Lymphatic and Immune Systems
Chapter Outline
8.1 Lymphatic SystemThe lymphatic vessels form a one-way system, which transports lymph from the tissues and fat from the lacteals to certain cardiovascular veins. 146The lymphoid organs (red bone marrow, spleen, thymus, lymph nodes, and tonsils) play critical roles in defense mechanisms. 147 |
| | | 8.2 Nonspecific DefensesImmunity consists of nonspecific and specific defenses to protect the body against disease. 148Nonspecific defenses consist of barriers to entry, the inflammatory reaction, natural killer cells, and protective proteins. 148 |
| | | 8.3 Specific DefensesSpecific defenses require two types of lymphocytes: B lymphocytes and T lymphocytes. 150 |
| | | 8.4 Induced ImmunityInduced immunity for medical purposes involves the use of vaccines to achieve long-lasting (active) immunity and the use of antibodies to provide temporary (passive) immunity. 156 |
| | | 8.5 Immunity Side EffectsWhile immunity preserves life, it is also responsible for certain undesirable effects, such as allergies, autoimmune diseases, and tissue rejection. 1588.6HomeostasisThe lymphatic system works with the other systems of the body to maintain homeostasis. 160 s |
