Physiologists can study how organisms' organs work together to make things happen. For example, in humans, digestion of food hormones and other chemicals occurs in the stomach, liver, and pancreas. Muscle contraction is caused by chemical messages sent by nerves in that muscle. By learning how the body functions normally, physiologists and doctors can better understand what happens when organs are not functioning properly. For example, understanding how the thyroid gland works has helped treat goiter. Research in the circulatory and nervous system has helped physicians understand diseases such as heart disease, stroke, and high blood pressure. It has helped me heal. Central to physiological function are biophysical and biochemical processes, homeostatic control mechanisms, and intercellular communication. A physiological state is a state of normal functioning. Pathology, on the other hand, refers to abnormal conditions, including human disease. The Nobel Prize in Physiology or Medicine is awarded by the Royal Swedish Academy of Sciences for outstanding scientific achievements in medicine-related physiology. Human physiology seeks to understand the mechanisms that keep the human body alive and functioning through the scientific study of the nature of the mechanical, physical, and biochemical functions .The main level of focus in physiology is at the level of organs and systems within systems. The endocrine and nervous systems play important roles in the reception and transmission of signals that integrate animal functions. Homeostasis is an important aspect of both plant and animal interactions. Integration, the biological basis of the study of physiology, relates to the intersection of many functions and attendant morphologies of the human system. This is achieved through communication that takes place in a variety of electrical and chemical ways. Changes in physiology can affect an individual's mental function. Examples of this are the effects of certain drugs and toxic concentrations of substances. Behavioural changes as a result of these substances are often used to assess people's health. Much of the foundation of our knowledge in human physiology has been provided by animal experiments. Because form and function are frequently combined, physiology and anatomy are closely related and are studied in parallel as part of medical research. Physiology is the science of life. It is a field of biology that aims to understand the mechanisms of living organisms, from the basics of cell functions at the ionic and molecular level the study of physiology helps we understand how the body functions healthily and how it responds and adapts to the challenges of everyday life. It also helps determine what is wrong with disease, facilitating the development of new treatments and policies to maintain human and animal health. The emphasis distinguishes physiology from other life sciences. Physiologists at universities, research institutes, biotech companies, and the pharmaceutical industry around the world are working to advance our understanding of how the body works. Physiology is an exciting and dynamic field that underpins translational and clinical medicine. It also forms an interface between the natural and life sciences. Physiologists study all aspects of how the human and other animal bodies work. Some physiologists study the behaviour of individual proteins in individual cells. Others study the interactions of cells in tissues, organs, and systems, or examine the integration of these systems to control complex whole organisms. This research forms the basis of many biological and clinical sciences, including medicine and veterinary medicine.
