Question

Which of the following is directly attached to the wall of
the thoracic cavity?
Alveolar epithelium
.
Parietal pleuron

visceral pleuron

pleural cavity​

Answer 1

Answer:

The pleural cavity is a potential spacebetween the parietal and visceral pleura. It contains a small volume of serous fluid, which has two major functions. It lubricates the surfaces of the pleurae, allowing them to slide over each other. ... Note how the two layers ofpleura are continuous at the hilum of the lung.

Answer 2

Parietal pleuron is the correct answer.

• Thoracic cavity also known as chest cavity is the hollow region surrounded by vertebral column, sternum and ribs. It is separated by abdominal cavity by the presence of diaphragm.
• The inner surface of thoracic cavity, i.e. the area of inner side of ribs is attached to parietal pleura.
• Further there is visceral pleura present and the space between parietal and visceral pleura is known as pleural cavity, which is filled with pleural fluid.
