Red Blood Cell Function and Characteristics Quiz

Which shape should a normal red blood cell have?

What is the significance of the central pallor in red blood cells?

What is the term for red cells with a central pallor occupying more than 30-45% of the cell diameter?

Which of the following conditions is NOT associated with hypochromic red cells?

What is the term for red cells with an increased hemoglobin content?

Which of the following is NOT associated with hypochromic red cells?

What is the term for red cells with a central pallor occupying less than 30-45% of the cell diameter?

What are the possible causes of elongation or pointy structures in red blood cells?

What is the term for red cells with an increased hemoglobin content?

What is the significance of the circular disc shape of a normal red blood cell?

A normal red blood cell should have a biconcave disc shape.
The central pallor in red blood cells is a lighter area in the center of the cell, signifying the absence of hemoglobin in that region.
Hypochromic red cells are red blood cells with a central pallor occupying more than 30-45% of the cell diameter. This indicates a reduced hemoglobin content in the cell.
Hyperchromic red cells are red blood cells with an increased hemoglobin content. This means the central pallor is smaller than 30-45% of the cell diameter.
Elongation or pointy structures in red blood cells can be caused by several factors, including:
- Spherocytosis: A condition where red blood cells are spherical instead of biconcave.
- Sickle cell anemia: A genetic disorder that causes red blood cells to become sickle-shaped.
- Iron deficiency anemia: A condition caused by a lack of iron in the body.
The circular disc shape of a normal red blood cell is important for its function. It allows for a larger surface area for oxygen exchange, and its flexibility allows it to navigate through narrow capillaries.
