Human physiology is the analysis of how the human body functions at the cellular, tissue, organ, and system level. It encompasses various physiological systems such as the nervous system, cardiovascular system, respiratory system, endocrine system, digestive system, and renal system. Some key aspects of human physiology include: Homeostasis: The maintenance of a stable internal environment within the body, despite changes in the external environment. Cellular and Molecular Physiology: The study of how cells and molecules in the body function, interact, and communicate with each other. Energy Metabolism: The analysis of how the body uses and produces energy for different physiological processes. Neurophysiology: The analysis of the nervous system and how it functions to control and coordinate body functions. Cardiovascular Physiology: The analysis of the heart and blood vessels, and how they function to transport oxygen, nutrients, and other substances throughout the body. Respiratory Physiology: The analysisof how the lungs and respiratory system function to exchange gases (oxygen and carbon dioxide) with the external environment. Endocrine Physiology: The analysis of how hormones and other signalling molecules regulate various physiological processes in the body. Understanding human physiology is essential for maintaining good health, preventing diseases, and developing new medical treatments. Human oral mouth physiology refers to the analysis of the structure, function, and mechanisms of the mouth and its related structures. The oral cavity is responsible for a number of functions, including biting, chewing, swallowing, and speaking. Human physiology of oral cavity is important for maintaining good oral health. Practicing good oral hygiene habits such as brushing and flossing regularly, visiting the dentist regularly, and eating a healthy diet can help prevent oral health problems and maintain overall health and well-being. Human physiology and oral health are closely related.
