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.
Research shows that dietary potassium plays a vital role in blood pressure regulation, emphasizing the need for a balanced intake of sodium and potassium.
New research from the University of Waterloo suggests increasing the ratio of dietary potassium to sodium intake may be more effective for lowering blood pressure than simply reducing sodium intake.
Children do not appear to develop cooking skills merely by observing their parents’ food skills, even when those skills are high. Instead, early active involvement in meal preparation may be key to building lasting cooking abilities.
A University of Michigan research team has used AI to help deliver exercise "snacks" to kids with autism.
Bone regeneration continues to be a critical challenge in tissue engineering, with unpredictable outcomes often hindering clinical application. Current strategies overlook key factors such as donor differences and biological sex, both of which play a significant role in fracture healing.
Even in the case of uncomplicated infections, the body prepares itself early on for the possibility of a more severe course. A research team from the Technical University of Munich (TUM) and Helmholtz Munich has now uncovered this mechanism.
A team of researchers led by Dr. Kim V. Narry, director of the Center for RNA Research at the Institute for Basic Science (IBS), has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics.
Parkinson's doesn't just affect movement and the brain - it may also impact the heart, according to new research from the University of Surrey. Scientists from Surrey's School of Veterinary Medicine suggest that targeting a key protein outside of the brain could help manage Parkinson's-related heart issues.
The Icahn School of Medicine at Mount Sinai has launched the AI Small Molecule Drug Discovery Center, a bold endeavor that harnesses artificial intelligence (AI) to revolutionize drug development.
A new study by McGill University researchers yields insights into how the disruption of calcium transport in the brain is linked to autism and intellectual disability.
Gene therapy, a technique that is revolutionizing the treatment of multiple genetic conditions, including eye and muscle diseases and blood disorders, requires efficient and specific delivery of the genetic material to the tissue and cell type of interest.
Caffeine combined with beetroot juice significantly improves both initial and repeated 1000-meter running performance in non-athlete men. Body fat percentage, sleep duration, and nutrition emerge as key factors influencing endurance outcomes.
Ever wondered what happens to your body when you take those trendy ice baths? Scientists at the University of Ottawa just found out, and it's pretty fascinating.
Bone fracture healing is a highly coordinated process involving inflammation, fibrovascular formation, and mineralization.
In this interview Prof. Dr. Kristina Kusche-Vihrog speaks about the nanomechanics of living cells and their implications for cardiovascular disease.
Researchers at the University of Tokyo reveal the way our legs adapt to fast movements. When people hop at high speeds, key muscle fibers in the calf shorten rather than lengthen as forces increase, which they call "negative stiffness." This counterintuitive process helps the leg become stiffer, allowing for faster motion. The findings could improve training, rehabilitation, and even the design of prosthetic limbs or robotic exoskeletons.
New mums should be strongly encouraged to begin clocking up at least two hours of moderate to vigorous intensity physical activity such as brisk walking and muscle strengthening exercises each week in the first three months after birth, when physically able, to improve health and well-being, say experts in a new guideline published by the British Journal of Sports Medicine.
Past studies have shown that the human sweet taste receptor conveys sweet perception in the mouth and may help regulate glucose metabolism throughout the body.
After every meal, the intestines perform an action called peristalsis - moving food through their hollow interiors with coordinated contractions and relaxations of the smooth muscle.
A team of researchers from the Hospital del Mar Research Institute, the Universitat Autònoma de Barcelona and the Pompeu Fabra University has developed a new tool that allows modifying these NK cells to make them immune to the tumor’s defense mechanism.
