nodules are not surround by connective tissue
what is contained within lymphatic nodules
macrophages, dendritic cells and lymphovytes
what is the function of a lymphatic nodule
screen for and attack foreign antigens

macrophages and dendritic cells
what are the characteristics of lymphocytes
Most abundant cell type
B-lymphocytes, T-lymphocytes, and Natural Killer cells
Migrate through the lymphatic system searching for foreign antigens
what are the characteristics of macrophages and dendrite cells

Antigen presentation to lymphocytes to initiate immune response
what are the different types of lymphocytes
natural killer celss
what are the two main types of t-lymphocytes
helper t-cells CD4
cytotoxic t-cells CD8
how do helper t-cells work
Orchestrate an effective immune response by secreting cytokines (chemical signals that bind to and activate other immune system cells)
how do cytotoxic t-cells work
Kill abnormal cells by secreting substances that break down the cell’s membrane
what are the "other" types of t- cells
memory t-cells
regulatory t-cells
what is the function of memory t-cells
patro body after an attack

turn off immune response
once activated b-lymphocytes dived and becoem
plasma cells
memory b lymphocytes
plasma cells produce
immunoglobulins (anibodies)
-antibodies bind to antigens, tagging them for destruction
what is the function of memory b lymphocytes
patrol the body after an attack
easily activated if infected again
T/f NK cells can only respond to one type of antigen

NK cells can kill a wide variety of infected cells and some cancerous cells
