Study Notes
Erythrocytes and Oxygen Demand
- Increased oxygen demand in athletes correlates with higher red blood cell (RBC) counts.
- Abnormal erythrocyte characteristics, such as size, shape, and staining properties, serve as critical disease indicators.
Leukocytes Overview
- Leukocytes originate in the bone marrow and are released continuously into the bloodstream.
- Primary function occurs outside blood vessels, primarily in loose connective tissue.
- Acts as a mobile defense force against bacteria, viruses, parasites, toxins, and tumor cells.
Types of Leukocytes
- Five types of leukocytes classified into two categories based on nuclear shape and presence of cytoplasmic granules:
- Granulocytes: Characterized by a single or multi-lobed nucleus.
- Neutrophils, eosinophils, and basophils.
- Agranulocytes: Lymphocytes (T cells and B cells) and monocytes.
- Granulocytes: Characterized by a single or multi-lobed nucleus.
Granulocyte Details
-
Neutrophils:
- Function primarily in bacterial defense through phagocytosis.
- Contain both primary (azurophilic) and secondary (specific) granules.
- Myeloperoxidase enzyme plays a significant role in bactericidal activity.
-
Eosinophils:
- Larger cells with specific granules that stain blue.
- Involved in combating parasitic infections and modulating allergic reactions.
-
Basophils:
- Characterized by large dark granules containing histamine.
- Play a role in inflammatory responses and allergic reactions.
Lymphocyte Functionality
-
B Lymphocytes: Differentiate into plasma cells that produce antibodies.
-
T Lymphocytes: Develop in the thymus and are crucial for adaptive immunity.
- Thymus involvement distinguishes T cell function from B cells.
-
Memory Cells: Enable a faster immune response upon re-exposure to the same antigen.
-
Suppressor T Cells: Regulate the immune response, preventing overactivity, and can lead to autoimmune diseases if damaged.
Immune Response Mechanism
- Activation of immune cells is prompt when encountering pathogens, allowing for an efficient defense system.
- The differentiation and specialized roles of lymphocytes enhance the body’s capacity to respond to infections.
