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 study sheds light on irregular heartbeat risk

Two new, basic animal research studies shed light on alcohol consumption and the heart. The first study may help explain why binge drinking sometimes causes an irregular heartbeat and a possible way to prevent it. The second study investigated why alcohol may have a negative impact on heart function in women taking estrogen replacement therapy.
