What's the difference between distend and distention?

Distend


Definition:

  • (v. t.) To extend in some one direction; to lengthen out; to stretch.
  • (v. t.) To stretch out or extend in all directions; to dilate; to enlarge, as by elasticity of parts; to inflate so as to produce tension; to cause to swell; as, to distend a bladder, the stomach, etc.
  • (v. i.) To become expanded or inflated; to swell.

Distention


Definition:

  • (n.) The act of distending; the act of stretching in breadth or in all directions; the state of being Distended; as, the distention of the lungs.
  • (n.) Breadth; extent or space occupied by the thing distended.
