The expression is a trinomial, like the expressions which we've been factoring in this lesson. There is a small variation in this problem however -- the first term has a coefficient that is not 1.
Ventricular Phonation (Plica Ventricularis). This occurs when a great amount of muscle tension above the vocal folds is created in the laryngeal area causing an approximation of the false vocal folds.entricular Phonation (Plica Ventricularis). This occurs when a great amount of muscle tension above the vocal folds is created in the laryngeal area causing an approximation of the false vocal folds.
Ventricular Filling. Finally, ventricular filling is the terminal stage of the cardiac cycle. As its name states, this phase is when the ventricles start to fill with blood passed from the atria, meaning that the semilunar valves are closed and both the mitral and tricuspid valves are open.
