Body Cavities and Membranes Flashcards
serous membranes
thin sheets of tissues that form fluid filled body cavities
cells of serous membranes
produce a thin watery liquid called serous fluid
serous fluid
lubricates organs so they move within the cavity with little friction
what two layers make up serous membranes
parietal and visceral
parietal layer
attached to the body wall and surrounding structures
visceral layer
attached to specific organs
thoracic cavity
superior to the diaphragm; encompasses area incased by the ribs
plueral cavities
each cavity surrounds a lung
plueral membrane
2 layers of serous membrane
parietal pleurae
attached to body wall and surface of diaphragm
visceral pleurae
attached to surface of the lungs
mediastinum
cavity between plueral cavities
what is in the mediastinum
vessels, esophagus, trachea, bronchi, etc.
pericardial membrane
cavity formed by a second double layer serous membrane
parietal pericardium
cavity formed by a second double layered serous membrane
visceral pericardium
attached to heart muscle
pericardial cavity
filled with thin layer of serous fluid
abdominal pelvic cavity
inferior to the diaphragm and extends to pelvis
what is in the abdominal cavity
liver, gallbladder, part of the colon, small intestine, stomach, pancreas, kidneys, adrenal glands, spleen
what is in the pelvic cavity
certain sex organs, urinary bladder, rectum and part of the colon
what forms the peritoneal cavity
the parietal membrane which is a serous membrane
parietal peritoneum
attached to body wall and surrounding structures
visceral peritoneum
attached to surface of many abdominal and pelvic organs
intraperitoneal organs
organs that are within the peritoneal cavity
retroperitoneal organs
organs that are posterior to the peritoneal cavity
