The most biologically devastating oil spills in the marine environment are usually a result of the sinking of oil tankers.
An oil spill is a type of pollution that occurs when a liquid petroleum hydrocarbon is released into the environment, particularly the marine ecology.
Oil releases into the sea or coastal waterways are generally referred to as marine oil spills, however land-based spills are also possible.
Oil spills can result from crude oil discharges from tankers, sinking of oil tankers, offshore platforms, drilling rigs, and wells as well as refined petroleum products (like gasoline and diesel) and their byproducts, heavier fuels used by big ships like bunker fuel, or the spill of any oily waste or garbage.

The neurotransmitter that is released by the axon of a sympathetic preganglionic neuron to communicate with the sympathetic postganglionic neuron is Acetylcholine. Acetycholine is the neurotransmitters released by the postganglionic neuron in sympathetic division. Acetycholine is responsible for the stimulation of muscles, including the muscle of the gastro-intestinal system. It is also found in sensory neurons and in the autonomic nervous system and has a part in scheduling REM sleep.

The inner lining of your gut and lungs also produces mucus to trap invading pathogens.
