This example tells us that Priyanka is informed that she has the bone disorder myelodysplastic syndrome, and she needs a blood transfusion. Based on this information, what type of bone marrow do you think is affected in myelodysplastic syndrome? And explain your reasoning. Alright. Based on this information, there's not a lot of information present.

There's myelodysplastic syndrome, and she needs a blood transfusion. Myelodysplastic, that's a complex word. I'm not going to worry about what it means or how to break it down because we have this information about a blood transfusion, which is significant. To remind ourselves of this, we have a femur depicted over here on the right. This picture shows a femur at the epiphysis, which is colored red to represent red marrow. Out of this, an arrow points out that all these different types of blood cells—red blood cells, white blood cells, and platelets—are produced there.

In contrast, the diaphysis is portrayed in yellow, indicating yellow marrow, and there we have adipose tissue or storage of fat triglycerides. Just knowing this, knowing that someone needs a blood transfusion, it indicates it must be related to the red marrow. So, I'm going to write down red marrow, and my reasoning is that the condition concerns blood. Of course, not all blood conditions have to deal exclusively with red marrow, but if it pertains to the type of marrow being affected, it's likely to do with the red marrow.

Myelodysplastic syndrome is actually a group of disorders that affect the proper development of blood cells. With that, we have more practice problems to follow, and I'll see you there.
