Multiple Choice

What is diapedesis, and which type of blood cells primarily use this process?

The process of platelet aggregation; used by thrombocytes

The transport of oxygen in the bloodstream; used by hemoglobin

The movement of white blood cells through capillary walls; used by leukocytes

Verified step by step guidance

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.
