Which of these is a disorder related to the respiratory system?

Upper Respiratory Infections (URI) are directly related to the respiratory system, as they affect the nasal passages, throat, and lungs. URIs are characterized by symptoms such as coughing, sneezing, congestion, and sore throat, which are all manifestations of inflammation or infection in the upper respiratory tract. This makes them a clear example of disorders that impact respiratory function and health.

In contrast, Congestive Heart Failure primarily involves the circulatory system, where the heart's ability to pump blood is compromised, leading to fluid buildup and respiratory issues as secondary effects. Diabetes Mellitus is a metabolic disorder that pertains to insulin and blood glucose regulation rather than respiratory health. Skin cancer, meanwhile, involves abnormal growth of skin cells and does not relate to respiratory functions. This distinction highlights why Upper Respiratory Infections are the only choice directly associated with the respiratory system among the options provided.
