We reviewed flashcards then took a vocabulary test on Unit 8 The Human Body Chapter 35 Immune System and Disease.

We went over Packet A 35.3 Fighting Infectious Disease and 35.4 Immune System Disorders. Then we reviewed infectious diseases and defenses against diseases.

35.4 Immune System Disorders – We learned about the consequences when the immune system does not function properly. We discovered that taking medications that suppress the immune response will put a person at greater risk of contracting infectious diseases due to their overall immune response being weakened.

35.4 Immune System Disorders – We learned how a strong immune response to harmless antigens can produce allergies, asthma, and autoimmune disease. When the immune system attacks the body’s own cells, it produces an autoimmune disease such as diabetes, arthritis, and lupus. We learned about the discovery of acquired immunodeficiency syndrome or AIDS.
Assignment: Work on Packet A 35.4 Immune System Disorders.

35.3 Fighting Infectious Disease – We learned how vaccinations work by stimulating the immune system with antigen. The immune system produces memory B cells and memory T cells that quicken and strengthen the body’s response to repeated infection. We learned the difference between active and passive immunity.

35.3 Fighting Infectious Disease – We learned how English physician, Edward Jenner, deliberately injected cowpox disease which protected people from smallpox by building up immunities to fight the disease. We discovered how vaccines and externally produced antibodies fight disease. We learned how in 1900 more than 30% of deaths were caused by infectious disease, but in 2005 less than 5% of deaths were caused by infectious disease. This is due to public health measures dedicated to monitoring and regulating food and water supplies as well as vaccinations.
