DISORDERS OF THE VEINS AND ARTERIES 2 Disorders of the Veins and Arteries Chronic venous insufficiency (CVI) and deep vein thrombosis (DVT) are chronic disorders with separate pathologies and distinct clinical presentations. Both occur due to impaired circulation in the veins and arteries. Arterial disorders are precipitated by altered platelets, in contrast venous disorders are related to a dysfunction in the clotting system. CVI is said to be a malfunction of the valves in the veins of the lower extremities ( Liu, R., Guo, X., Lao, T. T., & Little, T. (n.d). The malfunction allows the blood to “reflux” and increases the pressure inside the veins(Eberhardt, R. T., & Raffetto, J. D. (2014). This malfunction causes difficulty in the return of blood to the heard. The deep veins (collateral veins) causing pooling of the blood in the lower extremities. The stagnant blood in the lower extremities begins an inflammatory reaction in the tissues. The obstructed outflow of blood causes increase muscle contraction and cause the muscle pump to become dysfunctional.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
