Organ-on-a-chip devices replicate human physiology using:

  1. Microfluidic channels
  2. Living human cells
  3. Mechanical stimuli
  4. All of these

Answer: All of these

Microphysiological systems mimic organ functions (lung, liver, gut) on chip-sized devices. Enable drug testing, disease modeling with human relevance, reducing animal experiments. DBT supports Indian research in this area. [[DBT Reports, NCERT Biology Class 12]]
