In which leukocyte do the granules make the nucleus difficult to visualize.

Step 1
- Leukocytes, or white blood cells, are classified into several types based on their structure and function. One type that contains granules is the granulocytes, which include neutrophils, eosinophils, and basophils. Show more…

Match the following leukocytes with the correct description of their appearance Lymphocyte Monocyte Neutrophil Basophil Eosinophil 1. Nucleus highly variable with multiple lobes, often fragmented 2. Red staining cytoplasmic granules 3. largest of the leukocytes, nucleus often horseshoe shaped 4. Least common of the granulocytes 5. Nucleus takes up most of the cell area, very little cytoplasm visible

Neutrophil - These cells have faint light pink granules in the cytoplasm and a characteristic lobulated nucleus. The more mature the neutrophil the more lobes you will find. These cells circulate in the blood and their primary job is phagocytosis (eating bacteria or viruses) at the site of a wound. They are usually short lived but make up 60 to 70% of the leukocyte population. Lymphocyte - These cells have a characteristic circular nucleus which stains dark and very little cytoplasm which stains light. These cells are lack granules. Lymphocytes collectively make up both T and B cells of the immune system. These cells are responsible for the specific immune response and the production of antibodies against a specific invading pathogen. B lymphocytes are responsible for the production of antibodies and T cells have two functions. T helper cells activate B cell and T killer cells. T killer cells attack and kill invading fungal cells, virally infected cells, and cancer cells. Monocyte - These are large cells ranging up to 15 micrometers. They have a characteristic kidney bean shaped nucleus which stains dark with a light cytoplasm. These cells do not stay in the blood. They usually migrate out of the blood into specific tissues such as the brain, liver, pancreas and lung where they become macrophages. Their primary job is phagocytosis. These cells mop up much of the cell debris and pus left behind from an active infection. These cells also form special connections with T cells during the production of a specific immune response. Eosinophil - These cells are characterized by bright pink cytoplasmic granules in the cytoplasm and a bi-lobed nucleus. The entirety of their function is not known; however, they are important in the fight against parasitic infections. The granules contain destructive enzymes which, when released at the site of an invading organism, cause extensive damage. Other functions are still under investigation.
