During acclimatization to high altitude all of the following take place except
**Core Concept**
High altitude acclimatization is a complex physiological process that involves various adaptations to counteract the effects of hypoxia, which occurs due to the lower oxygen levels at high altitudes. The body attempts to compensate for the reduced oxygen availability by increasing red blood cell production, increasing capillarization, and increasing ventilation.
**Why the Correct Answer is Right**
During acclimatization to high altitude, several physiological changes occur to help the body adapt to the lower oxygen levels. These changes include an increase in red blood cell production, which is mediated by erythropoietin, a hormone produced by the kidneys. This increase in red blood cell count helps to increase oxygen delivery to tissues. Additionally, capillarization increases, allowing for more efficient oxygen delivery to tissues. Ventilation also increases, allowing for more oxygen to be taken in. However, one adaptation that does not occur during acclimatization to high altitude is an increase in the myoglobin content of muscles.

**Clinical Pearl / High-Yield Fact**
It's essential to note that acclimatization to high altitude is a gradual process that occurs over several days to weeks. Failure to acclimatize properly can lead to high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE), which are life-threatening conditions.
**Correct Answer:** A.
