2A Multipotent Haematopoietic Stem Cell (Hemocystblast) can differentiate to form two types of common progenitor stem cells:

- Amacrophages
13Which bony aspect of the hip is the most common site for bone marrow aspiration?
The [blank_start]posterior iliac crest[blank_end]- Aposterior iliac crest
14Which aspect of the iliac crests, anterior or posterior, is the most common site for bone marrow aspiration?
The [blank_start]Posterior[blank_end] Iliac Crests- APosterior
15A bone marrow biopsy is also commonly called a [blank_start]trephine[blank_end] biopsy due to the surgical instrument used to conduct the procedure, which has a cylindrical saw used for removing a disk of bone.
- Atrephine
16Red blood cells have large, single nuclei.

18Foetal Haemoglobin consists of two [blank_start]alpha[blank_end] chains and two [blank_start]gamma[blank_end] chains
- Aalpha
- Bdelta
- Cgamma
- Dbeta
19[blank_start]Gamma[blank_end] chains allow a higher affinity for oxygen as they do not interact as well with 2,3-DPG
- AGamma
- BAlpha
- CBeta
- DDelta
20[blank_start]Fe3+[blank_end] = Oxidised form of iron
[blank_start]Fe2+[blank_end] = Reduced (non-oxidised) form of Iron- AFe3+

24Which organ conjugates bilirubin?
The [blank_start]Liver[blank_end]- ALiver
25Bilirubin is excreted within which substance, which gives colour to both urine and faeces?
The [blank_start]Bile[blank_end]- ABile
26Heme breakdown pathway:

- CUnconjugated Bilirubin
27Which hormone regulates the differentiation and proliferation of erythroid progenitor cells in the bone marrow to mature red blood cells?
[blank_start]Erythropoietin[blank_end]- AErythropoietin
28Erythropoietin is produced mainly in the [blank_start]kidneys[blank_end]
- Akidneys
