NERVOUS SYSTEM Our first stop, the Nervous System, stay away from headaches; this is the most complex system in the body. This system is broken down into two parts, the Central Nervous System and the Peripheral Nervous System. Their main job is to get information from the body and send out instructions.

RESPIRATORY SYSTEM Lungs provide the breath of life. The lungs are protected by our ribs, they are the pickup place for oxygen and the drop off place for carbon dioxide. Blood with oxygen leaves the lungs through the pulmonary veins and travels to the heart. Oxygen is the fuel that makes all the body processes run.

EXCRETORY SYSTEM The excretory system is the body system that separates and gives off the waste from the body, usually as urine or sweat. § Skin excretes extra salts, water, and heat. § Lungs excrete carbon dioxide from the body. § The liver changes the ammonia, a poisonous product of protein digestion, into urine.

MUSCULAR SYSTEM Welcome to the muscles. Muscles are responsible for your body's every move. Muscles keep your gut from sagging and your lungs pounding. Muscles are more than movers. Muscles make the heat that keep you warm. If you leap, bend, or reach, this is a result of a muscle action. A muscle makes itself smaller when it contracts and larger when it relaxes. Follow the lizards to find out about the three types of muscles and what they do in the body.

ENDOCRINE SYSTEM The endocrine system is one of the body’s main systems for communicating, controlling and coordinating the body’s work. It works with the nervous system, reproductive system, kidneys, gut, liver, pancreas and fat to help maintain and control the following: • body energy levels • reproduction • growth and development • internal balance of body systems, called homeostasis • responses to surroundings, stress and injury

IMMUNE SYSTEM You probably know that your heart pumps blood. You may even know that the kidneys filter the blood and create urine. But do you know what your spleen does? Did you know you have an organ called a thymus? These last two organs, along with lymph nodes, bone marrow, and other tissues are all important parts of the immune system. Bone Marrow - Bone marrow is a tissue that lies inside most of your bones. The thymus is a small, butterfly-shaped organ which lies between your breastplate and your heart. The spleen performs several functions; it filters the blood, destroying old or damaged blood vessels. Lymph nodes are a bit like the spleen, but instead of filtering blood they filter lymph. Lymph is composed of fluids which drain from tissues.

INTEGUMENTARY SYSTEM The body's integumentary system supports the excretory system in the removal of waste. Skin, hair, fingernails and toenails make up the system by which surface level wastes are removed. The skin protects the body and also provides for the removal of dead cells and sweat, which contains waste products. Hair, fingernails and toenails are actually accumulations of dead epidermal cells. As more cells die and need to be removed,

DIGESTIVE SYSTEM The human body needs fuel to live. We eat food for fuel. But just getting the food into the body is only a small part of the process. The food must be broken down into chemicals that the body can use. This whole process is called digestion. Some of the organs involved in digestion are the mouth, esophagus, stomach, small and large intestines, gallbladder, pancreas and liver. Follow the lizards to find out how the body uses the food we eat.

SKELETAL SYSTEM Welcome! This is the skeletal system, we need our skeletal system for many reasons, one of which is to survive. The skeletal system is what keeps your body in shape, protects your vital organs, such as the heart, brain, and lungs, and enables you to move.

CIRCULATORY SYSTEM The Circulatory System, where everything starts and ends with the heart, where you’ll have the ride of your life in our famous “Circulator” Roller Coaster. As we begin to circulate, we’ll exit the heart from the left ventricle into the aorta, don’t be afraid to move around, the aorta is the largest artery in the body. We’re now leaving the aorta where the blood your being splashed with is full of oxygen, I hope you brought your raincoats. As we slide down through the arteries into the smallest arterioles, don’t be afraid of the person next to you, it gets personal as you enter the arterioles. Arterioles are very small so you might end up with your face under someone's underarm (hope they put on deodorant). Sadly, it ends here as we travel back to the heart through our system of veins, we reach the lungs where all the carbon dioxide we traveled back with is than exchanged with fresh oxygen where it is sent back out throughout the body.

REPRODUCTIVE SYSTEM All living things reproduce. Reproduction — the process by which organisms make more organisms like themselves — is one of the things that sets living things apart from nonliving matter. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes, are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system to create a new individual.
