Physics holds significance in the medical field playing a vital role, in the education and training of future doctors. Aspiring medical students often wonder why they are required to demonstrate proficiency in physics during their entrance exams. The reason lies in the connection between physics and medicine.


Physics encompasses the study of principles that govern the world encompassing the behaviour of matter and energy. In the realm a strong understanding of these principles is imperative for reasons.


1. Diagnostic Imaging; Medical imaging technologies, such as X rays MRI scans and CT scans heavily rely on physics principles. Doctors need to comprehend how radiation interacts with the body to accurately interpret these images. This understanding aids in diagnosing and treating conditions effectively.


2. Radiation Therapy; Physics plays a role in radiation therapy by facilitating targeting and destruction of cancer cells. Accurate calculations regarding radiation doses and an understanding of how radiation interacts with tissue are crucial for ensuring treatment while minimizing harm to healthy cells.

3. Biomechanics; Physics provides insights into understanding the mechanics of the body. This knowledge proves essential in fields like orthopaedics and rehabilitation as it allows physicians to diagnose disorders accurately. Additionally it helps design treatments and physical therapies, for patients suffering from conditions.


4. Cardiovascular Medicine; This field of medicine heavily relies on the principles of physics to comprehend how blood flows within the heart and blood vessels. Medical professionals utilize this understanding to diagnose and provide treatment, for heart related ailments.


5. Pharmacology; To effectively prescribe medications and determine correct dosages, one must have a comprehensive understanding of drug pharmacokinetics - how they are absorbed, distributed, metabolized, and excreted within the body. This requires a firm grasp of physical principles.
