Organization Of The Body - Body Cavities

Front 1

anterior/ventral body cavity subdivides into

Back 1

thoracic cavity

*** diaphragm ***

abdominopelvic cavity

Front 2

posterior/dorsal body cavity subdivides into

Back 2

cranial cavity - brain

vertebral canal - spinal cord

Front 3

The body has __ main internal cavities which are then subdivided into smaller cavities. They are

Back 3

2

posterior/dorsal - head & neck

Anterior/ventral - torso (...Abdomen)

Front 4

viscera

Back 4

internal organs

Front 5

abdominopelvic cavity subdivides into

Back 5

abdominal cavity

pelvic cavity

Front 6

the mediastinum is contained in which cavity?

Back 6

the thoracic

contains the heart, thymus, trachea, esophagus &c.

Front 7

pleura

Back 7

serous membrane surrounding lungs, space between - pleural cavity - is filled with pleural fluid

parietal & visceral

Front 8

parietal pleura

Back 8

serous membrane around lungs, next to thoracic wall

Front 9

visceral pleura

Back 9

serous membrane, adheres directly to lungs

Front 10

visceral pericardium

Back 10

serous membrane, adheres directly to the heart

Front 11

parietal pericardium

Back 11

serous membrane around the heart separated by the pericardial cavity

Front 12

peritonitis

Back 12

inflammation of the peritoneum

Front 13

many of the organs of the abdominopelvic cavity are covered by

Back 13

the visceral peritoneum

Front 14

the wall of the abdominal cavity is lined with

Back 14

the parietal peritoneum

Front 15

homeostasis

Back 15

the relative constancy of the body's internal environment

Front 16

negative feedback

Back 16

the primary homeostatic mechanism that maintains balance in the body

(vs positive feedback, which pushes change in the same direction)

Front 17

positive feedback

Back 17

a mechanism that brings about an ever greater change in the same direction

(e.g., a fever causing metabolic changes which push the fever still higher)
