The article, The Body Shop is about how Dr. Gail Naughton documented a container called a bioreactor that balances conditions inside of a healthy body. It also puts stress on cells as they grow. Dr. Naughton came to the results that material grown in the reactor have twice as much strength as proteins, elastin, collagen, and things that are grown in a petri dish. The growth of blood vessels is very strong when it is grown in a bioreactor. NASA scientists have learned an important lesson about tissue growth in which it cultivates cells in weightlessness space. Studies have shown that tissues that form sheets like skin or cartilage have better under forces. So, NASA researches have developed their own biorector that keeps the cells that are growing in perpetual free fall. Liver tissues develop more naturally in microgravity, it which it forms spherical clusters of functioning liver cells according to Naughton. Complex organs like the heart, kidney, and liver are complex because it requires a highly vascularized organ that is right down to its capillaries. Naughton said that tissue engineering will change transplant medicine. Naughton and her colleagues at Advanced Tissue are working on a project that will stimulate vessel growth around and in diseased hearts. Hopefully, one day they can treat a disease early on so someone doesn't have to have a new heart. In conclusion, the bioreactor is a great tool that maintains alot of tissues inside of your body.

Organization of the Body
The Directional Terms on your body consists of Superior and Inferior, Anterior and Posterior, Medial Lateral and Intermediate, Proximal and Distal, Superficial and Deep.
Superior~ The upper part of your body.
Inferior~ The lower part of your body.
Anterior~ In front of your body.
Posterior~ Behind your body.
Medial~ The midline of your body.
Lateral~ The outer side of your body.
Intermediate~ Between a medial and a more lateral structure.
Proximal~ Close to the origin of the body part, the point of attachment
of a limb to the body part.
Distal~ Farther away from the origin of the body part.
Superficial~ At the body surface.
Deep~ Away from the body surface.
Body Planes:
Sagittal~ It divides your body into right and left parts.
Midsagittal~ This is the saggital plane that is on the midline.
Frontal or Coronal~ Divides your body into anterior and posterior parts.
Transverse or Horizontal~ Divides your body into superior and inferior parts.
Oblique section~ Cuts are made diagonally.
Body Cavities:
The Dorsal cavity protects the nervous system, and it is spit into two subdivisions.
Cranial cavity~ This is located in your skull, and it encloses your brain.
Vertebral cavity~ This runs through the vertebral column, and it encloses the spinal cord.
Ventral cavity~ It is divided into two subdivisions which are the thoracic and abdominopelvic.
Thoracic cavity~ Split into pleural cavities which are the mediastinum, and the pericardial cavity.
Pleural cavities~ They each surround a lung.
Mediastinum~ This contains the pericardial cavity, and it surrounds the area of the remaining thoracic organs.
Pericardial cavity~ Bounds the heart.
The abdominopelvic cavity is separated from the superior thoracic cavity, and it is composed of two subdivisions.
Abdominal cavity~ This contains your stomach, intestines, liver, spleen, and many other organs.
Pelvic cavity~ This lies within the pelvis and it contains your bladder, rectum, and reproductive organs.
Other Body Cavities:
Oral and Digestive~ These are the mouth and cavities of the digestive organs.
Nasal~ This is located posterior to your nose.
Orbital~ This surrounds your eyes.
Middle Ear~ Contains bones that passes sound vibrations.
Synovial~ These are your joint cavities.
Superior~ The upper part of your body.
Inferior~ The lower part of your body.
Anterior~ In front of your body.
Posterior~ Behind your body.
Medial~ The midline of your body.
Lateral~ The outer side of your body.
Intermediate~ Between a medial and a more lateral structure.
Proximal~ Close to the origin of the body part, the point of attachment
of a limb to the body part.
Distal~ Farther away from the origin of the body part.
Superficial~ At the body surface.
Deep~ Away from the body surface.
