skin, and nails. The skeletal system protects and supports body organs and provides a framework the muscles use to cause movement. The muscular system allows manipulation of the environment, locomotion, facial expression, maintains posture, and produces heat. The endocrine system has glands that secrete hormones that regulate processes such as growth, reproduction, and nutrients used by body cells. Cardiovascular system has blood vessels that transport blood, which carries oxygen, carbon dioxide, nutrients, wastes, etc. and the heart pumps blood throughout the entire body. The lymphatic system picks up fluid leaked from blood vessels and returns it to blood. It also disposes of debris in the lymphatic stream and houses white blood cells involved in immunity. The respiratory system keeps blood constantly supplied with oxygen and removes carbon dioxide. The digestive system breaks down food into absorbable units that enter the blood for distribution to blood cells. The urinary system eliminates nitrogenous wastes from the body. Lastly, the reproductive system is the only organ system you could live without because its overall function is the production of offspring. The eleven interacting systems each contribute to the maintenance of homeostasis, of itself, other organ systems and of the entire body.
