Which type of serous membrane is located within the lower mediastinum? parietal peritoneum parietal pericardium parietal pleura visceral pleura

parietal pericardium The pericardial cavity, lined with parietal pericardium, occupies the lower part of the mediastinum.

The membrane that lines the thoracic cavity walls is the __________. parietal peritoneum parietal pericardium visceral pleura parietal pleura

parietal pleura The thoracic cavity contains the lateral pleural cavities and the medial mediastinum. Parietal serosas are found on cavity walls.

Which of the following correctly describes the function of serous fluid?

reduce friction between the organs of the ventral cavity Organs and the cavity walls in which they sit are covered with serous membranes. These membranes secrete serous fluid to allow organs to move and slide within the ventral cavity as they carry out their normal functions.

If a patient experiences inflammation of the membrane on the surface of the stomach, which membrane is affected? visceral peritoneum parietal pericardium visceral pleura parietal peritoneum

visceral peritoneum Visceral serosas are found on organ surfaces, and membranes within the abdominopelvic subdivision of the ventral cavity are described as peritoneum.
