The valleculae can collect saliva to prevent initiation of the swallowing reflex. The vallecula is an important reference landmark used during intubation of the trachea. The procedure requires the blade-tip of a Macintosh-style laryngoscope to be placed as far as possible into the vallecula in order to facilitate directly visualizing the glottis .
Scientists have studied the impact of plastic on the ecological environment for decades and have raised concerns about the health effects of some chemicals used in plastics.
Medical plastics include a wide range of products from bags to pharmaceutical containers that leach and expose patients and healthcare workers to MNPs. [73] Further research is needed to assess toxicology and medical significance of MNPs from medical plastics. Microplastics per square meter in the EU sewage sludge (2015–2019) [74]
The Microbead-Free Waters Act of 2015 is a United States law that prohibits the addition of plastic microbeads in the manufacturing of certain personal care products, such as toothpaste. The purpose of the law is to reduce water pollution caused by these products.

Achalasia is a major exception to usual pattern of dysphagia in that swallowing of fluid tends to cause more difficulty than swallowing solids. In achalasia, there is idiopathic destruction of parasympathetic ganglia of the Auerbach's (Myenteric) plexus of the entire esophagus, which results in functional narrowing of the lower esophagus , and ...
As plastic breaks down over time, it degrades into smaller and smaller bits ‒ eventually small enough to slip inside the human body. Most of the plastics the scientists found in brain, kidney ...
Oxo-degradation refers to the breakdown mechanism caused by heat, light or oxygen on plastics that contain additives that accelerate the process of breaking them into smaller fragments called microplastics. [1] These plastics contrast biodegradable or compostable plastics, which decompose at the molecular or polymer level. [2]
