What term describes the movement of arterial solution from capillaries into the surrounding intercellular spaces?

The correct term that describes the movement of arterial solution from capillaries into the surrounding intercellular spaces is diffusion. Diffusion refers to the natural movement of molecules from an area of higher concentration to an area of lower concentration until equilibrium is reached. In the context of arterial solution during the embalming process, the solution moves through the walls of capillaries and into the interstitial spaces where it can interact with the surrounding tissues.

Understanding diffusion is crucial in the embalming process, as it helps to determine how effectively the embalming solution penetrates tissue, contributing to the preservation and presentation of the body. The process ensures that the solution disperses adequately throughout the intercellular spaces, promoting thorough distribution of the chemicals needed for preservation.

In contrast, while osmosis relates to the movement of water across a semi-permeable membrane, absorption refers to the process by which substances are taken up by cells or tissues. Evaporation, on the other hand, involves the change of a substance from a liquid to a gas and does not apply in this context of fluid movement within interstitial spaces.
