I am interested in the mechanism between the dry cough and runny nose (serous inflammation) here. I started to think how Acute respiratory viral infection is causing the dry cough.
The serous membrane, pleura pulmonalis, connects diaphragma to pars basalis pulmonalis. It can be the source of the serous inflammatory response spreading to the nose probably. There must be some source of inflammatory responses such that reflex arches can use them fast, thinking physically.
Assume medication Montelukast (stop asthmatic symptoms), codeine (to stop irritated dry cough) Flixotide (with Montelukast). Assume that there is a diaphragm press on pars basalis pulmonalis. Assume you breath mostly by abdomen 15 minutes in the supine position. Assume opposite-astonic person in thorax. You then feel that you exhale too much - the serous membrane pushing on pars basalis pulmonalis - serous inflammatory response in pleura pulmanalis. The breathing process moves thoracic muscles and thoracic cavity gets shortly extended only little. Negative tensor on lungs i.e. the volume of the lungs is getting smaller. Consequently, a cough reflex arch and sympaticus start a deep dry cough to protect lungs.
Characteristics of the pathway against Acute respiratory viral infection
- serous inflammation on pleura pulmonalis
- serous membrane pleura pulmonalis presses on pars basalis pulmonalis
- negative tensor on lungs
- cough reflex arch and sympaticus
- dry cough
- positive gradient on the pleura spreads inflammatory response through the surrounding lymphatic system is sensed as dry in larynx
- negative gradient is sensed on the nasal mucosa membranes as serous inflammation (runny nose)
Can the serous inflammation of plera pulmonalis cause a deep dry cough and runny nose? The cause of this inflammatory response can then be Acute viral respiratory infection in some part of the lungs.
