Left lung (2 lobes)

What part of the lungs is this?

Cardiac notch

What cavity is this?

Pulmonary cavity

What cavity is this?

Pleural cavity

Mucous membranes

Location: Line the respiratory tract (e.g., nasal cavity, trachea, bronchi).

Function: Secrete mucus to trap dust, debris, and microbes; moistens and warms incoming air

on organs OPENED to environment

Serous membranes

Location: Surround the lungs and line the thoracic cavity.

Two Layers:

Parietal Pleura: Lines the inside of the thoracic cavity.

Visceral Pleura: Covers the surface of each lung.

Function: Produce pleural fluid to reduce friction during breathing and help the lungs adhere to the chest wall for expansion.
