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.
Biochemistry may be defined as the science concerned with the chemical basis of life. The cell is the structural unit of living systems. Therefore, biochemistry can also be described as the science involved with the chemical constituents of living cells and also the reactions and procedures they undergo.
