a. ___
b. ___

d. ___
e. ___

Verified step by step guidance

1. Step 1: Understand the five main types of white blood cells (WBCs), also known as leukocytes. These are neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Each has distinct morphological features visible under a microscope.
2. Step 2: Examine the characteristics of each WBC type in the photographs. For example, neutrophils typically have a multi-lobed nucleus and fine granules; lymphocytes have a large, round nucleus with little cytoplasm; monocytes are larger with a kidney-shaped nucleus; eosinophils have bi-lobed nuclei and large red-orange granules; basophils have large dark blue or purple granules that often obscure the nucleus.
3. Step 3: Match each photograph (a, b, c, d, e) to the WBC type by comparing the visible features in the images to the known characteristics of each cell type.
4. Step 4: Label each photograph accordingly with the identified WBC type: neutrophil, lymphocyte, monocyte, eosinophil, or basophil.
5. Step 5: Review your identifications by cross-checking the morphological features and ensuring that each WBC type is assigned to only one photograph, as there are five types and five images.

Key Concepts

Types of White Blood Cells (Leukocytes)

White blood cells are immune cells that protect the body against infections. The five main types are neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with distinct functions and appearances. Recognizing these types is essential for identifying them in microscopic images.

Morphological Characteristics of White Blood Cells

Each white blood cell type has unique features such as nucleus shape, cytoplasm color, and granule presence. For example, neutrophils have multi-lobed nuclei, eosinophils contain red-orange granules, and lymphocytes have large, round nuclei. Understanding these traits aids in accurate identification.

Staining Techniques in Hematology

Blood smears are stained using dyes like Wright or Giemsa stain to highlight cell structures. These stains color different cell components distinctly, making it easier to differentiate white blood cell types under a microscope. Familiarity with staining effects is crucial for interpreting images.
