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.
Muscle regeneration takes place through a complex mechanism that involves different steps and relies on stem cells.
A University of Alberta-led study shows that when it comes to susceptibility to infections and other health conditions, sex matters.
Human DNA has a close resemblance to that of the chimpanzee, which in evolutionary terms is the closest living relative of humans.
Multi-institutional researchers have succeeded in efficiently delivering an immune checkpoint inhibitor (ICI) into the mouse brain, confirming its high efficacy and specificity in treating orthotopically transplanted mice with glioblastoma (GBM). The research was published in Nature Biomedical Engineering.
Daily cycles in virtually every aspect of our physiology are driven by biological clocks (also called circadian clocks) in our cells.
Mature oak trees will increase their rate of photosynthesis by up to a third in response to the raised CO2 levels expected to be the world average by about 2050, new research shows.
New research published in The Journal of Physiology has shown that ketone supplements may be a novel therapeutic strategy for protecting and improving brain health in people with obesity.
Scientists from the University of Illinois Urbana-Champaign isolated and chemically characterized individual organelles within cells swiftly.
Almost every living thing on Earth-;from bacteria to plants to people-;have a circadian rhythm, the biological clock that controls both physiology and behavior of organisms over a 24-hour period.
Scientists from the Karolinska Institutet pinpointed a protein that enhances motor coordination, muscular metabolism, and exercise performance in mice.
Scientists from Weill Cornell Medicine recently found the master regulator behind the development of antibody-creating cells.
A naturally occurring protein that blocks an inflammatory immune response was associated with better stroke recovery in a study conducted in mice, according to preliminary research to be presented at the American Heart Association's Vascular Discovery: From Genes to Medicine Scientific Sessions 2021.
In human cancer cell and mouse studies, researchers from Johns Hopkins Medicine have found that a set of proteins work in tandem to build supply lines that deliver oxygen and nutrients to tumors, enabling them to survive and grow.
The National Science Foundation has announced the award of $12.5 million to Arizona State University for the development of a new Biological Integration Institute.
Fish can drown. While it may not seem like it, fish do require oxygen to breathe; it's just that they get what they need from the oxygen dissolved in water rather than in the air.
Ginseng, a widely popular superfood, has long been used in traditional medicine. The health benefits of ginseng are largely attributed to compounds called ginsenosides, which are present in the roots, stems, and leaves of the plant. Ginsenosides are known to prevent inflammation, diabetes, and cancer, and can also help control blood cholesterol levels and reduce aging.
Researchers at Kobe University's Biosignal Research Center have successfully developed plants that can be used to detect organic pollutants, such as polychlorinated biphenyls and endocrine-disrupting chemicals, which contaminate soil and water.
Sesame is one of the most versatile crops. Sesame seeds are a reservoir of healthy fats and protein. The oil extracted from sesame seeds is a premium cooking oil.
Getting your day started sometimes feels like it requires magic, but making a good cup of tea requires a little science.
When rats are fed a high fat diet, this disturbs the body clock in their brain that normally controls satiety, leading to over-eating and obesity. That's according to new research published in The Journal of Physiology.
