Study Notes
Lymphatic System and Immunology
- Edema occurs due to the absence or blockage of lymphatic vessels, leading to fluid accumulation in tissues.
- IgD is a class of immunoglobulin that functions as an antigen receptor on B cell surfaces.
- Plasma cells are the specific cell type responsible for antibody production.
- The cellular immune response is primarily mediated by activated T cells.
- The thoracic duct is a major lymphatic structure running along the posterior midline of the thoracic cavity.
Lymphatic Circulation
- T cells are crucial for initiating cellular immune responses.
- Lymph re-enters the bloodstream via the venous circulation.
- Complement proteins in plasma enhance inflammation, attract phagocytes, and promote phagocytosis.
Lymphatic Vessels and Function
- Lymph flows in lymphatic vessels from the bottom to the top, indicated by the position of valves.
- The remnant of the thymus is located in the thoracic region.
Immunoglobulin Classes
- Immunoglobulins present in secretions include IgA and IgE.
- Opsonization refers to the process of coating antibody-antigen complexes to facilitate phagocytosis by immune cells like macrophages and neutrophils.
Inflammation and Immune Response
- Inflammation represents the body's tissue response to injury or infection.
- Essential nutrients, required in the diet because the body cannot synthesize them adequately, include vitamins and minerals.
Digestive System
- Pepsin is the most vital digestive enzyme in gastric juice, beginning protein digestion when activated by hydrochloric acid.
- Dentin is the tooth structure that resembles bone but is denser and harder than bone.
Nutritional Compounds
- Beta-carotene serves as a precursor for vitamin A.
- The mucosa layer of the digestive tract consists of epithelial tissue and may include folds and mucus-secreting glands.
B Cells and T Cell Activation
- Activated B cells proliferate, resulting in a clone; some cells become plasma cells while others differentiate into memory cells.
- Antigen-presenting cells (APCs), such as macrophages, process foreign antigens and present them to T cells for activation.
Autoimmune Conditions
- Autoimmune diseases occur when the immune system mistakenly attacks the body's own cells.
- The mononuclear phagocytic system encompasses various cells, including macrophages, monocytes, and neutrophils.
