulus and stops the pathway.

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
