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.
Female kidney donors who are overweight may be at a greater risk for preeclampsia during pregnancy, according to a new study.
For the first time, researchers have described atom-by-atom changes in a family of proteins linked to amyotrophic lateral sclerosis (ALS), a group of brain disorders known as frontotemporal dementia and degenerative diseases of muscle and bone.
Gender-based differences may influence several ocular conditions, suggesting that fluctuations in sex steroid homeostasis may have direct effects on eye physiology and the pathogenesis of conditions like Age-Related Macular Degeneration.

Guang Yue, PhD, director of Human Performance and Engineering Research at Kessler Foundation, has been awarded a $735,000 grant from the National Institute on Disability, Independent Living, and Rehabilitation Research.
Scientists at Université de Montréal have developed a unique technique to map, on a scale of milliseconds, the elasticity of the components inside a cell.
Scientists have discovered a new enzyme in adipose tissue that helps regulate inflammation. The discovery could help in the battle against obesity.
The fat of obese people becomes distressed, scarred and inflamed, which can make weight loss more difficult, research at the University of Exeter has found.
The failure of drugs such as SSRIs, used to treat depression, can be a result of genetic variations in patients.
Scientists at the Centro Nacional de Investigaciones Cardiovasculares Carlos III and Columbia University in New York have discovered an important mechanism in the regulation of a protein that plays an essential role in the function of skeletal muscle and the heart.
Mutated RAS genes are some of the most common genetic drivers of cancer, especially in aggressive cancers like pancreatic and lung cancer, but no medicines that target RAS are available despite decades of effort.
Elevated levels of the inflammation marker CRP in the blood is an underlying cause of the loss of muscle mass in elderly persons, as shown by a new study from örebro University and University of Nottingham.
The human body has two primary kinds of fat--white fat, which stores excess calories and is associated with obesity, and brown fat, which burns calories in order to produce heat and has garnered interest as a potential means of combating obesity.
A new study reports that chronic exposure to arsenic interferes with insulin secretion in the pancreas, which may increase the risk of diabetes.
Astronauts float weightlessly through space, and the condition of weightlessness is something many would love to experience.
According to a recent study published in The Journal of Physiology, researchers have been able to document for the first time how the same period of inactivity has a greater and more severe impact on the muscle power of the lower limbs of the elderly than young people, which is essential for movements like climbing the stairs.
The National Institutes of Health has awarded Wake Forest Baptist Medical Center a grant worth an estimated $8 million over five years for the establishment of a new center for research into alcohol addiction.
