The respiratory system is a vital factor of gas exchange due to its structures. The structure provides an efficiency to the process. Gas exchange requires an efficient system because it is a process through which blood circulates around the body‚ collects oxygen‚ delivers the oxygen to the organs that require it and releases carbon dioxide. oxygen and carbon dioxide enter and exit the body in opposite directions across a respiratory surface area that supplies enough oxygen to allow the process to

Three different general types of spinal cord models consist of contusion‚ compression and transection \cite{rosenzweig2004}. Each model contains the different advantages and disadvantages depending on the observing study. When a blunt force exposes to the spinal cord without the destruction of the dura‚ it develops the contusion model which is the most general case in human \cite{jackson2004‚calancie2005}. The impactor is the confined tool to induce the contusion model with repeatability

Arteriosclerosis occurs when blood vessels called arteries‚ which transports blood from the heart to the rest of the body‚ becomes thick and hard preventing normal blood flow to organs and tissues. Normal healthy arteries which transports oxygen and nutrients in blood are flexible and elastic‚ however overtime can harden. (Mayo Foundation for Medical Education and Research‚ 2015) 1. Arteriosclerosis also termed hardening of the wall of the arteries can be generated by deposits of lipids on the inner

commonly‚ fistulas can also be created in the lower extremities‚ creation process however differs. AV fistula placement is done in groin only when options in the arm and hands are either not available or are exhausted due to failure of fistulas previously created in the arms. A fistula takes many weeks to mature‚ on average perhaps 4–6 weeks. During dialysis treatment‚ two needles are inserted into venous column of the fistula‚ one draws blood to the dialysis machine and the other one to return it

In addition‚ the minimally-invasive surgical techniques which are now used to treat aneurysms can mean a recovery time of around four weeks‚ compared to over a year for older procedures. Hence‚ all in all‚ medical technology plays a vital role in allowing people to remain valuable and contributing members of the society. Thus i shall end
