Biomedical engineering exploits physical physics to allow people to understand the human body. Examples include X-rays that give insight to the internal anatomy and PET that can give insight to the biochemistry within tissues.

History
Engineering became a field in the 1850s. The first Ph.D was given to J. Willard Gibbs at Yale who later developed physical chemistry. Engineering transformed in 1900s delivering electricity, bridges, steel and computers.

Human life expectancy increased in the last 100 years. In the 1700s, the average age of death was 40 years. 90% of people died of infectious diseases. The increase in lifespan is due to to higher quality of medication, antibotics, peniilin and vaccines. The affordable scale and production of drugs to a global audience is a contribution from biomedical engineers. The prevailing causes of cancer since 1997 are (1) heart disease and (2) cancer.
