Posts: 213. I have been using various search engines to find information on Cat emissions and the uk law surrounding them. I have failed to find any proof that you *actually* require a cat to be fitted to your vehicle during an MOT test. the only thing I'm sure of is that it must pass the actual emissions test itself.hen the Carbon Monoxide passes through the catalytic Converter it is oxidised meaning that Another oxygen atom will be added to it, causing The Carbon monoxide to have one part Carbon and Two atoms of oxygen, therefore turning the Carbon Monoxide into Carbon Dioxie.
The parietal pleura is attached to the wall of the thoracic cavity and innervated by the intercostal nerves and phrenic nerve. Parietal pleura lines the thoracic wall, covers the superior surface of the diaphragm and separates the pleural cavity from the mediastinum.he parietal pleura is attached to the wall of the thoracic cavity and innervated by the intercostal nerves and phrenic nerve.

The pleurae, which contain the lungs, lie on either side of the mediastinum within the chest cavity. Each pleura is made up of two layers: parietal layer and visceral layer.The parietal layer lines the thoracic wall and covers the thoracic surface of diaphragm.It also lines the lateral aspect of mediastinum and extends into the root of the neck where it lines the undersurface of supra-pleural membrane.he pleurae, which contain the lungs, lie on either side of the mediastinum within the chest cavity.
