SYSTEMS OF THE BODY
BODIES…The Exhibition provides an intimate and informative view into the human body.
Like the frame of a house, the skeleton forms the internal structure of the body. It resists the pull of gravity and protects vital organs, while over 100 joints provide it with remarkable mobility. All bones store important mineral salts; in addition, red bone marrow in the flat and long bones creates 2.5 million new red blood cells each second.
The muscular system is the engine that drives the body. By connecting across the joints of the skeleton, muscles create levers that, when they contract, move the bones. Other types of muscles move food through the digestive tract, blood through the blood vessels and keep the heart beating every second of your life. Like any good engine, the muscular system also produces heat, which helps maintain body temperature.
Faster than the world's most powerful computer, the nervous system transmits information through nerve cells at speeds above 270 miles per hour. As the main organ of the nervous system, the brain determines the appropriate response to thousands of pieces of information each second, while also maintaining all vital body functions as well as processing thoughts and emotions.
The surface area of the lungs is great enough that, if spread out, it would cover half a football field. The body requires a constant supply of oxygen for life. The respiratory system provides oxygen by drawing air into the lungs and supplying oxygen to the bloodstream through the diffusion of gasses. While oxygen passes into the bloodstream, carbon dioxide – a waste product made by every cell in the body – passes into the lungs and is exhaled at the end of each breath.
One of the world's most efficient dis-assembly lines, the digestive system uses a combination of mechanical and chemical processes to break down the food we eat and convert it into nutrients that the body can use for food.
The complex filtration within the kidneys requires over 100 miles of blood vessels. Through a process of continual and complex filtration, the urinary system collects metabolic waste products from the blood and removes them from the body while maintaining the proper balance of water and electrolytes in the blood.
REPRODUCTIVE SYSTEM AND FETAL DEVELOPMENT
While every other cell in the body has 46 chromosomes, the female sex cell, the egg, and the male sex cell, the sperm, have only 23. Only when the egg and sperm combine is a new cell created that is capable of developing into a human.
Crisscrossing the body in a fine weave, the blood vessels of the circulatory system hold the body together. They transport everything the cell needs to maintain life. The circulatory system carries oxygen and nutrients throughout the body, as well as powerful guardian cells that seek out and destroy any virus or bacteria.
THE TREATED BODY
Thanks to medical research, we are living longer and staying healthier. Advanced diagnostic equipment, like Magnetic Resonance Imaging (MRI), has greatly assisted in diagnosing and pinpointing disease, making surgery more accurate and efficient. Thorough study of human anatomy, through educational vehicles such as the specimens in Bodies Revealed, has also enabled the development of prosthetic replacements for many parts of the body. Additionally, such detailed study has yielded specialized tools that help surgeons gain access to and monitor regions of the body in the operating room.
