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.

New research illustrates how fear arises in the brain

An estimated 8% of Americans will suffer from post traumatic stress disorder (PTSD) at some point during their lifetime. Brought on by an overwhelming or stressful event or events, PTSD is the result of altered chemistry and physiology of the brain.

Blocking bacteria's access to iron: an interview with Dr. Laxminarayana Devireddy

Iron is a key nutrient for nearly all living organisms, including bacteria. Iron is a cofactor for many enzymes necessary for basic metabolic reactions such as DNA synthesis and electron transport. Iron serves as the conduit for the electron transport chain that generates the energy necessary to drive the bacterial cell.
