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.
This interview uncovers how exercise may reduce cancer cell viability, with insights into adipose interactions and innovative 3D culture systems.
A meta-analysis of 32 studies and 43,618 adults presented at this year's European Congress on Obesity in Istanbul, Turkey (12-15 May) shows that use of new classes of obesity drugs for weight loss is associated with a clinically relevant drop in blood pressure (BP): a 0.34 mmHg reduction in systolic BP per 1\% weight loss.
A study led by a University of Louisville School of Medicine pediatrics and child neurology researcher reveals how a specific signaling mechanism in microglia, the brain's immune cell, can regulate anxiety and grooming behaviors. These behaviors are core symptoms of autism and obsessive-compulsive spectrum disorders.
An unprecedented study led by researchers at the University of Malaga proposes a new antiviral strategy against SARS-CoV-2 -the virus responsible for causing COVID-19 disease- based on a treatment that combines two complementary approaches, capable of attacking the virus simultaneously, forcing its instability and hindering its ability to adapt.
An analysis of biological clocks throughout the human body suggests that too few hours of sleep-and too many-may speed aging in the brain, heart, lung, and immune system and is associated with a wide range of diseases.
A long‑overlooked stretch of the human genome appears to play a distinct role in shaping the social and stereotypic repetitive behaviors that define Autism Spectrum Disorder (ASD), without affecting learning or other cognitive abilities, according to a major new study published in Nature.
Cognitive pressure disrupts muscle control and blood flow, highlighting its role in physical performance during low-intensity motor activities.
A University of California, Riverside preclinical study is shedding light on a long-observed but poorly understood phenomenon: chronic cannabis users tend to have lower body weight and a reduced risk of developing type 2 diabetes, despite the drug's well-known tendency to increase appetite.
A BMJ systematic review of 59 human studies found no evidence supporting causal links between aluminum-adjuvanted vaccines and serious or long-term outcomes such as autism spectrum disorder, asthma, autoimmune conditions, or other chronic illnesses. The most consistent adverse events were uncommon, local, self-limited persistent nodules or granulomas, likely reflecting delayed-type hypersensitivity.
Qureight, an end-to-end imaging CRO that provides enterprise-grade imaging and precision endpoints for clinical trials with a focus on lung and heart disease, today announced it has established a Scientific Advisory Board (SAB) focused on pulmonary hypertension (PH).
Included with every Gastrolyzer® range order, Bedfont® Scientific Limited provides practical resources designed to support and simplify hydrogen and methane breath testing (HMBT).
Cardiovascular disease remains a leading global health burden, yet many preclinical systems still struggle to predict how candidate drugs will perform in the human heart.
A small exploratory study of collegiate football players found that non-concussive head impacts are correlationally linked to acute and season-long shifts in gut microbiome composition, with changes most pronounced 48–72 hours after significant impacts. However, most associations weakened after correction for multiple testing, and the authors stress the findings are preliminary and hypothesis-generating.
MUSC researchers are tackling MASH, or metabolic dysfunction-associated steatohepatitis, a liver disease affecting hundreds of millions worldwide.
When danger lurks, instinct keeps us safe. It compels us to run from a burning building or wrestle a knife-wielding attacker to the ground. It also adjusts our body physiology to support these behaviors.
Short QT syndrome is a genetic disease that leads to sudden cardiac death at a young age. Mutations in the SLC4A3 gene, which regulates bicarbonate-chloride exchange, were recently described as a potential cause. An international research team, including a group from Ruhr University Bochum, Germany, investigated this possibility.
Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-approved therapy that uses brief magnetic pulses to treat depression, particularly in patients who do not respond to medication.
Can a compound derived from a common kitchen ingredient help support muscle health during aging? A new study suggests it can.
Involving a collaboration with 118 investigators contributing from 89 institutions, scientists from Queen Mary University of London's Precision Healthcare University Research Institute and Berlin Institute of Health (BIH) at Charité have led the world's largest study on the genetic regulation of blood proteins.
A new study presented today at the European Stroke Organisation Conference (ESOC) 2026 suggests that both very low and very high resting heart rates are linked with an increased risk of stroke.
