Carbon-laden lymph node

Image: The carbon-laden lymph node depicts the following structures:

• Carbon-laden lymph node: This is the center of the image, surrounded by adipose tissue (orange).

• Adipose tissue (around the lymph node): Surrounding the lymph node, colored orange.

• Fibrous capsule: Surrounding the lymph node, colored blue.

• Secondary lymph nodules: Small circular structures, colored orange, distributed throughout the lymph node.

• Subcapsular sinus (located below the fibrous capsule, outside the lymph nodules): Located just below the fibrous capsule, colored orange, containing lymphocytes.

• Perinodular sinus: Surrounding the lymph nodules, colored blue, containing lymphocytes.

• Carbon-laden macrophages: Cells colored orange, containing black carbon particles, distributed within the sinuses.

Details:

• Carbon-laden macrophages are primarily found within the subcapsular sinuses and perinodular sinuses.

• Lymph sinuses meander between the lymphoid tissue and secondary lymph nodules, colored orange, containing lymphocytes, macrophages, and lymph fluid.

• Secondary lymph nodules contain lymphocytes (orange) and plasma cells (orange).

Note:

• Orange arrows point to structures colored orange.

• Blue arrows point to structures colored blue.

• The rectangle indicates the area of the perinodular sinus.
