You are on an emergency medicine (EM) rotation rotation and you have an elderly patient that has come to you because they raised the temperature in their hot tub as high as it will go and, after a few minutes in the very warm water, felt faint, past out, and nearly drowned (note that while the elderly tend to migrate to warmer climates, they are constantly at risk of overheating; however, this hot tub fainting effect can happen in younger people as well). What happened here with respect to vasodilation, venous return and cardiac output which led to them having to visit the emergency room (ER)/emergency department (ED)?

Cystic fibrоsis (CF) is а genetic diseаse we will cоme bаck tо periodically. The pathophysiology involves a mutation in the CFTR (cystic fibrosis transmembrane conductance regulator) gene which encodes for a vital chloride channel protein. This leads to mucus blocking primarily the airways and pancreatic ducts (but also other digestive system organs as well as some sweat gland ducts and reproductive system ducts). The reason a dysfunctional chloride channel leads to airway blocking is because without proper chloride transport into the airway lumen___________________.
