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.

Pleura The pleural cavity is a closed space (like the inside of a balloon) within which the lung has grown. As the lung grows into the space, it picks up a layer of pleura (outside of balloon) and this is called the visceral pleura. The remainder of the pleura is called the parietal pleura.Pleura is a membrane that is single celled.s the lung grows into the space, it picks up a layer of pleura (outside of balloon) and this is called the visceral pleura.
