  2. What are organ systems? • Organ systems • An organ system is made from a group of different organs, which all work together to do a particular job. Here are some examples of organ systems: • circulatory system • respiratory system • digestive system • nervous system • reproductive system • leaf canopy

  3. Circulatory Organ. • This organ system is made up blood, blood vessels and the heart. • It circulates blood to deliver oxygen and nutrients to every part of the body.

  4. Digestive system. • The purpose of the digestive system is to turn the food you eat into something useful for the body. When you eat, your body uses this system to digest food so your cells can use it to make energy. The organs involved in this system include the mouth, stomach, and intestines. Pancreas and salivary glands Produce digestive juices • The stomach digests food • The liver produces bile • The small intestine digests and absorbs soluble food • The large intestine absorbs water from undigested food, producing faeces.

  5. The nervous system • The nervous system is the control center of the human body. It is made up of the brain, spinal cord, and nerves. It receives and interprets stimuli and transmits impulses to organs. Your brain uses the information it receives to coordinate all of your actions and reactions. • the brain is made up of three major parts: the cerebrum which controls thinking and memory, the cerebellum which controls balance and coordination and the medulla oblongata which controls involuntary actions such as heartbeat, breathing and digestion • The major large set of nerves running down the spine and protected by the spinal column or vertebrae

  6. Muscular System • This system is made up of muscle tissue that helps move the body and move materials through the body. Quite simply, muscles move you. Muscles are bundles of cells and fibers that work in a simple way: they tighten up and relax • There are three different kinds of muscle: voluntary, involuntary, and cardiac. Cardiac muscles are located in the heart, and they are a form of involuntary muscle. These muscles keep the heart beating, ensuring the blood is pumped through the body. They are controlled by the autonomic nervous system.
