An important advance in the study of the physiology of stress came with the discovery in the 1990s that stress triggers the release of which play a role in inflammation and fever.

Cytokines

Explanation:

Stress causes the release of cytokines. Cytokines are proteins. To fight infections cytonkines initiate a response to the immune system this causes inflammation.

Stress can also lead to an increase in a person's allergies. Basically when we are affected by stress our body thinks it is being attacked hence inflammation and the affects of fighting infection appear.

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.
