The correct answer is A. Work together to perform functions. Our body's organ systems are specialized groups of organs that work together to perform specific functions necessary for the overall functioning of the body. Each organ system has its own set of organs, tissues, and cells that work in coordination with other organ systems to maintain homeostasis and carry out vital functions such as circulation, respiration, digestion, and locomotion. It is the collective effort of all the organ systems that enable our bodies to function properly.
