Today’s Agenda
Turn in your colored lymph node if you’ve not done so already.
Progress reports Notes on immune system Practice identifying parts Describe last illness Non-specific immunity

Other Lymphoid Organs:These organs don’t filter but do contain macrophages and lymphocytes.
1. Spleen: – a.Destroys old or defective red
blood cells– b.Stores platelets– c.Acts as a hematopoietic site in the
embryo and in severe cases of anemia

Other Lymphoid Organs:These organs don’t filter but do contain macrophages and lymphocytes.
2.Thymus gland– A. Most functional during youth– B. Its hormones cause T
lymphocytes to become immunocompetent.

3.Tonsils and Peyer’s patches– A.Small organs known collectively ast
GALT (gut-associated lymphatic tissues).
– B.Prevent pathogens in the respiratory and digestive tract from going through the mucous membrane lining

Obj. 5 Nonspecific Defenses: things your body uses to defend against ANYTHING
1. Skin & mucous membranes2. Phagocytic cells3. Natural killer cells4. Inflammatory response5. Antimicrobial substances6. Fever

Obj. 5 Surface Membrane Barriers
Role=prevent pathogens from entering bodyProtective membranes line all body cavities
and organs exposed to the exterior.Surface membranes provide mechanical
barriers to pathogens.Structural modifications and produce
secretions that enhance their defensive effects (skin acidity, lysozymes, mucus, keratin, cilia)

2. Phagocytic cells--macrophages
i. Phagocytes include macrophages and neutrophils
ii. Phagocytes engulf and destroy pathogensiii. Phagocytosis is enhanced when
pathogens surface is altered by antibodies or complement proteins
iv. Cell killing is enhanced by respiratory burst

3. Natural killer cells – attack and lyse body cells infected by viruses or that are cancerous.
![Page 18: Immune System Day 3 Health can be squandered, but not stored up. Mason Cooley (b. 1927),](https://reader030.vdocument.in/reader030/viewer/2022032517/56649c9c5503460f9495b8da/html5/thumbnails/18.jpg)
Obj. 7 Inflammatory response 1. Skin & mucous membranes 2. Phagocytic cells 3. Natural killer cells
4. Inflammatory response– damaged tissues release histamines– Histamines make vessels leaky,
releasing phagocytes & clotting factors– Phagocytes engulf bacteria– Platelets form clots

Obj. 5 Nonspecific Defenses: things your body uses to defend against ANYTHING
5. Antimicrobial substances– Interferon–Complement proteins
![Page 22: Immune System Day 3 Health can be squandered, but not stored up. Mason Cooley (b. 1927),](https://reader030.vdocument.in/reader030/viewer/2022032517/56649c9c5503460f9495b8da/html5/thumbnails/22.jpg)
Obj. 8 Fever 1. Skin & mucous membranes 2. Phagocytic cells 3. Natural killer cells 4. Inflammatory response 5. Antimicrobial substances
6. Fever– Macrophages release pyrogens– Hypothalamus elevates temperature– Liver & spleen supply less iron– Bacteria don’t grow well without iron– Metabolism increases speeding
repair.
