Answer: D) precapillary sphincters relax.
Explanation:
Blood flow to a tissue will decrease if precapillary sphincters relax as, capillaries provides glucose and oxygen to the cells and allows blood to flow through it when the muscle ring known as the precapillary Sphincters get relaxed. The blood flow is stopped when the precapillary sphincters constrict flow of blood. As, certain chemical signals causes feeder arterioles to dilate and bring more blood into local areas then, it causes precapillary sphincters to relax.
There are two possible causes of metabolic alkalosis such as ,firstly loss of stomach acids which is most common cause of metabolic alkalosis ,secondly reduced volume of blood in the arteries.
Metabolic alkaloiss is developed by body when it loses too much acid or gains too much base then excess vomiting which causes electrolyte loss, adrenal disease ,loss of potassium or sodium in a short amount of time.
Concomitant NH4+ losses in the diarrhea fluid may also contribute to development of metabolic alkalosis when hyperchloremic acidosis caused by the loss of too much sodium bicarbonate from the body which can happen with severe diarrhea.

The living will is a document whose precise purpose is to allow individuals to record specific instructions about the type of healthcare they would like to receive in particular end-of-life situations.
An advance directive, commonly referred to as a living will, is a legal instrument that describes the kind of medical care a person wants or does not want in the event that they are unable to express their preferences verbally. Doctors and hospitals refer to the living will when a patient is asleep and has a terminal illness or a life-threatening accident to determine whether the patient wants life-sustaining treatment, such as aided breathing or tube feeding. In the absence of a living will, the spouse, family members, or other third parties are in charge of making decisions on medical treatment.
