The first commercial product to use a microprocessor was the Busicom calculator 141-PF. The 4004 was also used in the first microprocessor-controlled pinball game, a prototype produced by Dave Nutting Associates for Bally in 1974.
3 doctors weighed in: Can post nasal drip result in mucus entering into lungs and accumulating there, or does it just go in stomach ? 3 doctors weighed in Want a second opinion? A little post nasal drip may try to enter the lungs & trigger a strong protective cough. If it went in with any volume you would have a significant pneumonia almost immediately. Most enters the esophagus/stomach & digestive pathway to be broken down over time.
(Mucus can also form in the lungs, which is the case in patients with asthma and chronic bronchitis. When that happens nerves in the bronchi are stimulated, resulting in cough.). Mucus dripping from the nose or sinuses is called post nasal drip (PND). PND is the most common cause of chronic cough. If mucus stayed in the nasal passages and sinuses -- if it did not drip into the back of the throat and down toward the lungs -- then rhinitis and sinusitis would be an uncommon cause of cough.
