For the heart, the surrounding serous membranes include:

Therefore each organ becomes surrounded by serous membrane - they do not lie within the serous cavity.

All serous membranes found in the human body formed ultimately from the mesoderm of the trilaminar embryo.

The somatopleure is associated with the overlying ectoderm and later becomes the serous membrane in contact with the body wall.

The intraembronic coelom can now be seen as a cavity within the body which is covered with serous membrane derived from the splanchnopleure.

Quick post-mortem examination will lead to the discovery of many haemorrhagic patches on the serous membranes, and intense pneumonia.

The pleura is a serous membrane which folds back onto itself to form a two-layered membrane structure.

Each of the organs is covered in a double layer of fascia; these layers are separated by a thin serous membrane.

If the serous membrane is involved, colonic perforation may ensue.

It is relatively inelastic and protects the heart and the serous membranes.
