Answer: Circulatory and respiratory
During running, the rate of breathing increases, because of increase in demand of oxygen by the body. The process of running affects the function of the lungs which is a part of the respiratory system. The heart is labored to pump out blood fastly, so as to transfer oxygenated blood all over the body. The heat energy is liberated in this process, which results in the release of sweat by the skin. The sweat gets evaporated by the external air, which keeps the body cool. Hence, circulatory and respiratory systems works together during running.

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.:)
