A section of Biology (ISSN 2079-7737).

Section Information

The definition of "Physiology" is not trivial because this field of biology is not restricted to a certain research topic, method, or organ. Instead, it can be best defined by the central question asked in any physiological research, "How does it work?".

Long ago, methods of classical physiology were mainly physical and electrical, but today physiologists use all kinds of modern scientific techniques to discover the exact mechanism behind a biological process. Often, specific functional measurements are combined with molecular biological or advanced microscopic techniques.

The subjects of physiological research are virtually unlimited, the spectrum ranging from biological molecules, organelles, cells, tissues, and organs to whole organisms. The large field of neurophysiology is excluded here, because the topic is widely covered by specific journals. The list of keywords below is arbitrary and rough, and therefore should not be considered to exclude topics not listed here.


• Cellular and subcellular function
• Cardiovascular system and microcirculation
• Epithelial transport and barrier
• Lung and gas exchange
• Gastrointestinal function
• Kidney and homeostasis
• Endocrine and metabolism
• Muscle, exercise and sport
• Stress response
