Introduction: Some terms used to describe the relative positions of body parts are used. ISBN , Introduction and Terminology. These systems are closely interrelated and interdependent. See image of free textbook below.
The human body is actually an amazing coalition of many different systems that work together to keep everything functioning correctly. For example, some systems handle food and energy, while others focus on taking in oxygen and moving it around the body. By learning about the different systems working inside the body, you can understand how everything works together to keep you healthy, growing, and strong. Your brain and spinal cord are the major parts of the central nervous system. Different parts of your body send messages to the brain through the nerves and spinal cord.
You have probably heard this Billy Ray Cyrus song. Heartache, heartbreak Did you ever wonder why the heart is associated with love? The heart was once thought to be the center of all thought processes, as well as the site of all emotions. This notion may have stemmed from very early anatomical dissections that found many nerves can be traced to the region of the heart. The fact that the heart may start racing when one is excited or otherwise emotionally aroused may have contributed to this idea as well.
Younger primary students may have little knowledge about internal bodily organs. They tend to think the contents of the body are what they have seen being put into or coming out of it, such as food and blood. Their experiences with everyday cuts, scratches and bruises seem to reinforce a view that blood is below the surface of the skin, filling the spaces inside the body like a bag of blood. Older children are more likely to be able to list a large number of organs but may not fully understand the function or interconnected nature of these. For example, students at these levels may realise that the heart is a pump but not realise that the blood returns to the heart, or they may believe that the brain helps the body parts but not always realise that the body helps the brain. To survive and reproduce, the human body relies on major internal body organs to perform certain vital functions. When two or more organs along with their associated structures work together they become component parts of a body system.
Different organs can work together to perform a common function, like how the parts of your digestive system break down food. We refer to an integrated unit as an organ system. Groups of organ systems work together to make complete, functional organisms, like us!
Люди на подиуме с недоумением переглянулись. Дэвид подмигнул крошечной Сьюзан на своем мониторе. - Шестьдесят четыре буквы. Юлий Цезарь всегда с нами.

- Добрый вечер, мистер Хейл. - Он нахмурился, глаза его сузились. - Сегодня суббота. Чем мы обязаны. Хейл невинно улыбнулся: - Просто хотел убедиться, что ноги меня еще носят.
