motility

Motility refers to the ability of cells or organisms to move or to how certain parts of the body, like the digestive organs or sperm cells, move. In the context of the digestive system, motility involves the contractions of muscles in the stomach and intestines that help mix food and push it through the digestive tract. For sperm, motility describes their capacity to swim toward an egg for fertilization. Essentially, motility is about movement—important for processes like digestion, reproduction, and even how bacteria and other microorganisms function.
