The phrenic nerve innervates the diaphragm, enabling its contraction for breathing.

The cupula covers the apex of each lung, aiding in respiratory movements.

Costal surface of the lung is attached to the thoracic wall via ligaments.

Parietal pleura lines the inside of the thoracic cavity.

Pleural cavity is the space between the parietal and visceral pleurae.

Pleural fluid reduces friction, enabling smooth lung expansion.
