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.

Eating potatoes provides as much fuel as carbohydrate gels for athletes

Eating a potato during exercise provides as much fuel and results in similar performance in trained athletes as carbohydrate gels.

Flinders University study provides new insights into how the colon functions

New insights into how the colon functions and actually expels its contents have been revealed for the first time following decades of study by Flinders University researchers.

Scientists solve first structure of human cotransporter protein KCC1

In work that could someday improve treatments for epilepsy, UT Southwestern scientists have published the first three-dimensional structure of a member of a large family of human proteins that carry charged particles – ions – across the cell membrane.

NSU study points to another potential connection between sleep and overall good health

As if you didn't already have enough to worry about to keep you up at night, a new study indicates that poor sleep can negatively affect your gut microbiome, which can, in turn, lead to additional health issues.

Study confirms differences in dominant- versus non-dominant-leg power output during exercise

A new study confirms important differences in dominant- versus non-dominant-leg oxygen usage and power output during single-leg exercise.

Researchers discover new chemical weapon to fight against cancer

The fight against cancer involves eradicating cancer cells but current treatments inevitably have negative consequences on healthy cells.

New approach to treating high blood pressure

The key to treating blood pressure might lie in people who are “resistant” to developing high blood pressure even when they eat high salt diets, shows new research published in Experimental Physiology.

High glucose impairs circadian clock function, may increase cardiovascular risk

High glucose in obesity appears to gum up the works of the circadian clocks inside our cells that help regulate the timing of many body functions across the 24-hour day and drive the risk of cardiovascular disease, scientists say.

Performance-enhancing with ... potatoes!

Athletes who are training need to go through grueling endurance tests. One proven strategy to boost their performance during such tests is to eat carbohydrates as race fuels. Now, an interesting study published on October 20, 2019, in the Journal of Applied Physiology reports that athletes in training could get their energy just as well from a mound of pureed potato, rather than spending money on commercial carbohydrate pastes that don’t do the job any better.

Study finds no link between youth contact sports and cognitive, mental health problems

Adolescents who play contact sports, including football, are no more likely to experience cognitive impairment, depression or suicidal thoughts in early adulthood than their peers, suggests a new University of Colorado Boulder study of nearly 11,000 youth followed for 14 years.

Researchers uncover novel molecular clues for tumor aggression in neurofibromatosis type 1

Researchers at the Johns Hopkins Kimmel Cancer Center report that their study of tumor samples from people with the rare genetic syndrome neurofibromatosis type 1 (NF1) has uncovered novel molecular clues about which tumors are most likely to be aggressive in those with NF1

New guidance from oncology experts recommends tailored exercise prescriptions

New guidance from exercise oncology experts recommend systematic use of an "exercise prescription" by health care workers and fitness professionals in designing and delivering exercise programs that aim to lower the risk of developing certain cancers and best meet the needs, preferences and abilities of people with cancer.

Concussed athlete's brain may not fully recover even one year after return to play

How long does it take an athlete to recover from a concussion? New research has found an athlete's brain may still not be fully recovered one year after being allowed to return to play.

Skin's circadian clock is independent of the eyes or brain, study finds

Squids, octopuses, cuttlefish, amphibians, and chameleon lizards are among the animals that can change the color of their skin in a blink of an eye. They have photoreceptors in their skin that operate independently of their brain. The photoreceptors are part of a family of proteins known as opsins.

Brain's neural activity plays a role in human aging, life span

The brain's neural activity - long implicated in disorders ranging from dementia to epilepsy - also plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute at Harvard Medical School.

UCLA research identifies potential strategy that may halt Huntington's disease

A new study examining the role that star-shaped brain cells called astrocytes play in Huntington's disease has identified a potential strategy that may halt the disease and repair some of the damage it causes.

Hyperbaric oxygen therapy can relieve symptoms and side-effects of radiotherapy

Hyperbaric oxygen therapy can relieve self-reported symptoms and side-effects of radiotherapy against cancer in the pelvic region, a study shows. After 30-40 sessions in a hyperbaric chamber, many patients experienced reductions in bleeding, urinary incontinence, and pain alike.

New recommendations outline specific 'exercise prescriptions' for cancer survivors

A recent review of research, conducted by an international group of experts led by the University of British Columbia, has resulted in the development of new exercise guidelines for cancer survivors.

Scientists decipher assembly line of glutamate receptors

Rapid communication of neurons in the brain, as well as the ability to learn, fundamentally rely on neurotransmitter receptors located in the contact sites of neurons, the synapses. The most important receptors in the mammalian brain are glutamate receptors of the AMPA-type that generate the electrical signal required for fast communication between neurons.

Researchers outline new exercise recommendations for people living with and beyond cancer

It's well known that exercise is good for preventing and treating many forms of heart disease, but less commonly known are the benefits of physical activity for people living with and beyond cancer.
