常见问题

What are the two layers of a serous membrane?
A serous membrane consists of two layers: the mesothelium — a single layer of flattened epithelial cells that secrete serous fluid — and an underlying connective tissue layer that provides structural support and anchors the membrane. Together, these layers form a smooth, moist surface that reduces friction between moving organs.
What are the main serous membranes in the human body?
The three principal serous membranes in the human body are: the pleura (lining the thoracic cavity and covering the lungs), the pericardium (enclosing the heart), and the peritoneum (lining the abdominal cavity and covering abdominal organs). Each forms a closed sac with parietal and visceral layers separated by a thin film of serous fluid.
What conditions affect serous membranes?
Serous membranes can become inflamed or develop excess fluid accumulation. Pleuritis (pleurisy) affects the pleura, pericarditis affects the pericardium, and peritonitis affects the peritoneum — each causing pain and potentially impairing organ function. Malignant mesothelioma is a cancer arising from mesothelial cells, often linked to asbestos exposure.
