Study Notes
Red Blood Cell (R.B.C.) Production
- R.B.C.s are initially produced by the yolk sac during early embryonic life.
- As development progresses, the spleen and liver take over as the primary sites for R.B.C. production.
- Around the age of 20 weeks of gestation, bone marrow begins to produce R.B.C.s, transitioning to the primary source for R.B.C. generation postnatally.
- Flat bones, such as those in the skull, ribs, and sternum, are significant contributors to R.B.C. production in adults.
Increase in R.B.C. Count
- An increase in R.B.C. count beyond the normal range is referred to as polycythemia.
- Polycythemia can occur due to various physiological or pathological conditions, leading to increased blood viscosity and potential complications.
