2 lateral pleural cavities
Mefiastinum |
|
Pleural cavities
|
Each contain one lung
|
|
Mediastinum

|
Diaphragm
|
Separates thoracic & abdominopelvic cavities
Important in breathing |
|
2 subsections of abdominopelvic cavity & their contents
|
Abdominal cavity - contains liver, spleen, stomach
Pelvic cavity- pelvis, urinary bladder, some reproductive organs & rectum |
|
Parietal serosa
|
Lines walls of ventral cavity
|
|
Visceral serosa
|
Covers the organs of the ventral body cavity
|
|
Abdominopelvic quadrants
|
Mostly used by medical personnel
RUQ - right upper quadrant LUQ - left upper quadrant RLQ- right lower quadrant LLQ- left lower quadrant Through umbilicus |
|
Serosa
|
Aka serous membrane
Double layered membrane in ventral cavitythat lines walls & outer surface of organs it contains |
|
9 abdominopelvic regions
|
Primsrily used by anstomists
2 transverse & 2 parasigittal planes Umbilical - centermost region, deep to & surrounding umbilicus Epigastric - superior to umbilical Hypogastric- inferior to umbilical Right & left iliac or inguinal - lateral to hypogastric Right & left hypochondria - lateral to epigastric & deep to ribs |
|
Synovial cavities
|
Joint cavities
Enclosed in fibrous capsules Secrete lubricating fluid |
|
Organs in right hypochondriac region
|
Liver
Gall bladder |
|
Serous fluid
|
Lubricating fluid that separates serous membranes
Secreted by both membranes Allows organs to slide without friction across walls & each other |

|
Catabolic vs anabolic
|
Catabolic - breaks down substances into simpler blocks
Anabolic- synthesizes (builds up) more complex cellular substances from simpler substances |
