Study Notes
Leukocytes
- Neutrophils are the most abundant type of leukocyte, playing a critical role in immune response.
- Granular leukocytes include eosinophils, basophils, and neutrophils, which have granules in their cytoplasm.
Erythrocytes
- Red blood cells, also known as erythrocytes, are anucleate, meaning they lack a nucleus.
- These cells contain hemoglobin, which is essential for oxygen transport throughout the body.
Phagocytic Cells
- Monocytes and neutrophils are actively phagocytic leukocytes, capable of engulfing and digesting pathogens and debris.
Agranular Leukocytes
- Agranular leukocytes consist of monocytes and lymphocytes, which lack visible granules in their cytoplasm.
Platelets
- Megakaryocytes are large bone marrow cells that fragment to form platelets, essential for blood clotting.
Formed Elements
- Formed elements of blood include various cell types, such as erythrocytes, leukocytes, and platelets, essential for multiple functions in the circulatory system.
Eosinophils
- Eosinophils increase in response to allergy attacks, playing a crucial role in the body's allergic reactions and responses to parasitic infections.
Basophils
- Basophils release histamine during inflammatory reactions, contributing to the body’s response to allergens and promoting blood flow to tissues.
Lymphocytes
- After originating in the bone marrow, lymphocytes may also mature in lymphoid tissue, and are vital for adaptive immunity.
Plasma
- Plasma is the non-cellular, fluid matrix of blood, primarily composed of water and essential for transporting nutrients, hormones, and waste products.
Monocytes
- Monocytes increase in number during prolonged infections, providing long-term defense against pathogens.
Basophils
- Basophils are the least numerous type of leukocyte and play a role in allergic reactions and inflammation.
White Blood Cells
- The term "white blood cells" encompasses all types of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils.
