First published in the late 20th century, Berry’s Animal Physiology (often referred to as the “green-covered” or “orange-covered” edition depending on reprint) has served as a standard reference for B.Sc. students.

This paper evaluates its chapters on nerve-muscle physiology, circulation, respiration, excretion, endocrinology, and reproduction. animal physiology by ak berry pdf
