Veterinary Physiology-I (DVM): Course Outline PHYS-101

Veterinary Physiology is the branch of veterinary science that studies the normal biological functions and processes of animals. It focuses on understanding how various systems of the animal body—such as the circulatory, respiratory, nervous, digestive, r

Course Description

The course is describing the physiological anatomy and physiological mechanisms of homeostasis, feedback control, cardiovascular and circulatory system as well as respiratory system in domestic animals along with clinical correlations of selected problems in domestic animals.
