1. have outer cortex n inner medulla
2. in cortex the lymphocytes arranged in segment w sinuses to allow lymph to pass
3. in medulla, lymphocytes arranged in strands forming medullary cored(produce antibodies)
4. as lymph pass the node, lymphocytes n antibodies clean lymph n remove anything that harm body
5. if there is infection, node become very active that cause them to swell n become painful
group of lymph nodes
1. during massage, we direct to node to aids return of fluid from tissue to blood
2. submandibular node
3. cervical node(side of neck)
4. axillary node(armpits n upper to lower chest)
