protect the heart and lungs
make the movements of breathing
breast tissue - lactation

8

9

The chest cavity consists of the mediastinum and the R and L pleural cavities - true or false?

true

10

During development the lung bud penetrates the pleural cavity - true or false?

false
the lung bud pushes against but never enters the pleural cavity

11

Where does the lung bud originate from?

the mediastinum

12

Development of the lung bud into the pleural area causes the development of a ______ and _______ pleura

visceral, parietal

13

The parietal pleura is the part which attaches to the....

chest wall

14

The visceral pleura is the part which attaches to the...

lung

The pleural fluid does two things, these are?

act as a lubricant
create surface tension

16

What does the pleural surface tension ensure?

the lungs move with the pleural fluid and thus inflate
