Trivia Questions On Red Blood Cell Morphology! Quiz - Quiz

Below are some Trivia Questions on Red Blood Cell Morphology! The red blood cells in the body are charged with transporting oxygen throughout the body and taking back carbon dioxide to the lungs so that it can be exhaled. How about you take up the quiz and see if you know how a normal red blood cell should look like.


Questions and Answers
  • 1. 

    Identify the name given to this RBC morphology. Please fill answer below

    Explanation
    An echinocyte is the name given to this RBC morphology. Echinocytes are characterized by their spiky appearance, with numerous small, evenly spaced projections extending from the cell surface. These projections give the RBC a crenated or "burr-like" appearance. Echinocytes can be caused by various factors such as certain medications, electrolyte imbalances, liver disease, or kidney disease.

    Identify the name given to this RBC morphology. Please fill answer below

    Explanation
    Target cells, also known as codocytes, are a type of red blood cell morphology characterized by a central bullseye-like area of hemoglobin surrounded by a clear ring. This gives the cell a target-like appearance when viewed under a microscope. Target cells can be seen in various conditions such as liver disease, iron deficiency anemia, thalassemia, and hemoglobinopathies. The name "target cells" is derived from their distinctive appearance.

    Identify the name of this RBC morphology. Please fill answer below

    Explanation
    A drepanocyte is a type of red blood cell (RBC) morphology that has an elongated, crescent or sickle shape. This abnormal shape is typically seen in individuals with sickle cell disease, a genetic disorder that affects the structure of hemoglobin in RBCs. Drepanocytes can cause blockages in blood vessels, leading to pain, organ damage, and other complications associated with sickle cell disease.

    Identify the name of this RBC morphology. Please fill answer below

    Explanation
    A keratocyte is a type of red blood cell (RBC) morphology characterized by a cell that appears to have two or more projections on its surface. These projections resemble horns or spurs, giving the cell a "horned" or "spurred" appearance. This morphology is often associated with certain diseases or conditions, such as liver disease or iron deficiency anemia.

  • 5. 

    Based on the size, what is the term used to describe this RBC? Please fill answer below

    Explanation
    The term "macrocytic" is used to describe an RBC that is larger than normal. This can be seen in conditions such as megaloblastic anemia, where the RBCs are larger due to impaired DNA synthesis. Macrocytic RBCs can also be seen in liver disease and alcoholism.

    What is the name given to this RBC morphology? Please fill answer below

    Explanation
    Spherocytes are a type of red blood cell morphology characterized by a smaller, rounder shape and lack of central pallor. This abnormal morphology is typically caused by a loss of membrane surface area, resulting in a more compact cell. Spherocytes are commonly seen in conditions such as autoimmune hemolytic anemia and hereditary spherocytosis. They can be identified on a blood smear by their dense, dark appearance and absence of the central pallor.

    Identify this RBC arrangement on a blood film. Please fill answer below

    Explanation
    Rouleaux formation refers to the stacking or clumping of red blood cells (RBCs) in a linear fashion, resembling a stack of coins. This arrangement occurs due to the presence of certain proteins or molecules on the surface of RBCs that cause them to adhere to each other. Rouleaux formation is a common phenomenon in blood films and can be seen in various conditions, such as inflammation, infections, and certain types of cancer. It is important to note that rouleaux formation is a normal physiological process and does not necessarily indicate any underlying pathology.

  • 8. 

    Identify these RBC inclusions. Please fill answer below

    Explanation
    Howell-Jolly bodies are small, round, basophilic inclusions found in red blood cells. They are remnants of the cell nucleus that should have been removed during the normal maturation process of red blood cells in the bone marrow. Howell-Jolly bodies are typically seen in conditions where there is increased turnover or decreased splenic function, such as after splenectomy or in certain hematological disorders. The presence of Howell-Jolly bodies in red blood cells can be identified through microscopic examination of a blood smear.
