<span>There are three primary systems in the body that act as a buffer, in order to help maintain pH stability.
The first is known as the phosphate buffer, which neutralizes excess hydroxide ions as they enter cellular fluid.
The second is called the protein buffer, and maintains acidity in the body. The hemoglobin in blood, which binds to acids in the bloodstream, is one such example of this system.
The third system is called the carbonic acid bicarbonate buffer, which neutralizes the acids generated by various metabolic processes, such as digestion and respiration.</span>

Cholinergic neurons release acetylcholine as a neurotransmitter. The cell bodies of preganglionic neurons of sympathetic division are present in the lateral horns of 12 thoracic and first two lumbar segments of the spinal cord. These are the cholinergic neurons and their axons release the acetylcholine as neurotransmitter into the synaptic cleft. The acetylcholine released by preganglionic sympathetic neurons binds to the cholinergic receptors present in the membranes of postganglionic neurons of the sympathetic division.
