Understanding what is taught in the first year helps reduce anxiety and improves academic planning.
This blog explains the 1st Year MBBS subjects Anatomy, Physiology and Biochemistry in a clear and simple way. It is updated for 2026 and written especially for beginners who want to know what to expect in their first year of medical college.
1st Year MBBS Subjects Explained 2026 – Anatomy, Physiology and Biochemistry
Overview of 1st Year MBBS Curriculum
The MBBS curriculum in India is regulated by the National Medical Commission. The first year focuses on understanding the normal structure and function of the human body at different levels.
The three core subjects taught in the first year are:
Anatomy Physiology Biochemistry
These subjects are interconnected and form the base for second and third year clinical subjects such as pathology, pharmacology, medicine and surgery.
Anatomy in 1st Year MBBS
What is Anatomy
Anatomy is the study of the structure of the human body. It helps students understand how different organs, tissues and systems are arranged and related to each other.
Anatomy is considered one of the most detailed and demanding subjects in the first year.
Major Divisions of Anatomy
Gross Anatomy Embryology Histology Neuroanatomy
Key Topics Covered
Upper limb and lower limb Thorax and abdomen Head and neck Brain and spinal cord Development of organs Microscopic structure of tissues
Teaching Methods
Lectures and demonstrations Cadaver dissection Histology slide examination Practical anatomy sessions
Why Anatomy is Important
Anatomy is essential for understanding surgery, radiology and clinical procedures. Strong anatomical knowledge helps students perform better in later clinical years and internships.
Physiology in 1st Year MBBS
What is Physiology
Physiology deals with the normal functioning of the human body. While anatomy tells you what the body looks like, physiology explains how it works.
It is a concept based subject that focuses on understanding rather than memorization.
Major Systems Studied
Blood and immune system Cardiovascular system Respiratory system Digestive system Renal system Nervous system Endocrine system
Learning Approach
Concept based lectures Practical experiments Graph interpretation Clinical correlation
Why Physiology is Important
Physiology helps students understand disease mechanisms in later years. A strong foundation in physiology is crucial for subjects like pathology, pharmacology and medicine.
Biochemistry in 1st Year MBBS
What is Biochemistry
Biochemistry studies chemical processes inside the human body. It focuses on molecules, enzymes and metabolic pathways that keep the body functioning.
Many students find biochemistry challenging at first, but it becomes easier with regular revision.
Core Topics Covered
Carbohydrate metabolism Protein metabolism Lipid metabolism Enzymes and cofactors Vitamins and minerals Molecular biology basics
Practical Learning
Laboratory experiments Clinical case interpretation Understanding lab reports
Importance of Biochemistry
Biochemistry helps in understanding lab investigations and metabolic disorders. It is highly useful in clinical practice and diagnostics.
How 1st Year MBBS Subjects Are Assessed
Internal assessments Practical examinations University theory exams Viva voce
Marks are divided between theory and practical . Regular attendance and internal exams are important for eligibility.
