Integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive, and digestive are the 11 organ systems of the body. Although each of your 11 organ systems serves a distinct purpose, each organ system is also dependent on the others, either directly or indirectly. For example, your skin is a direct extension of your immune system. Whenever bacteria, viruses, or other foreign particles enter your body, they first encounter one of your 11 major organ systems. If they make it past that first line of defense and into your bloodstream, then they have reached one of your many blood cells.
