Composition and Function of Blood

Components and Functions of Blood

Blood is a specialized form of connective tissue consisting of blood cells and plasma.

  • Blood cells
  • Plasma
  • Connective tissue
  • Extracellular matrix
  • Serum
  • Clotting factors
  • Coagulation cascade
  • White blood cells
  • Leukocytes
  • Erythrocytes
  • Platelets
  • Thrombocytes
  • Hemoglobin
  • Erythropoiesis

Sickle Cell Anemia and Spherocytosis

Leucocytes, Thrombocytes, and Hematopoiesis

Characteristics of Granulocyte White Blood Cells

Leucocytes originate in the bone marrow and include granulocytes such as neutrophils, eosinophils, and basophils which contain cytoplasmic granules.

  • Leucocytes
  • Granulocytes
  • Agranulocytes
  • Neutrophils
  • Eosinophils
  • Basophils
  • Phagocytic
  • Cytoplasmic granules
  • Nuclear lobes
  • Histamine
  • Allergic reactions
  • Parasitic infections
  • Inflammation

Characteristics and Functions of Agranulocytes

Agranulocytes include lymphocytes and monocytes which differentiate into specialized cells like plasma cells, T cells, B cells, macrophages, dendritic cells, and osteoclasts.

  • Agranulocytes
  • Lymphocytes
  • T cells
  • B cells
  • Plasma cells
  • Antibodies
  • Monocytes
  • Macrophages
  • Dendritic cells
  • Antigen-presenting cells
  • Osteoclasts
  • Osteoblasts
  • Bone marrow

Hematopoiesis and Blood Cell Formation

This topic covers hematopoiesis, including blood cell differentiation from hematopoietic stem cells and the roles of red and yellow bone marrow.

  • Hematopoiesis
  • Thrombocytes (Platelets)
  • Megakaryocytes
  • Hematopoietic stem cells (HSCs)
  • Red bone marrow
  • Yellow marrow
  • Blood cell differentiation
  • Granular leukocyte lineage
  • Lymphocyte lineage
  • Yolk sac
