How the Body Works for Kids
(scroll this section to read all)



Your body works in an extremely complicated but amazingly efficient way. If you have ever wondered about how the main systems in your body work you have come to the right place. Just read our information and use our fantastic resources to learn more including games which improve your knowledge! Also see our Science Article 'ANIMALS INCLUDING HUMANS'.

Skeleton

The human skeletal system is made up of >200 bones in adults and its function is to give your body shape and enable movement. The major bones are the Skull, Cervical vertebrae, clavical, sternum, humerus, spine (made up of vertebrae), ribs, radius, ulna, pelvis, femur, patella, tibia, fibula and the phalanges. If you are taking part in any sports where bones could be broken, wear the correct protective equipment e.g. shin pads if you are playing soccer. To maintain healthy bones eat lots of calcium present in dairy products such as milk. Regular activity strengthens bones too.

Muscles

Muscles perform a number of functions including maintaining body posture, providing movement, stabilizing joints and maintaining a stable body temperature. There are more than 600 muscles spilt up into 3 categories.

  • Smooth (involuntary) muscles e.g. digestive
  • Cardiac muscles (involuntary) e.g. heart muscles
  • Skeletal muscles (controllable). These are muscle that we typically think of as muscles (biceps, triceps, quads etc.)

To maintain healthy muscles perform lots of exercise and provide proper, healthy nutrition and hydration. Also gets lots of rest and control stress levels.

Nerves

The Nervous system consists of the brain, spinal cord and the nerves themselves. The brain manages the complete functioning of the body by controlling the nerves which in turn control the local body parts. The major parts of brain are the cerebrum (thinking part of brain), cerebellum (for movement, balance and coordination) and the thalamus (takes sensory data like touch, feel, smell to the brain) and the brain stem which connects to spinal cord. The spinal cord links the nerves to the brain so signals can be passed either way to the brain which is the master controller! Always protect the head when there is a higher risk of knocking it (wear a cycle helmet when cycling for example). Maintain a healthy brain by eating healthy foods (especially those containing potassium and calcium), taking regular exercise and stimulating the brain by challenging it to remain active (for example by doing puzzles, crosswords, quizzes etc.).

Immune System

The body's defense system is called the immune system and is made up from cells and organs. The main components include blood vessels, bone marrow, lymph nodes, adenoids, appendix, lymphatic vessels, peyer's patches, spleen, thymus and the tonsils. The immune system's job is to protect the body from infection by keeping out and fighting infected micro-organisms. Lymphoid organs produce lymphocides which are the body's method of fighting infections. To maintain a healthy immune system you should control stress, get proper sleep, eat a healthy diet and get plenty of exercise.

Endocrine system

The endrocine system is a collection of glands that produce hormones to grow and develop your body. Each gland has its own specific function. The main glands are the pineal, pituitary, hypothalamus (controls hunger), thyroid, parathyroids and the adrenals. To maintain a healthy endrocine system you should eat a good nutritious diet, take plenty of exercise, enjoy good sleep and control your stress levels.

Cardiovascular system

This consists of the heart and blood vessels. The heart contains 4 valves and is separated into 4 sections to separate incoming from outgoing blood. The heart pumps blood to other body parts via the blood vessels to provide much needed oxygen to all the functioning parts of your body. Maintain a healthy heart with lots of exercise, good nutritious food and , of course, no smoking or excess alcohol.

Respiration

The respiratory system consists of organs that help you to breathe so you can deliver oxygen into the body for the blood to transport around and also to remove the expired air containing, for example, higher levels of poisonous carbon dioxide. The respiratory system consists of the trachea, lungs and the diaphragm. When you breathe in the diaphragm contracts allowing oxygen rich air from the nose or mouth into the lungs and when the diaphragm expands the lungs are forced to expire carbon dioxide in the opposite direction. Maintain a healthy respiratory system by avoiding smoking and having copious amounts of exercise.

Digestive system

The digestive system converts the food we eat into energy in order to keep our body going. The whole digestive system consists of the mouth, esophagus, liver, stomach, gall bladder, pancreas, intestines and the rectum. It is the digestive systems job to make sure all solid waste products are separated and passed through to the rectum where it is disposed on via poop. Maintain a healthy digestive system by drinking lots of water and eating lots of healthy fruit and vegetables and avoid too much greasy or fatty foods which are difficult to digest.

Urinary system

The urinary system gets rid of waste and excess fluid from the body and comprises the kidneys, ureters, bladder and urethra. The kidneys clean the blood and remove waste producing urine. The urine exits the body after being sent via the ureters to the bladder. When the bladder is approximately 50% full you will get a bodily sensation that you need to empty your bladder by going to the toilet. To maintain a healthy urinary system, do lots of exercise, drink water, avoid smoking or excess alcohol and eat a healthy and nutritious diet.
