Physiology of growth, Climate Physiology and Behavioral Physiology. Animal physiology is a subject taught in the undergraduate and postgraduate courses in Colleges and Universities of Veterinary & Animal Sciences in India. With the advancement of knowledge, it has become difficult for majority of the students to go through various books for appearing in competitive exams quickly at a glance. Hence, an effort has been made to help students with a set of multiple choice questions based on the ICAR-NET/ARS/SRF syllabus covering the topics such as cellular basics of animal physiology, blood and circulation, respiration, excretion, digestion, muscle physiology, nervous system, endocrinology, reproduction, physiology of growth, climate physiology, and behavioral physiology.
