Lymph(Endocrine/Immune) System This one is super important…
Lymph (Endocrine/Immune) System The immune system is made up of many different cells, organs, tissues and substances within your body. Each aid in eliminating foreign organisms from your body and protecting you from various diseases and illnesses. These foreign organisms come in the form of viruses, bacteria, parasites and fungi. They are known as “microbes.”
First Line of Defense – The Skin The skin is thick and very hard to penetrate and produces a variety of substances that are harmful to invaders. The eyes, nose, and mouth are protected by fluids or sticky mucus that capture harmful attackers. The respiratory tract has cilia, tiny hairs that remove particles. Intruders that get as far as the stomach are up against a sea of stomach acid that kills most of them.
Second Line of Defense – White Blood Cells There are several types of immune cells, each possessing specific duties and characteristics. Several travel through the body killing foreign substances as they find them. Others patrol the gastrointestinal tract lining and blood vessels, safeguarding particular organs.
The lymphatic system, which includes the lymph nodes, the spleen, bone marrow and thymus gland, produces these cells and transports them throughout the body. Lymph nodes and the spleen serve as filters designed to keep harmful organisms out of the blood stream. Most immune cells are produced in the bone marrow, the thymus or the spleen.
Lymph (Endocrine/Immune) System Lymph Nodes - Controls against invaders such as bacteria and viruses Maintains/produces white bloods cells (B cells, T cells) to battle against foreign cells in the body. Prevents major illnesses from taking over the body
Diseases/afflictions of the lymphatic system Lymphoma (cancer) Leukemia (abnormal WBC) Any other infections acne
