It applies the design and problem solving skills of engineering with medical and biological sciences to improve diagnosis of healthcare and treatment of diseases.Compared to other engineering disciplines, Biomedical engineering has recently surfaced as its own discipline; this process is common as a new field transitions from being an interdisciplinary specialization among already-established fields, to being considered a field in itself.The work in BME consists mostly of research and development; this work spans a broad of subfields such as Bioinstrumentation, Biomaterials, Cellular, Tissue, Genetics Engineering, Biomechanics, Clinical Engineering, Orthopedic Bioengineering, Rehabilitation Engineering, and Systems Physiology. Some of BME applications include the development of biocompatibility materials, and therapeutic medical devices. These range from clinical equipments to micro-implants. Some medical equipment includes MRI and EEG. .The field of Biomedical engineering is highly interdisciplinary; it is overlapping with other engineering disciplines and medical fields. Because of this diversity, it is typical for a biomedical engineer to concentrate on a specific subfield or group of related subfields. There are many different taxonomic breakdowns within BME, as well as varying views about how best to organize them and manage any internal overlap; the main major areas of BME could be found in the earlier paragraph.Oftentimes, disciplines within BME are classified by their association(s) with other, more established engineering fields, which can include: Chemical Engineering that is associated with biochemical, molecular and tissue engineering. Electrical engineering is often associated with bioelectrical, neural engineering, bioinstrumentation, optical engineering and medical devices. Mechanical engineering is associated with biomechanics, medical devices and modeling of biological systems. less

It came to be in its existence in the 19th century as scientists were first discovering how to build and operate steam engines. Thermodynamics deals with the large scale response of a system which we can observe and measure in experiments. Small scale gas interactions are described by the kinetic theory of gases. The methods complement each other; some principles are easier to understand in terms of thermodynamics and some principles are easily explained by kinetic theory.There are three principal laws of thermodynamics:Each law leads to the definition of thermodynamic properties which aid us to understand and predict the operation of a physical system. The zeroth law:The zeroth law of thermodynamics involves some simple definitions of thermodynamic equilibrium. Thermodynamic equilibrium leads to the large scale definition of temperature, as opposed to the small scale definition related to the kinetic energy of the molecules. The first law of thermodynamics:It relates the various forms of kinetic and potential energy in a system to the work which a system can perform and to the transfer of heat. This law is sometimes taken as the definition of internal energy, and introduces an additional state variable, enthalpy. The first law of thermodynamics allows for many possible states of a system to exist. But experience indicates that only certain states occur. This leads to the second law of thermodynamics and the definition of another state variable called entropy. The second law of thermodynamics:It stipulates that the total entropy of a system plus its environment can not decrease; it can remain constant for a reversible process but must always increase for an irreversible process. less
