I think that most of Emily Dickinson’s poems reflected an aspect of her personality or beliefs. However, I think that one that was probably most representative of who she was, was “The Soul Selects her own Society”. In the poem she says “The Soul selects her own Society /Then — shuts the Door —/To her divine Majority —/Present no more-” (Dickinson). The poem speaks of a person who has separated themselves from society. However, they do not cut themselves of fully whether they become extremely selective in who they will allow into their personal bubble. They subconsciously choose who ...

Pathophysiology of Chronic venous insufficiency and Deep venous thrombosis

Chronic venous insufficiency is a condition that describes a dysfunction of the valves in the upper and lower extremities or the inability of the muscles in these regions to exert the required pressure that can force the flow of blood back into the heart. Essentially, the arteries are designed to supply oxygen-rich blood to all parts of the body while the veins are designed to transport the oxygen-deficient blood back into the heart (McPhee& Hammer, 2010). These processes are enhanced by the pressure exerted by the underlying muscles within the upper and lower extremities as well as the ability ...
