Inside your body, there's a lot of teamwork going on! There are groups of organs and body parts inside of you that work together to help you breath, move and grow, among other things. Learn about the 11 organ systems of the body.

Organ Systems

If you had to pick the most important part of your body, what would you pick? Would you pick your heart or lungs? You can't live without them. But wait, your bones are important too! Without your bones, your body would collapse like a big pile of mush.

Your heart, lungs and bones are just a few of the parts that make up your organ systems. An organ system is a group of organs and body parts that work together to accomplish a common goal, like pumping blood and breathing. Let's look at the 11 organ system in your body.

Integumentary System

Did you know that your skin is an organ? Your integumentary (pronounced in-teg-you-men-tuh-ree) system is made up of your skin. This system essentially makes you waterproof, which is why you can soak in a tub without filling up with water. It also helps maintain body temperature and protect your insides.

Skeletal System

Your skeletal system includes your bones, which give you support so you can stand tall. They also protect deeper organs. For instance, your heart and lungs stay safe inside your rib cage. The inside of your bones is a softer area called marrow that makes blood cells.

Muscular System

Your muscles make up your muscular system. They attach to your bones and create movement when they contract, or shorten. You're able to walk around and pick things up because of your skeletal muscles, and you also have muscles that help other organ systems, like the cardiac and digestive systems.

Nervous System

Your nervous system is made up of your brain, spinal cord and nerves. It's the control system of your body. It monitors what's going on inside and outside your body, and it helps you respond correctly.

Endocrine System

Your endocrine system controls body functions using hormones, which are produced by endocrine glands. The hormones travel through your blood and affect things like growth, sleep and how nutrients are used.

Cardiovascular System

Your cardiovascular system is made up of your heart and blood vessels. Your blood vessels are like the highway of your body. When things like hormones, cells, oxygen and nutrients have to move around, they hitch a ride on your bloodstream.

Lymphatic System

Your lymphatic system plays a big role in immunity. Lymph nodes, your spleen and your tonsils are all parts of your lymphatic system, and they contain white blood cells that help fight infections.
