Which Feature of WBCs Makes Them Particularly Important in Tissue

Question

Which feature of WBCs makes them particularly important in tissue injury?
A) They undergo aerobic respiration.
B) They stick to injured blood vessels.
C) They undergo a fast rate of mitosis.
D) They can squeeze out through blood vessel walls into tissues.
E) They carry loads of oxygen.

Accepted Answer

White blood cells (WBCs) can squeeze out through blood vessel walls into tissues, making them particularly important in tissue injury. This process is called diapedesis or extravasation. When tissues are injured, WBCs migrate to the site of injury to help fight off infection and promote healing.
