Identify red blood cells, neutrophils, eosinophils, basophils, platelets, monocytes, and lymphocytes under the microscope; Perform Wright’s stain of a blood smear. Conduct a differential blood count to determine the percentage of various leukocytes in blood.
Your blood will always be red, and the liquid is not just a liquid, as it also has some basic building blocks called cells. If you zoom even further using a microscope, you’ll be able to see other components, such as ions and macromolecules.
The different components that make up blood. Plasma, white blood cells, red blood cells, platelets.
microscope. Human blood contains many different components, from white blood cells to platelets, but the most abundant component by far are red blood cells. More properly known as erythrocytes, red blood cells make up 70% of an adult human’s cells by count.
Using a special histological staining method (Wright’s Stain), leukocytes can be seen under a microscope. This stain includes azure B to stain the granules in the cytoplasm of white blood cells so that they can be differentiated.
If the blood film is properly prepared and stained, we should be able to easily see individual cells under a bright-field microscope. You can use the characteristics we mentioned above and the examples below to identify each type of leukocytes.
Neutrophils are the commonest type of white blood cell found in a blood smear. They make up 60-70% of the total amount of white blood cells. Neutrophils have 3 types of granules: azure granules (lysosomes), secretory granules in salmon pink cytoplasm, anti-microbial enzymes. have glycoproteins and gelatinase. Function:
