Comparative pathology is a field of pathology that examines the pathology of disorders in living organisms, particularly those that are comparable to human pathology. It is a crucial component of veterinary and animal care. These investigations look at both human and animal fatalities. Just as the real-life frames of historical events exclusively dealt with man and the higher animals, the drug has recently rejected all of the frenzied miracles that occur in the lower animals. However, at that time, studying these animals is beneficial because their life conditions are more difficult than those of humans and vertebrates, not because they are more difficult.
