Step by step
Solved in 2 steps
- Phagocytes transmit information to the lymphocytes B cells and helper T cells produce special protein called_____________ antibodies blood leukocytes long-term macrophages_____ _____ _____ are specialized lymphocytes thatsecrete perforins to lyse cell membranes of virus-infectedcells.The endothelial cells found closest to the site of an infection express proteins called lectins. Each lectin binds to a particular ____________ that is presented on the surface of a target cell.
- Which of the following cells is not phagocytic? Langerhan cell Monocyte Chondroblast Dendritic cellThe function of Th lymphocytes at the immunological synapse is to __________. View Available Hint(s) for Part A strengthen the synapse eliminate the synapse limit the synapse remember the synapseCytokines are released by phagocytes to initiate inflammation and ____________. attract more of other phagocytes interfere with chemotaxis engulf microbes attach to the cell surface for phagocytosis more than one of these additional functions none of these- it is only for inflammation
- Each B-lymphocyte has several hundred thousand identical copies of __________________ on their cell membranes.Phagocytes are drawn to the area of cell damage by histamine by a process called ___.All cells contain packets of a chemical called __________ which is released into the tissues when the cell is injured. This chemical is responsible for many of the features of inflammation
- Natural killer cells are part of ______________ immunity. adaptive innateComponents of plasma that will increase the phagocytosisLymphocytes that develop immunocompetence in the thymus are __________lymphocytes. We put everything in our mouth since our childhood. Therefore our mouth is full of live bacteria. These bacteria are potentially dangerous if they cross our gut wall into our blood circulation. Fortunately we are protected from them by our gut's mucosal lining and the cells (macrophages, dendritic cells, B and T lymphocytes) in the lymphoid tissue called [a] (enter two words). This structure play a crucial role for the development of food tolerance or food [b] (enter one word), coeliac disease and chronic inflammatory bowel disease.
