what is a white blood cell that squeezes through capillary walls to reach an infection site? diapedesis
what is the process by which the white blood cells engulf and digest the bacteria called? phagocytosis
the reaction that restricts the spread of infection; promoted by basophils, by secretion of heparin and histamine; involves swelling and increased capillary permeability is called …………………… (inflammatory response)
damaged cells release chemicals that attract leukocytes. this phenomenon is called …………………… (positive chemotaxis)

Explanation:

• Diapedesis: White blood cells squeeze through capillary walls to reach infection sites.
• Phagocytosis: Process of white blood cells engulfing and digesting bacteria.
• Inflammatory response: Reaction restricting infection spread, promoted by basophils (secreting heparin and histamine), involving swelling and increased capillary permeability.
• Positive chemotaxis: Damaged cells release chemicals attracting leukocytes.

Answer:

• Diapedesis
• Phagocytosis
• Inflammatory response
