Medical Degree Program in China - Human Body Physiology
Physiology is a branch of biological science, which is a science of studying the life activities of the organism and the function of each part of the body. The task of human physiology is the study of all the systems of the body's organs and cells of normal activities, especially the internal mechanism of the various organs, the function of the cells appeared, and interactions between different cells, organs and systems to connect with each other, and explaining human as a whole, the functional activity of it is how to coordinate and restrict each other, so as to maintain normal life activities in the complex and changeable environment.
The structure and function of the human body is very complicated, and the basic component of the human body is the cell and Intercellular substance. Functional and structural similarity between the cells and the cell, organically combined to form a specific function of the organization. Various tissues are combined to form an organ with certain morphological characteristics and physiological functions. Such as skin, muscle, heart, liver, brain, etc.. The structural characteristics and functional adaptation of the organ. In order to be able to complete one or several physiological functions and the composition of a number of organs is called system. Such as mouth, pharynx, esophagus, stomach, intestines, digestive gland and other components of the digestive system, nose, pharynx, larynx, trachea, bronchus, lung composition of respiratory system. The whole body can be divided into 8 systems: motion system, circulatory system, respiratory system, digestive system, urinary system, reproductive system, nervous system and endocrine system. The human body is such a complete unity, which is composed of many organs and systems. The human body each system can closely coordinate and coordinate activities, is due to the neural and humoral regulation, especially the role of neural regulation.
Human physiology is a natural science, the functional activities of the human body of any theory or hypothesis is only from the actual observation to, and must through perfecting the design of experiments to test and revision and development, so that more in-depth understanding on the human body's physiological function to, increasingly accurate. But human physiology is different from physical, chemical and other general natural science, its experimental method has its own characteristics. Experimental study of the 17th century primary science, the organisms were observed using the method and technology of physics and chemistry; thereafter physiology method is improved with the development of mathematics, physics, etc in basic science and applied technology.
