Final answer:
During laparoscopy, the abdominal cavity is inflated with Carbon dioxide (CO2) to create pneumoperitoneum, facilitating a clear surgical field for the procedure.
Step-by-step explanation:
The abdominal cavity is inflated with a particular gas to create a pneumoperitoneum during minimally invasive surgery, such as laparoscopy. The gas used for this purpose is Carbon dioxide (CO2). Carbon dioxide is preferred because it is non-flammable, easily absorbed, and can be excreted by the lungs. This creates a working space for the surgeon by separating the abdominal wall from the organs below, providing better visibility and room to operate.
