What is a lymph node?
A small bean-shaped structure that is part of the body's immune system. They filter substances that travel through the lymphatic fluid.
What is the Immune System?
Your body's complex defense mechanism
These long-lived B cells are vital in immunological memory, enabling the immune system to respond more rapidly to previously encountered antigens.
What are memory B cells?
This organ, often referred to as the body's first line of defense, consists of multiple layers and is involved in the synthesis of vitamin D.
What is the skin?
The process by which the body's immune system learns to recognize and remember specific pathogens.
What is immunological memory?
What are antigens?
A toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies.
a process where phagocytes, specialized immune cells, engulf and eliminate foreign particles, such as bacteria, viruses, and dead cells, from the body.
what is Phagocytosis?
This class of white blood cells, critical to adaptive immunity, are characterized by their ability to undergo clonal expansion in response to specific antigens.
What are lymphocytes?
These epithelial surfaces, rich in goblet cells, serve as a protective barrier while also facilitating the movement of foreign particles out of the body.
What are mucous membranes?
This type of blood cell is crucial for transporting oxygen throughout the body.
What are red blood cells?
What are lymphocytes?
A form of small leukocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system.
an immune system response that doesn't rely on antibodies, but instead uses specialized immune cells like T cells and macrophages to directly attack and eliminate pathogens or infected cells.
what is a Cell-mediated response?
These T cells play a pivotal role in activating other immune cells and are characterized by the CD4 receptor on their surface.
What are helper T cells?
This lymphatic organ not only filters blood but also serves as a reservoir for red blood cells and participates in the immune response by producing immune cells.
What is the spleen?
The body's largest organ, which acts as a barrier to protect against infection and regulates temperature.
What is skin?
What are phagocytes?
A type of cell within the body capable of engulfing and absorbing bacteria and other small cells and particles.
What causes inflammation?
triggered by various factors, including pathogens, tissue damage, and exposure to toxins.
These T cells are crucial for the elimination of previously encountered pathogens or infected host cells, possessing the ability to recognize specific antigens and mount a swift response.
What are memory T cells?
These lymphoid tissues, strategically located in the pharyngeal region, play a crucial role in the immune response by capturing pathogens entering through the mouth and nose.
what are tonsils?
This hormone, produced by the pancreas, helps regulate blood glucose levels
What is insulin?
What are macrophages?
A type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells.
a type of adaptive immunity that relies on antibody molecules, specifically immunoglobulin proteins, to defend against extracellular pathogens and toxins.
what is the Humoral response?
These versatile immune cells can ingest and digest a wide range of pathogens, including bacteria and viruses, and serve as a bridge between innate and adaptive immune responses.
What are phagocytes?
This complex protein structure, produced by plasma cells, is critical for neutralizing toxins and marking pathogens for destruction by other immune cells.
What are antibodies?
This part of the autonomic nervous system is responsible for the "fight or flight" response.
What is the sympathetic nervous system?
