Hi Dear,

Yes, Phisiology is a  branch of biology that aims to understand the mechanisms of living things. BSC hons in physiology  is  a three year course which deals with the study of living organism. However, After completion of just BSC it is difficult for you to get a government job as  a teacher. You can go for further studies and required qualification in the same field like b.ed, MSC, PHD etc.
