Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.

Differences in mitochondrial DNA determine severity of heart disease caused by nDNA mutation

Natural plant compound exploits newly identified Achilles' heel in uveal melanoma

A natural plant compound exploits a newly identified Achilles' heel in a cancer of the eye, uveal melanoma. In human cancer cells growing in the lab, the compound shuts down the overactive signaling that drives uveal melanoma cell growth, according to researchers at Washington University School of Medicine in St. Louis.
