What's the difference between ejection and protrusion?

Ejection


Definition:

  • (n.) The act of ejecting or casting out; discharge; expulsion; evacuation.
  • (n.) The act or process of discharging anything from the body, particularly the excretions.
  • (n.) The state of being ejected or cast out; dispossession; banishment.

  • (17) The results showed that the shortening fractions and ejection fractions were significantly depressed in the experimental embryos.
  • (18) Global left ventricular ejection fraction (LVEF) was obtained by radionuclide angiography and analyzed with an automatic detection program.
  • (19) Thus, patients are likely to live longer after CABG if they have left main disease; three-vessel disease with left ventricular dysfunction (ejection fraction less than 50%), class III or IV angina, provocable ischemia, or disease in the proximal left anterior descending coronary artery; two-vessel disease with proximal left anterior descending artery involvement; and two-vessel disease with class III or IV angina as well as either severe left ventricular dysfunction alone or moderate left ventricular dysfunction together with at least one proximal lesion.
  • (20) The maintenance of adequate blood circulation requires a sufficient ventricular contractility; in addition, to eject blood, the ventricles must first receive a sufficient volume, requiring a low diastolic stiffness.

Protrusion


Definition:

  • (n.) The act of protruding or thrusting forward, or beyond the usual limit.
  • (n.) The state of being protruded, or thrust forward.

Example Sentences:

  • (5) Anterior lenticonus is a rare condition, in which there is a conical or spherical protrusion of the anterior surface into the anterior chamber.
  • (6) The phenomenology of various protrusions, including fimbria, is described, and the effect of cultivation conditions (continuous culture, periodic culture) and growth phases on their emergence was elucidated.
  • (7) The uveal protrusion was replaced and a deep corneoscleral block was removed in front of the scleral spur in three cases, and electrocoagulation of the anterior edges of the trabeculectomy fistula was done in other three cases.
