How do I write an introduction for a research paper on blood pressure?

An effective introduction for a research paper presents a concise summary of what the reader should expect to learn from the paper. In a scientific research paper, the introduction is presented as a leading and separate section of the paper, and presents a summary of the purpose, methods, clinical results and conclusions of the study. It should be constructed only after other sections of the paper are complete. If the paper is a topical review of blood pressure, the scope and intended audience of the paper should first be identified. The content contained in the introduction and the paper will be dependent on these parameters. For a review paper on human blood pressure, the introduction should define blood pressure physiologically, discuss how blood pressure is regulated and measured, delineate normal vs. abnormal measurements, and identify factors associated with abnormal readings. This should be followed by a discussion of measures for treatment, and a conclusion citing current trends in research regarding blood pressure.
