THE STRUCTURE OF THE BODY
The body consists of many parts, all with different functions. The proper functioning of
the body depends on the different parts working together.
The human body consists of millions of tiny cells of different shapes and sizes each
performing a different function. Cells of the same size and function join to form tissue. Two or
more types of tissue join to form organs. Organs work with other organs to form systems and
systems work together to perform the various functions of the body.

THE SYSTEMS OF THE BODY
There are ten systems in the Human Body.
1. THE SKELETAL SYSTEM
Bones, joints. Provides a rigid framework which supports the body.
2. THE MUSCULAR SYSTEM
Muscles, tendons. Moves limbs and drives blood around the body.
3. THE SKIN SYSTEM
Skin, nails, hair. Provides a barrier that protects the body and control temperature.
4. THE NERVOUS SYSTEM
Brain, spinal cord, nerves. The body’s control centre and communication system.
5. THE RESPIRATORY SYSTEM
Nose, windpipe, lungs. Takes in oxygen and removes carbon dioxide and waste.
6. THE CIRCULATORY SYSTEM
Blood vessels, heart, blood. Transports blood to cells, removes waste and help fight
disease.
7. THE DIGESTIVE SYSTEM
Mouth, oesophagus, stomach, intestines, glands. Breaks down food for use inside of the
body.
8. EXCRETTORY (URINARY) SYSTEM
Kidneys, bladder. Removes waste products as urine.
9. ENDOCRINE SYSTEM
Pituitary gland, Thyroid gland, Pancreas, etc. Glands producing hormones that regulate a
number of body functions.
10. REPRODUCTIVE SYSTEM
Sexual organs, Ovaries and uterus in women. Reproduces
