Did you get the same blood pressure reading manually as you did with the use of probes? provide at least two reasons these value

s may be different. what are two causes of blood pressure changes that might occur in a person within a given day? what did you need to keep constant in your experiments? why was it important to keep these factors constant? what is prehypertension? why do you think it is valuable to know if you are considered prehypertensive? explain how an ace inhibitor might have helped anna mediate her blood pressure.

Part I
NO, this is because of different judgement as to when pulse start/stops.
In addition, computers are more sensitive than probes, prob could be more accurate because it does not have human error, which manual method has. Other factors that affect the reading may include temperature, eating, body position among others. 

Part II
The causes of changes in blood pressure that might occur within a given day include; stress and level of activity. Eating a flux of nutrients like sodium could affect the blood pressure. Also different requirements from the body . Therefore, if one is lying down versus when one is standing up, it might take more energy standing up, such that when one is relaxing lying down, blood pressure will be lower due to the relaxation.

Part III
What is needed to be kept constant through out the experiment is; 
same person, same amount of time in between readings or for the readings, same pressure that is pumped at the beginning, same temperature.
It is important to keep all those factors constant because if not, the factors that are not iv's could change the data. keep the same person because data can change a lot based on who you use while retrieving the data.

Part IV
Prehypertension is the sign that one might have high blood pressure in the future. it is valuable to know if one is considered prehypertensive because one can implement proper changes to lifestyle in order to maintain a healthy blood pressure.  

Part V
An ACE inhibitor works by blocking the body from producing angiotensin II which causes blood vessels to become narrower, raising blood pressure. This stops the chemical, thus relaxing the blood vessels and also lowering the blood pressure.
