The lymphatic system helps maintain fluid balance in the body by collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream. It also helps defend the body against infection by supplying disease-fighting cells called lymphocytes.
The lymphatic system plays an integral role in the immune functions of the body. It is the first line of defense against disease. This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad).
Secondary lymphoid organs are site in which mature lymphocytes congregate to mount immune responses. Many immune system cells use the lymphatic and circulatory systems for transport throughout the body to search for and then protect against pathogens.
The lymph nodes play host to a series of complex cellular interactions that typically lead to activation of residing cells, the lymphocytes and macrophages; depending on what they detect at the lymph node, they can activate locally in the node or activate immunity systemically outside the node.
The lymphatic system is one of two major systems responsible for moving fluid around your body. The other is the cardiovascular system. These two circulatory systems work together to make sure your body’s tissues can get what they need and get rid of what they don’t need.
The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with.
Lymph nodes play a key role in filtering out bacteria and other harmful substances while also exposing them to infection-fighting white blood cells and triggering an immune response. The more lymph nodes you have removed, the greater the disruption to your immune system.
The immune system works to keep these harmful agents out of the body and attacks those that manage to enter. The lymphatic system is a system of capillaries, vessels, nodes and other organs that transport a fluid called lymph from the tissues as it returns to the bloodstream.

Humans have three types of immunity — innate, adaptive, and passive: Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. For example, the skin acts as a barrier to block germs from entering the body.
The main parts of the immune system are: White blood cells: Serving as an army against harmful bacteria and viruses, white blood cells search for, attack and destroy germs to keep you healthy. White blood cells are a key part of your immune system. There are many white blood cell types in your immune system.
- The innate immune system. You are born with this.
- The adaptive immune system. You develop this when your body is exposed to microbes or chemicals released by microbes.
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel).
An important difference between T-cells and B-cells is that B-cells can connect to antigens right on the surface of the invading virus or bacteria. This is different from T-cells, which can only connect to virus antigens on the outside of infected cells. Your body has up to 10 billion different B-cells.
