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 of the Lungs. The pleura includes two thin layers of tissue that protect and cushion the lungs. The inner layer (visceral pleura) wraps around the lungs and is stuck so tightly to the lungs that it cannot be peeled off.The outer layer (parietal pleura) lines the inside of the chest wall.The very thin space between the layers is called the pleural cavity. A liquid, called pleural fluid, lubricates the pleural cavity so that the two layers of pleural tissue can slide against each other.By Healthwise Staff.he outer layer (parietal pleura) lines the inside of the chest wall.
