👉 The retreat fluid, also known as the retractile or retractor fluid, is a specialized fluid found in certain animal tissues, particularly in muscles and connective tissues, that plays a crucial role in facilitating movement and tissue repair. It is secreted by specialized cells called retractors, which are embedded within the extracellular matrix. When these retractors contract, they generate a pressure that helps pull tissues together or separate them, enabling actions such as muscle contraction and relaxation, wound healing, and the movement of organs. This fluid is essential for maintaining tissue integrity and function, allowing for smooth and controlled movements while also supporting the body's repair processes after injuries.
