This means different internal cell states e.g. signalling molecules, ion concentrations,...

comment Hypovolemia and orthostatic hypertension
Orthostatic (=postural) hypertension is an excessive increase of blood pressure upon standing up. Hypovolemia is a reduced total blood volume (i.e. lack of plasma). This question is perfectly on-topic.

comment What type of insect is this?
Edit your answer to include that and provide a reference or picture for the question author to check up themselves and I would say this is a perfectly sufficient answer :)
