What procedure involves withdrawing fluid from a body cavity?

• A. Biopsy
• B. Thoracentesis
• C. Endoscopy
• D. Dialysis

Answer: (B)

Removing fluid from a body cavity is a targeted procedure to access a space around organs for relief or analysis. The one that specifically pulls fluid from the chest’s pleural space is thoracentesis. In this procedure, a needle or small catheter is inserted through the chest wall into the pleural cavity to withdraw fluid. It’s often done to relieve shortness of breath from fluid buildup (pleural effusion) and to test the fluid for infection, cancer, or chemical makeup. Biopsy, by contrast, collects tissue samples rather than fluid. Endoscopy uses a scope to visualize internal surfaces, not remove fluid. Dialysis cleans blood rather than removing fluid from a body cavity.
