A person with diarrhoea loses excessive salt and water from the body. This loss results in Na⁺ depletion, dehydration, a decreased extracellular fluid volume, a reduction in plasma volume, and a decreased systemic arterial blood pressure.The following refer to the events that occur to compensate for this fluid loss. Match the effects, labelled a. through c., with the factors listed. (Options may be used more than once or not at all.)
-vasopressin secretion
A)exhibits no change
B)is increased
C)is decreased

Question

Quizplus · Accepted Answer

The excessive loss of water triggers the release of vasopressin (also known as antidiuretic hormone, or ADH) from the pituitary gland. Vasopressin acts on the kidneys to increase water reabsorption and decrease the production of urine. Therefore, to compensate for the fluid loss in diarrhoea, the secretion of vasopressin is increased.
