Study Notes
-
The immune system has two types of organs: primary and secondary
-
Primary lymphoid organs are sites of immune cell birth and development
-
Bone marrow is a primary lymphoid organ, where hematopoiesis occurs
-
Red marrow is the spongy portion of bone, where blood cells are produced
-
Yellow marrow is the fat storage part of bone marrow, present in adults
-
Hematopoietic stem cells differentiate into lymphoid and myeloid precursors in bone marrow
-
Common Lymphoid Progenitor (CLP) gives rise to lymphocytes, while Common Myeloid Progenitor (CMP) produces granulocytes, monocytes, red blood cells, and platelets
-
Central macrophages in the bone marrow facilitate iron transfer to erythroid progenitors
-
Aged erythrocytes and pathogens are filtered by macrophages in the bone marrow
-
Destinations for cells leaving the bone marrow include blood tissue, bone marrow, spleen, thymus, and lymph nodes
-
Secondary lymphoid organs are sites of immune cell storage, activation, and response to infection
-
Spleen is a secondary lymphoid organ, where newly formed B cells can enter and acquire a receptor
-
Red pulp in the spleen contains dendritic cells and macrophages that filter blood for antigens
-
White pulp, where B and T cells are localized, contains periarteriolar lymphoid sheaths and lymphoid follicles
-
Lymph nodes filter lymph and are compartmentalized, with different areas for naive B cells, follicular DC, activated B cells, T cells, and macrophages
-
Lymphatic system collects and transports lymph, which is a clear collection of fluid from the tissue, into lymph nodes and the venous circulation
-
Lymph nodes filter lymph and generate an immune response against pathogens
-
Valves in the lymphatics aid lymph flow, and mechanisms such as breathing, muscle contractions, and posture changes promote lymph movement
-
Lymphatic pump and smooth muscle contractions help in improving lymph flow
-
Damage to lymphatic tissue or nodes can result in swelling (edema) due to the accumulation of excess lymph.
