Fyziológia

Fyziológia is the natural science that studies the functions of living organisms and their parts. It seeks to understand how organs and tissues perform their roles and interact to sustain life, growth, reproduction, and adaptation. The term derives from the Greek physio- meaning nature or growth and -logia meaning study of. In Slovakia and in the broader scientific context, fyziológia encompasses the functioning of humans, animals, and plants and provides the foundation for medicine, veterinary science, and biology.

Subfields and approaches include general physiology, cellular and molecular physiology, and organ-system disciplines such as neurophysiology, cardiovascular, respiratory, renal, digestive, endocrine, and musculoskeletal physiology, as well as plant physiology. Modern fyziológia emphasizes integrative, systems-level understanding and often uses comparative studies across species to identify universal principles governing function and homeostasis.

Researchers employ a range of techniques, including electrophysiology, imaging, biochemistry, molecular biology, and omics approaches, together with in vivo and in vitro experiments. Computational modeling and systems biology are increasingly used to simulate physiological processes and predict responses to perturbations.

Fyziológia informs medicine, pharmacology, and rehabilitation, and it underpins advances in agriculture, animal science, and biotechnology. Knowledge of physiological mechanisms guides diagnosis and therapy, drug development, and strategies to improve crop resilience and livestock health, as well as responses to environmental stress.

Historically, the development of fyziológia traces from classical natural philosophy to modern science. Early contributors such as Claude Bernard helped establish the notion of the internal environment, while Walter Cannon popularized homeostasis. The 19th and 20th centuries saw rapid advances in experimental methods, electrophysiology, and cellular and molecular approaches that broadened the field’s scope.
