NEET BIOLOGY

Detailed explanation-1: -Basophils are a type of white blood cell that works closely with your immune system to defend your body from allergens, pathogens and parasites. Basophils release enzymes to improve blood flow and prevent blood clots.

Detailed explanation-2: -So, the correct answer is ‘Basophil’.

Detailed explanation-3: -When activated, basophils degranulate to release histamine, proteoglycans (e.g. heparin and chondroitin), and proteolytic enzymes (e.g. elastase and lysophospholipase).

Detailed explanation-4: -Basophils migrate to injury sites and cross the capillary endothelium to accumulate in the damaged tissue, where they discharge granules that contain histamine (dilates blood vessels) and heparin (prevents clotting).

Detailed explanation-5: -Basophils are one of the five white blood cell types that protect your body from infections or respond to intruders like parasites, fungi and cancer cells. Basophils drive your body’s reaction to allergens. They’re why you sneeze, cough or have a runny nose during allergy season or anytime you encounter an allergen.
