Question

Quizplus · Accepted Answer

Hypotonicity refers to a condition where there is a lower concentration of solutes outside the cells compared to inside the cells. This creates a gradient where water moves from an area of higher concentration outside the cells to an area of lower concentration inside the cells by osmosis. As a result, water enters the cells, causing them to swell and potentially rupture. Hypotonicity can be caused by various factors, including excessive sweating or diarrhea, kidney disease, or certain medications, and it can lead to serious health problems if left untreated. Drinking excess fluid is just one possible cause among many others. Conversely, hypotonicity is associated with a positive water balance, where the intake of water exceeds the output. Diabetes insipidus, not diabetes mellitus, is a condition characterized by a deficiency of vasopressin, a hormone that regulates water balance, and it can cause hypotonicity among other symptoms.
