The main concern of anatomy is to recognize the relationships, the
connections between the individual components within the human body.
Medical professionals often refer to sections of the body in terms of
anatomical planes (flat surfaces). These planes are imaginary lines –
vertical or horizontal – drawn through an upright body. The terms are used
to describe a specific body part. |

The cardiovascular system is made up of the heart and all of the blood and lymphatic vessels in the body. The heart acts as a pump to drive the blood; a complex fluid made up of digested food materials, respiratory gasses (oxygen being carried in, carbon dioxide being carried out), and protective and regulatory chemicals through the approximately 60,000 miles of vessels in the body. |

The digestive tract, one of the largest of all body systems, extends
approximately 30 feet long and extends as a long continuous tube, from
mouth to anus! This system is unique in that it is strictly speaking
"outside the body". That is, it's long continuous tube communicates with
the outside world. The digestive system is 2nd in importance in terms of
function to the master controlling system, the nervous system. These
articles explain why. |

If asked how we would like to die, many of us would reply "from old age."
Instead of suffering disease prior to death, we would like to remain
reasonably healthy until one day our body stops working, preferably in our
sleep. But does anyone really die of old age, or is there always an
underlying disease? |

The endocrine system carries out a wide variety of physiological processes
through chemical messengers called "hormones." This system is a collection
of glands that produces these hormones, which are necessary for normal
bodily functions. |

The urinary tract is a little like a plumbing system, with special pipes
that allow water and salts to flow through them.
The structure of the urinary tract includes: the kidneys, two ureters,
(tubes leading from the kidneys to the bladder), and the urethra, a tube
leading from the bladder to the exterior of the body. |

Cells are the smallest structures capable of basic life processes, such as
taking in nutrients, expelling waste, and reproducing.
The cell is a marvel of design and efficiency. Cells carry out thousands
of biochemical reactions each minute and reproduce new cells that
perpetuate life. We give you the details. |

The immune system is a complex network of specialized cells and organs
that has evolved to defend the body against attacks by "foreign" invaders.
When functioning properly it fights off infections by agents such as
bacteria, viruses, fungi, and parasites. When it malfunctions, however, it
can unleash a torrent of diseases, from allergy to arthritis to cancer to
AIDS. |

Although, we've included the mind as part of the body, you'll see it isn't
part of the body but it can control the body. What has been a very
confusing subject is clarified it this series of articles.
How does your mind affect your body? or your behavior? And does it really
contain the commands that kick in and control the way you think, act and
feel without you knowing it? |

The human musculoskeletal system provides locomotion, support and
protection to the human body.
This system consists of osteology (the study of bones), arthrology (the
study of joints), and myology (the study of muscles).
We cover your major locomotion system in detail. |

The nervous system of the human being is responsible for sending,
receiving, and processing nerve impulses throughout the body. All the
organs and muscles inside your body rely upon these nerve impulses to
function. It could be considered as the master control unit inside your
body. |

The respiratory system for gaseous interchange, which consists of the
upper respiratory tract and the lower respiratory tract. Respiration is
carried on by the expansion and contraction of the lungs; the process and
the rate at which it proceeds are controlled by a nervous center in the
brain.
We cover the respiratory system with these articles. |

The special senses consist of the eyes, ears, nose, throat and skin. Each
of these organs have specialized functions that make if possible for us to
experience our environment and to make that experience more pleasant.
We give you detailed information regarding each of these organ. |

Once you've completed your study of the human body, why not test your
knowledge?
Our testing modules test your knowledge of every organ
system you've received in this package. These tests are a great way to know if you've
really absorbed the information regarding each corresponding body system.
The added benefit is that you can retake any test as many
times needed, until you've passed the test. |
