Lymph node: paracortex
The paracortex or deep cortex is a T-dependent area possessing high endothelial venules (lined with simple cuboidal epithelium) and ordinary venules (lined by simple squamous epithelium). Lymphocytes leave the high endothelial venules to enter lymphatic tissue, where they initiate an immune response in the lymph node. 400x
