Question

How the body makes long-term adjustments when living in high altitude.

Short Note

Solution

  • When a person travels from sea level to elevations where the atmospheric pressure and partial pressure of O2 lowered there is a poor binding of O2 with haemoglobin leads to acute mountain sickness.
  • When the person lives there for a long time the kidney synthesizes the erythropoietin which stimulates the bone marrow to produce more RBCs.
