Lymphatic System

Helper T-cells are white blood cells. Most white blood cells kill or "hijack" infected host cells as they fight disease and infection. Unlike other white blood cells Helper T-cells do not have a capability to kill or take over the infected host cells, so their contribution in fighting disease and infection is by activating and directing the proper white blood cells to the infected host cell which needs killing or "hijacking".

I think comparing it to a GPS system in your automobile would make it simpler. While you may know WHERE you are supposed to go, the GPS shows activates and gives you directions. most any of the GPS's will "Activate" or "alert" you by speaking aloud and then giving directions "Turn Right ahead" or "Proceed ahead for 1 mile and turn left onto..." thus activating you how and where to drive the car to get to the proper destination.

Well I learned in Biomedical that the Immune system fights off infection on your pecker.

Yes

the immune system does aid in protecting your body fight against disease or foreign bodies, but the main soldiers are your white blood cells which surround whatever germ or disease in the body and kills it. The more healthy you are the better your body can defend against these foreign bodies, viruses whatever you call them.

Lymphatic System(A+)

The human spleen is an organ. It creates lymphocytes for the destruction and recycling of old red-blood cells. It is also a blood reservoir. It also can supply the body with blood in emergencies like a bad cut. Also, it is the location where white blood cells trap organisms. The spleen is part of the lymphatic system, not digestive.

There are many drugs that weaken the immune system, but people would likely be most familiar with corticosteroids (eg: Glucocorticoids). Corticosteroids are produced naturally by our bodies, but are also commonly given in higher doses to treat many different human ailments, such as asthma (an asthma puffer is often administering corticosteroids). The immunosuppressant nature of corticosteroids is exactly why they are effective drugs. For example, the symptoms of arthritis, an inflamatory disease (inflammation is caused by the immune system), are alleviated by corticosteroids by reducing the inflammation. Someone who is about to undergo an organ transplant will also often have their immune system suppressed with corticosteroids so that the transplanted organ will be less likely to be rejected.

Thoracic duct

In lupus, as in all other autoimmune diseases, the immune system does not attack itself. Rather, the immune system is confused and attacks health parts of the self such as organs and joints. The exact cause of these diseases is not known. Researchers have identified some genes that are responsible. But even if a person has a genetic predisposition to autoimmunity, it may never develop. Triggers are also involved. Cigarette smoke, the Epstein Barr virus, and sunlight are known triggers in lupus, although others are suspected.

No

The pituitary system is like a size of a pea.

Directly from my anatomy and physiology book - Marieb & Hoehn Eighth Edition:

"Lymphocytes originate in red bone marrow from hematopoietic stem cells."

" B cells become immunocompetent and self-tolerant in the bone marrow."

well...phagocytes are mainly part of the immune systems defense system, like when there is an inflammatory response. While lymphocytes are mainly for when the immune system attacks a foreign organism. However, lymphocytes can become phagocytes that's why i didnt say that they were part of a certain sector of the immune system.

The pineal gland is an endocrine gland located in the center of the brain (of vertebrate animals). It resembles a pine cone, which is the origin of its name. This gland produces serotonin and derivative melatonin. Melatonin is a hormone that regulates sleep patterns.

The movement of lymph through lymphatic vessels is caused mostly by movement, however lymph pressure also plays a part.

T cells are a specific type of lymphocyte that are identified via immunologic staining; they are involved in the cell lysis portion of the immune response to viruses and intracellular bacteria.

Howdy there!

HIV (human immunodeficiency virus) infects the T helper cells, the ones that are super crucial for activating T killer cells and B cells for a full-blown adaptive immune system response against a disease that can be dealt with easily. Without the T helper cells, the HIV infected person will suffer from the measliest of diseases, and also get cancer, especially Kaposi's sarcoma (a type of nasty herpesvirus).

Thank you for the question! 😄

histamine

this is bullcrap!

what kind of infection can cause a swollen lymph node in the left breast

Antibody

- produced by B lymphocytes.

Anti gens bind to viruses/bacteria that 'fit' them, clumping together and allowing phagocytosis. They tend to be specific to one strain hence why we cannot vaccinate against a virus that mutates frequently or has many strains.

The job of the lymphatic system is to detect, filter and remove bacteria and other foreign invaders while maintaining fluid balance.

The thoracic duct drains the abdomen from both the left and right lumbar trunks. This lymph is also said to be the largest lymphatic vein.
