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.

How cells communicate focus of new research

Scientists at the University of Liverpool have been awarded £5 million to investigate how cells respond to stimuli such as stress and UV radiation.

First chemical evidence of a sperm recognition system in the oviducts of pigs

Adding another layer of competition to the mating game, scientists are reporting possible biochemical proof that the reproductive system of female mammals can "sense" the presence of sperm and react to it by changing the uterine environment.

Nitrite/nitrate-rich foods may help in heart attack survival

Nitrite/nitrate found in vegetables, cured meats and drinking water may help you survive a heart attack and recover quicker, according to a pre-clinical study led by a cardiovascular physiologist at The University of Texas Health Science Center at Houston.

Overeating alters the core mechanism of the body clock

Our body's 24-hour internal clock, or circadian clock, regulates the time we go to sleep, wake up and become hungry as well as the daily rhythms of many metabolic functions.

Brain chemistry and genes dictate nicotine cravings

Individual brain chemistry and genes could be key to understanding why some people become addicted to nicotine and why the chemical compound's effects appear to diminish at night, University of Colorado at Boulder researchers say.

UMC takes part in largest ever study of child and human health

The University of Mississippi Medical Center has been selected as one of 22 study centers nationwide by the National Children's Study (NCS), the largest study of child and human health ever conducted in the United States, to assess the effects of environmental and genetic factors on child and human health in the country.

Study may aid pancreatic cancer patients' response to chemo drugs

Pancreatic cancer patients face the worst survival rates compared to all other forms of human cancer as the disease is nearly impossible to diagnose at an early stage when successful treatments might be possible.

How can some people live at high altitudes and thrive while others struggle?

The answer for Tibetans who live at altitudes around 14,000 feet is increased nitric oxide (NO) levels. High levels of NO circulate in various forms in the blood and produce the physiological mechanisms that cause the increased blood flow that maintains oxygen delivery despite hypoxia - low levels of oxygen in the ambient air and the bloodstream.
