A Human Body

 BODY:     

• The Human Body consists of a number of interacting 'systems'. The skeleton forms a rigid framework, which, attached to the muscles, facilities movement initiated by the nervous system- responsible for the body's reaction stimuli.

• Hormones, produced by the endocrine system, control many functions, including growth and developmental changes such as puberty.

• The cardio-vascular system circulates blood around the body, delivering oxygen and nutrients and collecting carbon dioxide and waste.

• The respiratory system exchanges carbon dioxide for inhaled oxygen.

• The digestive system derives energy and nutrients for growth and repair from food.

• The urinary system eliminates waste; the urinsry system also helps to regulate chemicals in the body.

• The reproductive system is concerned with producing offspring.
