For this question, we're looking at certain feed -forward mechanisms.
00:07
So you can imagine this is going to be the opposite of, say, a feedback mechanism, which you might be more familiar with.
00:16
So feedback mechanisms cause a change in the body based on some sort of level being measured in the body.
00:26
So it's going to measure the level or the state of the body and cause its change.
00:32
As opposed to the feed forward mechanism where you're going to have that change first in preparation for a required level.
00:42
So really these are preparations mechanisms of the body.
00:49
So you can imagine that these would be sort of stimulatory signals such as hearing somebody yell when you want to run away later or saying to get ready during the beginning of of a race.
01:06
So if we're looking at the regulation for blood pressure and breathing, these are both very significant to the fight or flight response.
01:23
So this would be, say, encountering a bear in the woods, your blood pressure would suddenly jump and your breathing may suddenly jump as well in preparation to either run away from the bear or to fight it, which i do not recommend.

Alternatively, you have the secretion of digestive enzymes...
