Front 1

Body Cavities

Back 1

internal chambers where vital organs are stored with two essential funcitons:
1. they protect delicate organs from accidental shocks, and cushion them from the thumps and bumps of movement
2. they permit significant changes in the size and shape of internal organs so activites of nearby organs are not disturbed.

Front 2

Ventral Body Cavity

Back 2

contains organs of respiratory, cardivascular, digestive, urinary, and reproductive systems

Front 3

Diaphragm

Back 3

a flat, muscular sheet that divides the ventral cavity into the superior thoratic cavity and inferior abdominopelvic cavity

Front 4

Thoratic Cavity

Bounded by the chest wall, upper cavity of the ventral body cavity, subdivided into right pleural cavity, mediastinum, and left pleural cavity and also contains the pericardial cavity

Front 5

Abdominopelvic Cavity

Back 5

enclosed by the abdominal wall and by the bones and muscles of the pelvis, lower portion of vantral body cavity divided into peritoneal cavity, and includes the abdominal cavity, and pelvic cavity

Front 6

Viscera

Back 6

internal organs that are partially or completely enclosed by these cavities

Front 7

Serous Membrane

Back 7

a delicate layer that lines the walls of these internal cavities and covers the surfaces of the enclosed viscera

Front 8

Visceral Layer

Back 8

a portion of serous membrane that covers a visceral organ

Front 9

Parietal Layer

Back 9

the opposing layer that lines the inner surface of the body wall or chamber

Front 10

Pleural cavities

Back 10

Subdivisions of the thoratic cavity that contain the lungs

subdivision of the thoratic cavity that contains the trachea, esophagus, and major vessels

Front 12

Pleura

Back 12

serous membrane that lines the pleural cavity

Front 13

Pericardial cavity

Back 13

contained within the mediastinum, a small chamber that surrounds the heart

Front 14

Pericardium

Back 14

serous membrane that lines the pericardial cavity

Front 15

Peritoneal Cavity

Back 15

contained within the abdominopelvic cavity, includes the abdominal cavity and pelvic cavity

Front 16

Abdominal cavity

Back 16

included in the peritoneal cavity and contains the liver, stomach, spleen, small intestine, and most of the large intestine
