research paper

need to research information regarding blood pressure including:

What is measured (obviously blood pressure but for the paper you need to be specific)?

What are some of the major factors that affect blood pressure?   Do these factors "normally" affect blood pressure consistently or do they only occur when there is a problem?

Does it appear that abnormal blood pressure can alter or affect the way blood cells normally look or function?  

Papers will need to be typed with standard 1” margins.  Double spaced.  

Approximately 3-4 pages long but content is more important than length.

You must make sure to cite all references (APA format).
