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.
The new study shows that the fatigue that marathoners and other extreme athletes feel at the end of a race is caused by a tiny leak inside their muscles that probably also saps the energy from patients with heart failure.
Researchers from the Boston University School of Medicine (BUSM) have demonstrated that in mice, the use of barbells may be as important to losing weight and improving health as the use of running shoes.
People with unrelenting pain don't only suffer from the non-stop sensation of throbbing pain.
An unexpected finding turned out to be a clue leading researchers at Washington University School of Medicine in St. Louis to propose a new treatment approach for Niemann-Pick disease, a rare, deadly neurodegenerative disorder.
A new study from the Monell Center increases understanding of the biological mechanisms responsible for the nausea and vomiting that often afflict patients undergoing chemotherapy.
A protein has been found that influences the response of the heart to a lack of oxygen and blood flow, such as occurs during a heart attack, a team of Yale School of Medicine researchers report in Nature.
An enzyme released by mast cells in the lungs appears to play a key role in the tightening of airways that is a hallmark of asthma pointing to a potential new target for treatment against the illness.
A study at Rush University Medical Center in Chicago published this week in the online version of Biophysical Journal proposes that bubbles may control the opening and closing of ion channels.
Sequences of DNA in the human genome that originated from ancient viral infections have some surprising effects on our bodies and are even essential for a healthy pregnancy, according to an article in the February issue of Microbiology Today.
A multi-center research project to investigate severe asthma has found a key physiological difference between severe and non-severe forms of the disease, a finding that could help explain why those with severe asthma do not respond well to treatment.
An enzyme released by mast cells in the lungs appears to play a key role in the tightening of airways that is a hallmark of asthma pointing to a potential new target for treatment against the illness.
