What is diapedesis, and which type of blood cells primarily use this process?
A
The process of platelet aggregation; used by thrombocytes
B
The transport of oxygen in the bloodstream; used by hemoglobin
C
The movement of white blood cells through capillary walls; used by leukocytes
D
The movement of red blood cells through capillary walls; used by erythrocytes
Verified step by step guidance1
Understand the term 'diapedesis': Diapedesis is the process by which cells move through the walls of capillaries into surrounding tissues.
Identify the type of cells involved: Diapedesis is primarily used by white blood cells, also known as leukocytes.
Recognize the function of leukocytes: Leukocytes are involved in the immune response, and their ability to move through capillary walls allows them to reach sites of infection or injury.
Differentiate from other processes: Diapedesis is not related to platelet aggregation (used by thrombocytes) or oxygen transport (used by hemoglobin in red blood cells).
Conclude with the correct association: Diapedesis is specifically the movement of white blood cells through capillary walls, a critical function for immune surveillance and response.
