Hyoid Bone

24
Q

26
Q

A delicate, double walled sac or membrane containing the lungs is called

A

Pleura

27
Q

The outer layer of this membrane adhering to the inner surface of the chest wall and diaphragm is the

A

Parietal Pleura

28
Q

The inner layer adhering to surface of the lungs is

A

Visceral or Pulmonary pleura

29
Q

Potential space between these two layers (Parietal pleura and pulmonary pleura) is called the

A

30
Q

31
Q

Name 3 parts of the lung

Apex
Hilum
Base

A

Hilum

34
Q

Why is the left lung smaller than the right lung and why is the right hemidiaphragm positioned higher than the left hemidiaphragm
