Tetanus requires hospitalization, treatment with human tetanus immune globulin (TIG), a tetanus toxoid booster, agents to control muscle spasm, aggressive wound care, and antibiotics. Metronidazole is the most appropriate antibiotic. The wound should be debrided widely and excised if possible.
Chemistry is also a physical science, and could be seen as a bridge between physical and life sciences. Chemical reactions happen in lifeforms like humans constantly, as studied in biochemistry, so understanding chemistry naturally leads to a better understanding of living organisms.
Physical science. Physical science, the systematic study of the inorganic world, as distinct from the study of the organic world, which is the province of biological science. Physical science is ordinarily thought of as consisting of four broad areas: astronomy, physics, chemistry, and the Earth sciences.
