Question

what is acclimatization? if you moved from Madison at sea level to Santa Fe at 7000 feet above sea level, how would your kidneys react to the altitude change?

Premature babies may have IRDS how does this condition affect the infant respiratory system?

Answer 1

Acclimatisation is the process through which an organism change its, behaviour, morphological traits or biochemical compostition to adjust to a new environment like change in temperature or altitude.
When someone shifts to high altitude the oxygen dissolved in blood lowers causing hypoxia due to presence of less amount of oxygen in air at high altitudes. This triggers the chemoreceptors which sends sensory signals to hypothalamus. The hypothalamus sends signals to the kidney to release erythropoietin which acts on the bone marrow. Erythropoietin causes bone marrow to produce more RBC which raises the number of RBC in blood. Increased RBC results in carrying more oxygen to the body tissues which compensates for low oxygen in blood.
Infant respiratory distress syndrome or IRDS is respiratory condition affecting the lungs of premature infants. The lungs of premature infants lacks surfactant which causes collapse of thd lung spaces or alveoli. This results in impaired gas exchange causing high levels of carbon dioxide in body and low oxygen leading to hypox
