"Eosinophils" Natural Recordings by Native Speakers
Eosinophils are a type of white blood cell that plays a key role in the human body's defense against parasitic infections and in the allergic response. Eosinophils are produced in the bone marrow and circulate in the blood, where they can be activated by various inflammatory stimuli, such as the presence of allergens or parasites. When activated, eosinophils release enzymes and other chemicals that help to neutralize these foreign substances and remove them from the body. Eosinophils are often elevated in conditions such as allergies, asthma, and parasitic infections, and may also be present in conditions such as rheumatoid arthritis and certain types of cancer.
