Is transporting cells that attack disease-causing microorganisms a function of the cardiovascular system?

The statement is False.

The cardiovascular system, composed of the heart, blood vessels, and blood, has specific functions unrelated to transporting cells that attack disease-causing microorganisms. Its primary function is to pump oxygenated blood throughout the body, deliver nutrients to tissues, and remove waste products such as carbon dioxide. The specific transportation of immune cells involved in pathogen attacks is a function of the lymphatic system.
