Study Notes
Blood Cell Production in Embryonic Development
- At age 20 weeks of embryonic life, bone begins to produce red blood cells (R.B.C.s).
- In early embryonic life, R.B.C.s are produced by the yolk sac, spleen, and later by the liver.
Erythrocyte Count Terminology
- An increase in the count of R.B.C.s above the normal value is referred to as erythrocytosis.
Specific Bones Involved in R.B.C. Production
- Flat bones play a critical role in producing R.B.C.s during later stages of development.
- Examples of flat bones that produce R.B.C.s include the bones of the skull, ribs, and sternum.
