Military use of biological weapons “Biological weapons amount to no more than “weapons of mass disruption” (Introduction to Biological Weapons). Biological weapons are toxic materials taken from pathogens (bacteria)‚ host or target. These can be put in something as simple as a letter‚ in an envelope‚ or something as complex as a missile containing the materials inside. The military should not use biological weapons because the U.S. doesn’t have the funds to protect the country‚ they are

but some are and can make us sick. These bacteria are called Pathogens. Pathogens can cause diseases in animals and plants. Some examples of pathogens are leprosy‚ food poisoning‚ pneumonia‚ tetanus‚ and typhoid fever. Fortunately‚ we have antibiotics we can take which help to fight off the bad pathogens. We also have antiseptics to help us keep wounds clean of bacteria and antibiotic soap we use to wash to help keep off bad pathogens. Remember to wash your hands! Are bacteria all bad?

Chapter 16-Lymphatic System & Immunity 1. Explain the functions of the lymphatic system. The lymphatic system functions to balance fluid‚ lipid absorption (via lacteals=lymph capillaries) and defense. It removes toxins/pathogens‚ fight infections and transports excess fluid in the interstitial spaces and returns it to the blood stream. Lacteals absorb digested fats from small intestines and transports it to venous circulation. 2. Trace the general pathway of lymph from the interstitial

(10 pt) Pieces of pathogens (particularly pieces of viruses) do dsRNA interact with TLR-3. Because the pathogens (viruses) are destroyed into pieces in the endosome‚ after they are destroyed‚ they are mainly nucleic acid

lymphatic organs that contain lymphoid tissues. Lymphatic vessels are structures that absorb fluid that diffuses from blood vessel capillaries into surrounding tissues. Lymphatic vessels transport lymph to lymph nodes. These structures filter lymph of pathogens‚ such as bacteria and viruses. Lymph nodes also filter cellular waste‚ dead cells‚ and cancerous cells. The thymus gland is the main organ of the lymphatic system. Its primary function is to promote the development of specific cells of the immune
