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 outer layer is called the parietal pleura and lines the thoracic wall, and the inner â¦ layer is called the visceral pleura and covers the lungs. The membranes produce lubricating serous fluid that causes them to adhere closely to one another.he outer pleura is attached to the chest wall and is known as the Parietal pleura; the inner one is attached to the lu â¦ ng and other visceral tissues and is known as the Visceral pleura. In between the two is a thin space known as the pleural cavity or pleural space.
