What is the thin layer of tissue that forms the natural outer covering of the body of a person or animal?
What is skin?
What are the lymphoid tissues located at the back of the throat?
What are tonsils
What is the protective response by the body to injury or infection?
What is inflammation?
Which cell type provides "memory" of previous infections, enabling a faster and stronger immune response upon subsequent encounters?
What is a memory T cell?
What specialized immune cells that act as the body's "big eaters?"
What are macrophages
What structure is the moist, inner lining of some organs and body cavities?
What is the mucous membrane?
What structure's purpose is to include protection, sensation, temperature regulation, vitamin D production, and excretion?
What is skin?
What is a type of adaptive immunity that relies on antibodies, produced by B cells?
What is a humoral response?
Which type of cell activates an immune response?
What are Helper T cells?
What cell is crucial for long-term immunity because it provides a rapid and robust antibody response upon re-exposure to a specific antigen?
What are memory B Cells
What are crucial for coordinating the body's immune response by educating, multiplying, and activating immune cells to fight disease?
What are lymph nodes?
What are the specialized tissues that line body cavities and passages that open to the outside?
What are Mucous Membranes?
What is an immune response that does not rely on antibodies, but instead involves the activation of various immune cells to fight off infections or other threats?
What is a cell-mediated response?
Which type of cell produces Y-shaped antibodies and recognizes specific antigens?
What are memory B cells?
Which cells are T lymphocytes that remember previous encounters with specific antigens
What are memory T Cells
What is a fist-sized organ in the upper left abdomen, under the rib cage, and is part of the lymphatic and immune systems?
What is the spleen?
What is a Y-shaped protein, also known as an immunoglobulin, produced by the immune system to recognize and neutralize foreign substances called antigens?
What are antibodies?
What is the engulfing material from the extracellular space to within the cell?
What is phagocytosis?
What is a type of white blood cell (leukocyte) that plays a crucial role in the immune system?
What are lymphocytes?
What type of immune cells surround and kill microorganisms, ingest foreign material, and remove dead cells?
What are phagocytes?
What stops germs from entering the body through the mouth or the nose?
What are tonsils?
What are proteins, found on the surface of cells, viruses, bacteria, and other foreign substances, that trigger an immune response?
What are antigens?
What are the two types of inflammation?
What is acute and chronic inflammation?
What are the large, specialized white blood cells of the innate immune system that act as the body's first responders to infections and tissue damage?
What are macrophage cells?
What are the 3 types of lymphocytes?
What are B cells, T cells, and NK cells
