Final answer:

Howell-Jolly bodies are the type of erythrocyte inclusion that measure approximately 5µm and are seen in certain hematologic conditions or after splenectomy.

Step-by-step explanation:

The type of erythrocyte inclusion that comprises approximately 5μm in size are Howell-Jolly bodies. Howell-Jolly bodies are nuclear remnants that are usually found in red blood cells following splenectomy or in certain hematologic conditions. A complete blood count and reticulocyte count can help identify them. However, in G6PD deficiency, Heinz bodies, which are denatured hemoglobin precipitates, can be seen on a blood film. These inclusions help in diagnosing certain conditions where the normal biconcave structure of red blood cells containing hemoglobin is altered. Erythrocytes, or red blood cells, lack a nucleus and most organelles in their mature form to maximize space for hemoglobin, which is crucial for oxygen transport.
