WHY & WHY!!!

WHY Blood Flow? - not arteries-

•  Blood circulation is essential for body. Every cell in the body needs to received oxygen and nutrients. Blood rich in oxygen is sent to the body organs, tissues and cells to nourish them, and the waste products that result are disposed of through the same system.  Simply the body cannot function well without a strong circulatory system.
• Lack of studies which has been dedicated directly to examine the effect of smoking to the blood flow.

WHY Upper Limb Arteries?

If we look into the arterial system (refer to picture below) we can see that the best place to examine the blood flow is the arteries of upper limb for these reasons:

• Near to heart so we can see the blood speed and the blood pressure defferences easily.
• Near to surface (skin) so we can scan it easily and accurately.
• Branched into to terminal arteries so it is provide us enhancement of reading.

WHY Doppler Ultrasound?

Any regular ultrasounds uses sound waves to produce images, but non of them can show blood flow. Doppler the only one which can measure our blood flow and blood pressure.

WHY MATLAB Simulation?

Becuase MATLAB very familiar and popular engineering field. In 2004, MATLAB had around one million users across industry and academia. MATLAB users come from various backgrounds of engineering, science, and economics. MATLAB is widely used in academic and research institutions as well as industrial enterprises.
