If you want to pursue a more specialized education in physiology, then yes, you can definitely do that after completing your B.Sc.

This is a postgraduate program that will delve deeper into the physiological processes of living organisms. It can equip you with advanced knowledge and research skills in the field.

Depending on your B.Sc. specialization and interests, you could pursue a Master's degree in a discipline related to physiology, such as:

• Neuroscience
• Biochemistry
• Biotechnology
• Human Biology
• Exercise Physiology
  
  If you are interested in applying your existing B.Sc. knowledge to a job that touches on aspects of physiology there are possibilities too:
  
  
  • Research Assistant: You could assist researchers in labs working on areas related to physiology, even with a general B.Sc. degree.
    
    
  • Healthcare fields: Depending on your B.Sc. specialization, you might explore roles in hospitals, clinics, or research institutions that involve some understanding of physiology such as:
    
    
    • Lab technician (with additional training)
    • Assistant to a physiotherapist (with additional training)
