What's the difference between catheter and fluid?

Catheter


Definition:

  • (n.) The name of various instruments for passing along mucous canals, esp. applied to a tubular instrument to be introduced into the bladder through the urethra to draw off the urine.

Fluid


Definition:

  • (a.) Having particles which easily move and change their relative position without a separation of the mass, and which easily yield to pressure; capable of flowing; liquid or gaseous.
  • (n.) A fluid substance; a body whose particles move easily among themselves.

Example Sentences:
