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.
Women who engage in light physical activity and lessen their sedentary time may significantly reduce the risk of key health problems during pregnancy, according to a new University of Iowa-led study.
Cognitive behavioral therapies for insomnia (CBT-I) are increasingly being delivered online in order to improve accessibility.
New research highlights fathers' influence on childhood obesity risk through sperm changes, lifestyle, and parenting, urging inclusive prevention strategies.
A growing body of research suggests that a father's health before conception may play a larger role in child development than previously understood - and researchers are working to understand how a father's drinking before conception may affect offspring health and development.
Studies in mice reveal a new target for potentially treating and preventing life-threatening cardiovascular complications in the millions of patients with sleep apnea worldwide.
Alzheimer's disease and related dementias are expected to more than double by 2060. As June marks Alzheimer's and Brain Awareness Month, three University of Florida researchers are working to improve clinicians' ability to distinguish between these diseases - a critical step toward earlier diagnosis and better outcomes.
A pilot study published today in Communications Medicine demonstrates the potential of a new approach to treating anorexia nervosa - a disorder for which effective treatments have been significantly limited.
Perioperative anaphylaxis is a rare, life‑threatening condition during anesthesia. The unique setting – multiple drugs, patient draping, and altered physiology – causes higher mortality than anaphylaxis elsewhere.
Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength in adulthood.
A Mount Sinai-led research team has demonstrated that autoimmunity, where the body's immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of people.
Science and art have been brought together in a series of new projects led by a Kingston University academic, challenging the stigma surrounding the menopause and women's health through a groundbreaking body of work featured in several prestigious exhibitions this summer.
A study on 42,759 menstrual cycles shows that sleep quality affects menstrual health, with implications for physiological stability and individual variability.
Digital health tools, including wearables, provide critical data on menstrual health, enhancing understanding of hormonal fluctuations and women's well-being.
This review examines how gut keystone bacteria shape microbiome stability, disease risk, and responses to diet. It highlights why better identification methods, experimental validation, and precision diet-probiotic strategies are needed to restore gut homeostasis.
Megan Sweet slices tumors. A normal day in the lab finds the Virginia Tech graduate student with hands deep inside a refrigerated metal box, pulling a mounted mouse-grown tumor incrementally closer to a razor-sharp blade.
A rapidly advancing area of biomedical innovation is shining a spotlight on miR-128-3p, a small yet powerful molecule with the potential to reshape how diseases—especially cancer—are detected, monitored, and treated. This microRNA, part of a broader class of non-coding RNAs, plays a critical role in regulating gene activity and maintaining cellular homeostasis.
This systematic review found that yoga and Buddhist meditation were associated with favorable gut microbiota and metabolite profiles in four human studies involving healthy adults. However, because participants largely followed vegetarian or vegan diets and no randomized controlled trials were included, the findings cannot prove that meditation alone reshapes the gut microbiome.
A new review highlights how synthetic biology, AI, and spatial omics could transform ligand-receptor discovery from one-by-one searches into network-level mapping.
Researchers found that more than half of urban rats sampled from low-income communities in Salvador, Brazil, carried active pharmaceutical ingredients in their brain tissue. These pollutants were associated with altered zoonotic infection patterns, including lower Leptospira infection probability in rats carrying azithromycin and higher Capillaria infection probability in rats carrying citalopram.
Bone is continuously renewed through a process known as bone remodeling, in which osteoblasts (bone-forming cells) build new bone, while osteoclasts (bone-resorbing cells) remove older mineralized tissue.
