Instead the plates slide horizontally past one another. No matter the type of boundary though, the movement of the Earth's tectonic plates is essential in the formation of the various landscape features we see across the globe today.
As the death rattle does not always respond to these interventions, Bennett conducted further research into this phenomenon and came up with the conclusion that there is more than one type of death rattle. Physiological Theory: Causes of Death Rattle. Bennett (1996) identified two different types of death rattle. Type I is caused by an accumulation of salivary secretions when swallowing reflexes are inhibited and type II is caused by an accumulation of bronchial secretions in patients too weak to cough effectively (Bennett, 1996).
A sound characteristic of end-stage lung diseaseâe.g., terminal lung cancer or pulmonary oedemaâthat occurs when the clearance of large airway secretions becomes nearly impossible; as air moves to and fro in the bronchi, the sound acquires a gurgling or rattling quality, often presaging death death rattle
