Scientists and their Contributions
Human Disease and Prevention:
Diseases can be simply defined as a disruption in the normal functioning of the body, among which few affect only the particular organ system and some affect the whole body of an organism. Numerous diseases vary in their signs, symptoms, and causes. Pathology is the branch of medicine that mainly deals with the study of disease, the nature of diseases, its cure, diagnosis, etc.
Human Physiology
Diet and Balanced diet
Human Genetics:
Genetics is the science that deals with the mechanisms liable for similarities and differences among closely related species. The word ‘genetic’ was coined by W.Batesmanin in 1905. It is emanated from the Greek word ‘genesis’ indicating grow into or to become. So, genetic is the study of heredity and hereditary variations it is the study of the transmission of body features: ie, similarities and difference, from parents to offspring and the laws associated with this transmission.
