Title: Lymphedema-HP
Description: Lymphedema; the top part of the drawing shows normal lymphatic flow. An arrow is used to show intravascular fluid flowing through an artery, an arteriole, and a capillary bed, where the fluid leaks out into the interstitial space around the cells and then exits through the venules. Also shown is interstitial fluid, large proteins, and cells entering a lymphatic vessel to maintain normal interstitial pressure. The fluid in the lymphatic vessel is called lymph. Also shown is the inside structure of a lymph node attached to the lymphatic vessel with arrows showing how the lymph moves into and out of the lymph node. The lymphatic ducts in the neck area of a female figure are also shown. The figure’s left arm is red and swollen. There is a pull-out from the swollen arm showing a top layer of red, hardened skin and an inset box showing obstructed lymphatic flow. A damaged lymphatic vessel resulting in increased interstitial pressure and a build-up of large proteins, cellular debris, macrophages, and lymphocytes are shown. Large fat cells and fibrosis are also shown in the inset box.
