Answer:
The best response to the question: Brain blood flow autoregulation:___, would be, B: causes constriction of cerebral blood vessels in response to a drop in systemic blood pressure.
Explanation:
The maintenance of blood pressure for the brain is vital. This organ alone consumes around 20% of the total amount of oxygen available in the body, and whenever conditions change for the worse, the brain will generate actions to ensure that its blood flow is maintained. To do this, the brain has the capacity for autoregulation, meaning, the organ itself has the means to control the process, even if the rest of the body cannot. To do this, the brain resorts to several different mechanisms, and as of today, scientific research cannot assure that one mechanism is primary over others. What it is known for sure is that changes in systemic pressure drive the brain to initiate mechanisms of autoregulation to ensure that the flow, and pressure for nutrition and gas exchange in the brain, will be maintained. That is why the answer is B.
A bag valve mask (BVM), sometimes known by the proprietary name Ambu bag or generically as a manual resuscitator or "<em>self-inflating bag</em>", is a hand-held device commonly used to provide positive pressure ventilation to patients who are not breathing or not breathing adequately.
