Question | Answer |
Lymph tissue | Groups of lymphocytes and other cells which support the lymphocytes |
Lymph nodes | Encapsulated masses of lymph tissue found along lymph vessels |
Lymph | Watery fluid formed from interstitial fluid and found in lymph vessels |
Edema | A buildup of excess fluid in the tissues, which can lead to swelling |
Immunological defense | The process by which the body protects itself from pathogenic invaders such as bacteria, fungi, parasites, and foreign substances |
Diffuse lymphatic tissue | Concentrations of lymphatic tissue with no clear boundaries |
Lymph nodules | Lymphatic tissue arranged into compact, somewhat spherical structures |
Innate immunity | An immune response that is the same regardless of the pathogen or toxin encountered |
Acquired immunity | An immune response targeted at a specific pathogen or toxin |
Complement | A series of 20 plasma proteins activated by foreign cells or antibodies to those cells. They (1) lyse bacteria, (2) promote phagocytosis, and (3) promote inflammation. |
Interferon | Proteins secreted by cells infected with a virus. These proteins stimulate nearby cells to produce virus-fighting substances. |
Pyrogens | Chemicals which promote fever by acting on the hypothalamus |
Humoral immunity | Immunity which comes from antibodies in blood plasma |
Cell-mediated immunity | Immunity which comes from the actions of T-lymphocytes |
interstitial fluid | fluid that exists between the cells |
tonsils | groups of lymph nodules found in the throat and on the back of the tongue |
Peyer's patches | groups of lymph nodules found in the wall of the small intestine |
afferent lymph vessels carry blood ________ the lymph node | into |
efferent lymph vessels carry lymph ________ the lymph node | away from |
____________________ functions are 1) testing the lymph for foreign invaders 2) adding lymphocytes to the blood 3) be a reservoir of oxygen-rich blood | lymph node |
____________________ functions are 1) cleanse the blood of foreign invaders 2) adding lymphocytes to the blood 3) filtering the lymph with macrophages | spleen |
The ______________ 1) is where T-lymphocytes mature 2) secretes thymosin | thymus |
constant region | section of the antibody that determines what groups it is in |
_________________ can inactivate antigens by binding to them, binding them together in groups, activating complement, stimulating phagocytosis, and stimulating inflammation | antibodies |
________________ release antibodies | plasma B-cells |
________________ remember the infection so that they can respond to the next infection | memory B-cells |
________________ attack and lyse foreign cells | cytotoxic T-cells |
memory T-cells | remember the infection for the next time |
_______________ promote the proliferation of cytotoxic T-cells and B-cells | helper T-cells |
MHC | a group of glycoproteins that identifies cells as part of the body |
variable region | section of the antibody that determines what antigen it can bind to |
vasodilation | result of inflammation which causes increased blood flow |
