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.

Blood pressure regulation in males and females is different, scientists say

Another difference between females and males appears to be a key mechanism in how they become hypertensive, scientists say, and consequently which antihypertensives should be most effective for them.

UChicago and Rush secure NIH grant to launch the Chicago Chronic Condition Equity Network

The University of Chicago and Rush University have received a $20M, five-year grant from the National Institutes of Health to establish a Center for Multiple Chronic Diseases Associated with Health Disparities.

Research reveals how daily circadian rhythms help to change heart function

A new study has shown how circadian rhythms in heart cells help to change heart function over the course of the day and may explain why shift workers are more vulnerable to heart problems.

New risk measure can better predict pandemic spread than other models

COVID-19 is not the flu. The disease caused by the novel SARS-CoV-2 virus is more transmissible, and deadlier, than most influenza epidemics we've encountered in our lifetimes, and scientists and physicians are still learning new things about the disease and its long-term effects.

Study unravels new mechanism for muscle repair after physiological damage

Muscle is known to regenerate through a complex process that involves several steps and relies on stem cells. Now, a new study led by researchers at Pompeu Fabra University (UPF, Spain)/Centro Nacional de Investigationes Cardiovasculares (CNIC, Spain)/CIBERNED (Spain) and Instituto de Medicina Molecular João Lobo Antunes (iMM, Portugal), published on 15 October in the journal Science, describes a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fiber nuclei, and independently of muscle stem cells.

Researchers identify neurons and signaling pathways that make sexually receptive females more active

Scientists have known for a century that female animals become more active just as they are about to ovulate, a behavior that evolved to enhance their chances of mating when they are fertile.

Research reveals 3D structure of cell receptor with critical role in health and disease

Cells communicate with their environment via receptors on their surface. When a protein approaches these receptors, they can pass along a message to the inside of the cell, for example the instruction to grow which can lead to tumor formation.

COVID-19 linked to newborn complications

A recent study discusses whether pregnant women with the COVID-19 are at a higher risk for poor outcomes for themselves and their babies.

Mothers pass on the legacy of stress exposure to future generations

A mother's response to stress can even influence her grandchildren. Biologists at the University of Iowa found that roundworm mothers subjected to heat stress passed, under certain conditions and through modifications to their genes, the legacy of that stress exposure not only to their offspring but even to their offspring's children.

Long stays in space appear to cause brain damage

Spending a long time in space appears to cause brain damage. This is shown by a study of five Russian cosmonauts who had stayed on the International Space Station.

Genetics can influence a person's response to Alzheimer's disease pathology, research suggests

A recently released paper from the Department of Physiology and Sanders-Brown Center on Aging (SBCoA) at the University of Kentucky College of Medicine suggests that your genetics can influence your response to Alzheimer's disease pathology.

Neuroscientists unveil detailed atlas of brain cells

When you clicked to read this story, a band of cells across the top of your brain sent signals down your spine and out to your hand to tell the muscles in your index finger to press down with just the right amount of pressure to activate your mouse or track pad.

Machine learning and high-powered microscopes provide detailed snapshots of cells' inner machinery

Open any introductory biology textbook, and you'll see a familiar diagram: A blobby-looking cell filled with brightly colored structures – the inner machinery that makes the cell tick.

Toxic fatty acids trigger cell death in damaged neurons

Cells that normally nourish healthy brain cells called neurons release toxic fatty acids after neurons are damaged, a new study in rodents shows.

Elevated allostatic load may impact treatment completion and breast cancer survival outcomes

Elevated allostatic load was associated with a lower likelihood of completing chemotherapy and a lower overall survival rate in patients with lymph node-positive or high-risk lymph node-negative HER2-negative breast cancer, according to results presented at the 14th AACR Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held online October 6-8, 2021.

COVID-19 survivors under 40 more likely to recover from smell and taste loss, study finds

Sense of smell or taste returns within six months for 4 out of every 5 COVID-19 survivors who have lost these senses, and those under 40 are more likely to recover these senses than older adults, an ongoing Virginia Commonwealth University study found.

Racism a strong factor in Black women’s high rate of premature births, study finds

The tipping point for Dr. Paula Braveman came when a longtime patient of hers at a community clinic in San Francisco's Mission District slipped past the front desk and knocked on her office door to say goodbye. He wouldn't be coming to the clinic anymore, he told her, because he could no longer afford it.
