Basophils<\/strong>.<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<p>In a blood sample, the various types of leukocytes (white blood cells) each play distinct roles in the immune response. Understanding their relative abundance helps in diagnosing and managing various health conditions. Here\u2019s a breakdown of each type listed and their typical percentage in a blood sample:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Neutrophils<\/strong>: These are the most abundant type of white blood cells, constituting approximately 55-70% of the total leukocytes in the blood. Neutrophils are crucial in the body\u2019s defense against bacterial infections. They are the first responders to microbial infection and are characterized by their ability to perform phagocytosis, which involves engulfing and digesting pathogens.<\/li>\n\n\n\n<li><strong>Eosinophils<\/strong>: These white blood cells account for about 1-4% of the total leukocytes. Eosinophils are primarily involved in combating parasitic infections and modulating allergic responses. Their numbers can increase in conditions such as asthma and certain skin disorders.<\/li>\n\n\n\n<li><strong>Monocytes<\/strong>: Monocytes make up about 2-8% of the white blood cell count. They are involved in phagocytosis as well but have a longer lifespan compared to neutrophils. Once they migrate from the bloodstream into tissues, they differentiate into macrophages, which play a key role in the immune system by removing dead cells and pathogens.<\/li>\n\n\n\n<li><strong>Basophils<\/strong>: Basophils usually account for the smallest percentage of leukocytes, typically less than 1% of the total white blood cell count. They are involved in inflammatory reactions, especially those related to allergies, by releasing histamine and heparin. Despite their critical role in modulating immune responses and inflammation, their low abundance in the blood reflects their more specialized and localized function compared to other leukocytes.<\/li>\n<\/ol>\n\n\n\n<p>In summary, basophils are the least common type of white blood cells in a typical blood sample, making them the smallest percentage compared to neutrophils, eosinophils, and monocytes. Their role in the immune system is crucial but less frequent in general circulation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following usually accounts for the smallest percentage of leukocytes in a blood sample?
