Description

The human body is an incredibly complex and amazing structure. At best, it is a source of strength, beauty, and wonder. We can compare the healthy body to a well-designed machine whose parts work smoothly together.We can also compare it to a symphony orchestra in which each instrument has a different part to play. When all of the musicians play together, they produce beautiful music. From a purely physical standpoint, our bodies are made mainly of water.We are also made of many minerals,including calcium, phosphorous, potassium, sulfur, sodium, chlorine, magnesium,and iron.In order of size,the elements of the body are organized into cells, tissues, and organs. Related organs are combined into systems, including the muscular skeletal, cardiovascular, nervous, respiratory, gastrointestinal, endocrine, and reproductive systems.
