What does motility refer to in the context of cells?

Motility, in the context of cells, refers specifically to the ability of cells to move actively and carry out directed movement. This movement is crucial for various biological processes, including immune responses, wound healing, and the movement of certain types of cells through the circulatory system, such as white blood cells or cancer cells. In this sense, motility encompasses the movement of cells through fluids like blood or lymph, which is essential for their functions in the body.

This definition aligns well with the chosen answer, which highlights the significance of movement through lymph or blood. Understanding cell motility is important in fields such as pathology and immunology, as it helps explain how cells interact with their environment and contribute to various physiological and pathological processes.
