Brain

• The brain stores information, allows you to think and learn and controls vital daily functions (such as digestion, heart rate and breathing).

• The brain receives impulses from nerves, which are located throughout the body, and responds to pain and other stimulation.

• Even though the brain is so important, it is also very delicate. The brain is made of soft tissue and is protected only by the skull, therefore head injuries can be serious.

Heart

• The heart is another vital organ. In an average lifetime, the heart beats more than 2.5 million times.

• The heart's job is to pump oxygenated blood throughout the body and receive deoxygenated blood in return.

Kidneys

• The kidneys are located under the rib cage in the lower back.

• The kidneys filter things, such as water and salts, out of the blood and produce urine.

• The kidneys also produce an enzyme called rennin. This enzyme plays a big role in regulating blood pressure.

Liver

• The liver is in the upper abdomen, slightly to the left.

• The main job of the liver is to produce bile, which it sends to the stomach for digestion.

• The liver also filters out toxins and regulates blood sugar.

• Blood sugar is regulated by the liver, which converts and stores sugar and releases it as needed into the bloodstream.

• The liver is also in charge of releasing cholesterol, breaking down fats and producing blood proteins. It is the largest internal organ.

Pancreas

• The pancreas is located behind the stomach.

• The job of the pancreas is to produce enzymes necessary for digestion and send them to the stomach.

• The pancreas also regulates blood sugar by producing insulin.

• The pancreas also creates glucagon that has the opposite effect of insulin and helps to maintain blood sugar levels.

Stomach

• The stomach receives food from the esophagus and sends it into the small intestine.

• The stomach's role in digestion is to break down food and mix it with digestive enzymes.

Small intestine

• The job of the small intestine is to digest food.

• It does this by using chemicals, such as enzymes.

• The small intestine also absorbs nutrients and transfers them to the blood.

• The small intestine is five meters long. The food moves from the small intestine to the large intestine with a series of muscle contractions.

Large intestine

• The large intestine is located in the abdomen and is 1.5 meters in length.

• The large intestine is involved in digestion. It receives undigested food from the small intestine.

• The large intestine absorbs as much water as possible from the food and then expels the waste and any excess fiber.

Lungs

• The lungs are located in the chest and are protected by the rib cage.

• The lungs take in oxygen and they expel carbon dioxide. The lungs deliver oxygenated blood to the heart where it is pumped throughout the body and they receive deoxygenated blood from the heart after blood travels throughout the body.
