This organ system breaks down food into nutrients that the body can absorb.

Digestive System

200

This plane cuts the body into left and right halves.

Sagittal 

200

Going towards the back of the body.

Posterior

300

This organ system is responsible for producing and secreting hormones for body regulation.

Endocrine System

300

This plane cuts the body into superior and inferior halves.

Transverse Plane

300

Going towards the midline.

Medial 

300

Lines ventral body cavities that are closed, as well as covering many organs

Serous Membrane

300

This portion of the ventral cavity contains the small and large intestine. 

Abdominal Cavity

400

This organ system provides protection from the outside environment and contains the larges organ in your entire body.

400

This plane cuts the body into anterior and posterior halves.

Frontal/Coronal Plane

400

Going towards the direction where a limb attaches to the trunk.

Proximal

400

The membrane that covers the brain and spinal cord in the dorsal body cavity.

Meninges

400

This portion of the dorsal cavity includes the spinal chord. 

Vertebral Cavity

500

This organ system provides both gas exchange and the transport of nutrients.

Cardiovascular System.

500

This variation of the sagittal plane cuts off the midline.  

Parasagittal Plane

500

Going away from the external surface of the body.

Deep.

500

This type of serous membrane coats your internal organs.
