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.

NIH launches "Knockout Mouse Project"

Disabling carbohydrate trigger reduces obesity and appetite

Until about 15 years ago, insulin was believed primarily responsible for turning carbohydrates into fat. But then it became apparent that diet alone could stimulate glucose metabolism and fat synthesis, even when insulin levels were low or absent.

How kidneys retain proteins, discard waste

New research may finally settle a decades-old debate about how the kidney keeps valuable blood proteins from harmfully slipping into the urine, a serious health symptom that often precedes kidney failure.

Celiac success: New enzyme efficiently degrades gluten

A new enzyme originally developed for commercial food processing turns out to also quickly and nearly-completely break down whole gluten molecules as well as the T cell stimulatory peptides that cause celiac disease, a digestive disease with no current effective treatment other than avoiding wheat, barley or rye products.
