Blood

Granulocytes

White blood cells with granules in cytoplasm.

Phagocytic

Ability to engulf foreign particles and pathogens.

Erythrocytes

Red blood cells, carry oxygen via hemoglobin.

Leukocytes

White blood cells, crucial for immune response.

Agranulocytes

White blood cells without granules in cytoplasm.

Monocytes

Largest white blood cells, develop into macrophages.

Lymphocytes

Involved in immune responses, include T and B cells.

Thrombocytes

Platelets, smallest blood cells, initiate clotting.

Erythropoiesis

Process of making red blood cells in marrow.

Hemoglobin

Protein in RBCs that binds oxygen.

Thrombus

Blood clot formed at injury site.

Embolus

Dislodged thrombus that can block blood flow.

Plasma

Liquid part of blood, 90% water.

Albumins

Proteins that maintain osmotic pressure in blood.

Globulins

Proteins that produce antibodies for immune defense.

Fibrinogen

Plasma protein crucial for blood clotting.

Blood Clotting

Process to stop bleeding via clot formation.

Thromboplastin

Protein released by platelets to initiate clotting.

Prothrombin

Plasma protein converted to thrombin during clotting.

Thrombin

Enzyme converting fibrinogen to fibrin threads.

Fibrin Threads

Form mesh to seal wounds during clotting.

Blood Types

Classifications based on antigens on RBCs.

Type A Blood

Has A antigens, produces anti-B antibodies.

Type B Blood

Has B antigens, produces anti-A antibodies.

Type AB Blood

Has both A and B antigens, no antibodies.

Type O Blood

No antigens, produces both anti-A and anti-B antibodies.

Rh Factor

Antigen determining positive or negative blood type.
