What is the physical occurrence that makes lymph nodes swell?
1. Your nervous system notices an infection and facilitates the relaxation of smooth muscle around lymph nodes, which allows them to get bigger
2. There are increased numbers of memory B cells, plasma cells, and cytotoxic T cells in the lymph node
3. Epithelial cells that line the lymph node replicate and add more layers of cells to the lymph node
4. There are large amounts of histamines present in the lymph nodes, which causes blood vessels inside the nodes to vasodilate
How are innate lymphoid cells, including natural killer cells, distinguished from lymphocytes?
a- stimulation by pathogen associated molecular patterns
b- single lobed nucleus
c- production of cytokines
d-expression of rearranged antigen receptors
