Which type of embalming solution is used to remove excess moisture?

The use of a hypertonic embalming solution is instrumental in removing excess moisture from the body's tissues. Hypertonic solutions contain a higher concentration of solutes compared to the body's cells. When these solutions are introduced into the tissues, they create an osmotic gradient that draws moisture out of the cells and interstitial spaces. This process effectively reduces moisture retention, which is critical during the embalming process to ensure proper preservation and to prevent potential decomposition.

In contrast, hypotonic solutions would result in the movement of water into the cells, potentially leading to cell swelling and rupture, which is counterproductive in embalming. Isotonic solutions maintain the balance of solute concentrations inside and outside the cells, thus not facilitating moisture removal. Hypotonic/humectants typically refer to solutions designed to retain moisture rather than to draw it out, making them unsuitable for the goal of excess moisture removal. Therefore, the correct choice reflects the function of hypertonic solutions in the context of embalming practice.
