body cavity

fluid filled spaces that protect and holds internal organs

dorsal cavity

protects organs of nervous system, 2 major subdivisions are cranial and vertebral (spine) (back side)

ventral cavity

more anterior ,houses internal organs, major 2 divisions are separated by diaphragm (front side)

cranial cavity

brain

spinal cavity

spinal cord

abdomen

stomach area

pelvic

diaphragm

separates thoracic & pelvic region

thoracic cavity
