MS in Biomedical Engineering at CMC Vellore [ Best Program]

The Bioengineering program at CMC-Vellore is unique in India in offering Postgraduate engineering education in a medical institution. It imparts training in engineering analysis, design and prototyping within a multi- faceted medical institution. Its aim is to bring some of the best global practices in interdisciplinary biomedical engineering R&D to address healthcare problems inIndia.
Bioengineering at CMC
Bioengineering Involves basic science and applied research in medical instrumentation, prostheses, mathematical analysis of physiological processes, biomechanics of musculoskeletal
systems, rehabilitation engineering etc. Bioengineering has engineering at its core, and includes the disciplines of physics, mechanics, electronics, and computational methods applied to
physiology and medicine.
The Department
The Bioengineering department at CMC-Vellore works closely with several other departments in CMC and significant work has been in Physiological Measurements, Prostheses and Assistive Devices, Electrodiagnostics, Neuorehabilitation technology etc. The department has electronics and mechanical fabrication and testing labs as well as embedded and GUI software development facilities. Devices developed in the department are in use in clinical departments and research labs in CMC and other institutions. The Bioengineering department at
CMC is a participant in a three institution M.Tech. (Clinical Engineering) and Ph.D. (Medical Devices) initiative, jointly run by IIT-Madras, SCTIMST-Trivandrum and CMC-Vellore. The
admissions for those programmes are advertised separately.

How the Body Handles Drugs USING Kidney and Liver-INTERESTING FACT

Concentrations of Drugs in the Blood are a Balance Between Input and Output

  • The concentrations of all chemicals in your body are the result of a balance between input and output.
  • For drugs the input is usually a steady injection through an intravenous (IV) line or a periodic uptake through pills taken at regular intervals.
  • The output of drugs is mainly through 2 organs, the liver and kidney.
  • When the output equals the input a steady-state is attained and the concentration will no longer change:

Basic Kidney Anatomy

  • Kidneys paired, about 150 gm each
  • Urine forming units:
    • Cortex
    • Medulla (lobed: renal pyramids)
    • Cortex and medulla composed chiefly of nephrons and blood vessels
    • Supplied by renal arteries (branches of descending aorta) and renal veins (branches of inferior vena cava)
  • Urine collecting and expelling units:
    • Calyces
    • Renal pelvises
    • Ureters
    • Bladder
    • Urethra

Although the Kidneys are Tiny Organs They Receive 25% of the Cardiac Output
