environment and sends them to the
brain
Body System
urinary system
kidneys, ureters, bladder, urethra
- produces urine and sends it out of the
body
Body Cavity
cranial cavity
contains the brain and other organs (glands)
Body Cavity
thoracic cavity
chest cavity, surrounded by the breastbone and ribs
- lungs are each surrounded by a
double membrane known as the pleura
- space between the pleural membranes is the
pleural cavity
- large area between the lungs is the mediastinum
Body Cavity
abdominal cavity
space below the thoracic cavity - diaphragm is the muscle that separates the abdominal and thoracic cavities - organs in the abdomen are covered by a double membrane called the peritoneum
Body Cavity
pelvic cavity
below the abdominal cavity
- surrounded by the pelvis
Body Cavity
spinal cavity
space surrounded by the spinal column
- spinal cord is the nervous tissue within the spinal cavity
