Diapedesis and Leukocytes Quiz

White Blood Cells and Their Functions

• Diapedesis is the ability of leukocytes (white blood cells) to move out of capillaries into surrounding tissues.
• Neutrophils primarily function to phagocytize bacteria and other pathogens, playing a crucial role in the innate immune response.
• Monocytes, which differentiate into macrophages, are the largest of all white blood cells and are vital for immune defense.

Inflammation and Basophils

• Basophils release histamine and other mediators that contribute to the inflammatory response, promoting blood flow and attracting other immune cells to sites of infection or injury.

Lymphocytes and Monocytes

• Lymphocytes and monocytes are both types of white blood cells, with lymphocytes primarily involved in adaptive immunity and recognizing specific antigens, and monocytes functioning in phagocytosis and antigen presentation.

Blood Clotting and Prothrombin

• Prothrombin is a plasma protein that plays a crucial role in blood coagulation as a precursor to thrombin, which is essential for clot formation.
• Prothrombin activator converts prothrombin into thrombin within the clotting cascade, initiating the process of converting fibrinogen into fibrous strands that form a clot.

Erythropoiesis

• Erythropoiesis is the process of producing red blood cells (erythrocytes) from stem cells in the bone marrow.
• Erythropoiesis takes place primarily in the red bone marrow of adults, with some activity in the liver and spleen in fetal development.
• The formation of a mature red blood cell typically takes about 7 days.
