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.
Biology brings Chemistry to Life. Organic chemistry is the chemistry of carbon-based molecules. Part of the backbone or skeletal structure of Organic molecules is made of one or more carbon atoms. The application of chemical systems, structures, and processes to living systems is known as Biochemistry.
