Answer:
Organ systems are groups of organs within the body that can be thought of as working together as a unit to carry out specific tasks or functions within the body. The human body is most commonly divided into eleven organ systems, the ones listed below.
It should be kept in mind that these divisions are somewhat arbitrary as to which organs are included and which are excluded. Skeletal muscles attached to bones are part of the muscular system, but the smooth muscles around soft tissues are not. Skeletal muscles are attached to bones, and serve to move the bones, but bones are part of the skeletal system, not the muscular system.
It also bears remembering that no one organ system ever functions independently of the others. The nervous system sends instructions to the muscular system as to when to move particular muscles. The cardiovascular system delivers nutrients and removes wastes from the muscle fibers of the muscular system to allow them to continue to function, etc. Dividing the human body into eleven organ systems is simply a way for the human mind to organize information about what parts do what. In the body itself, the parts that need to interact do interact, regardless of which system they have been grouped into.
The eleven organ systems are shown in Figure 1-10 and 1-11. The figure also lists the organs in each system and some roles for each system
