"Granulomas" Natural Recordings by Native Speakers
Granulomas are small clusters of immune cells, typically consisting of macrophages and lymphocytes, that accumulate at the site of inflammation or infection in response to injury or disease. They form in response to the presence of foreign particles, such as bacteria, fungi, or parasites, and help to contain and eliminate the invading organisms. Granulomas can be seen in tissues such as lungs, skin, and liver, and are often a characteristic feature of chronic inflammatory diseases, including tuberculosis, leprosy, and sarcoidosis.
Granulocytes are a type of white blood cell (leukocyte) characterized by the presence of granules in their cytoplasm. They play a vital role in fighting infections, such as bacterial infections, by engulfing and digesting foreign particles and microorganisms. There are three main types of granulocytes: neutrophils, eosinophils, and basophils. They can be identified by their distinct staining patterns and functions.
