The AV valves close first, then the semilunars open and close, then the AV valves open
You can find this answer by Googling that question. But, as someone who answers questions, I'll write it within my own words.
An ectopic pregnancy is when the egg is attached somewhere else aside from the uterus; the normal resting spot for the fertilized egg to begin growing. Usually, in an ectopic pregnancy, the egg goes into a fallopian tube which is obviously not where the egg is meant to be growing, so the embryo usually cannot form and continue to grow. Since the egg is already inside a tube, there is no possible way for it to survive. This doesn't occur that often, but that's not to say it doesn't occur at all.
In considering NBAC’s analytic approach, an otherwise competent person who is acutely ill might be considered at especially high risk of harm for situational cognitive vulnerability.
This type of vulnerability refers to the person who is otherwise doing a great job, but is currently in a bad situation that is preventing them from demonstrating their full capacity. This is why they are at a risk of suffering from this.
