Question

Put the following structures in the correct order, going from the outermost to the innermost structure:

a. parietal pleura
b. chest wall
c. visceral pleura
d. interpleural space
e. lungs

a) b, d, a, d, e
b) b, a, d, c, e
c) e, c, d, a, b
d) b, c, a, d, e

Answer 1

The correct order of structures from outermost to innermost is chest wall, parietal pleura, interpleural space, visceral pleura, and lungs; making the sequence b, a, d, c, e. The correct option is b).

Step-by-step explanation:

When arranging the structures from the outermost to the innermost, the correct order is: chest wall, parietal pleura, interpleural space, visceral pleura, and lungs. Therefore, the correct sequence in letter options provided to the student is b, a, d, c, e.

To clarify, the chest wall is the outermost structure, followed by the parietal pleura which lines the thoracic cavity. Next comes the interpleural space which contains a small amount of fluid that helps reduce friction. The visceral pleura is the layer directly superficial to the lungs, covering them and extending into the lung fissures. Lastly, the lungs are the innermost structures within this sequence.
