Veterinary Physiology-II (PHYS-202): Course Outline (PHYS-202)

The course is describing the physiological anatomy and physiological mechanisms of digestive system, lactation, endocrine system, as well as renal system in domestic animals along with clinical correlations of common problems in domestic animals.

Course Introduction

Veterinary Physiology-II is a continuation of Physiology-I that focuses on the fundamental concepts of domestic animal organ systems like the nervous, endocrine, reproductive, respiratory, and circulatory systems. The course integrates knowledge of these systems to explain how an animal maintains whole-body homeostasis and includes topics such as metabolism, cellular communication, and the comparative physiology of different species. It also often includes the introduction to disease pathophysiology, preparing students for clinical subjects.
