The texts provided discuss the role of surfactant in maintaining lung function and the consequences of its deficiency. It explains that surfactant is secreted by alveolar type II cells and helps reduce surface tension in the alveoli. The production of surfactant begins during the third trimester of pregnancy. The lack of surfactant can result in respiratory distress, leading to reduced pulmonary compliance and increased surface tension. This can cause alveoli collapse and a decrease in gaseous exchange. The condition is known as respiratory distress syndrome (RDS) or hyaline membrane disease and can occur in both premature and full-term infants. It can lead to respiratory acidosis, characterized by increased carbon dioxide levels and decreased blood pH. The infant's body compensates for this acid-base disorder by increasing the reabsorption of bicarbonate ions from urine back into the bloodstream. Overall, the texts provide a clear explanation of the topic and address the relevant points. The information is presented in a coherent manner, and the formatting is appropriate. However, it would be helpful to include more specific details about the consequences of surfactant deficiency and the compensatory mechanism of the infant's body. Additionally, it would be beneficial to include any mathematical equations or calculations related to the topic. Question: Could you provide more information about the specific consequences of surfactant deficiency and how the compensatory mechanism of the infant's body works in detail?
