MICROANATOMY

Detailed explanation-1: -The respiratory system may be particularly affected by cold air exposure as inspired air has to be conditioned before participating in peripheral lung gas exchange, with an associated loss of heat and water.

Detailed explanation-2: -Acute or chronic cold exposure elicits several effects on the respiratory system. Pulmonary mechanics are compromised by bronchoconstriction, airway congestion, secretions and decreased mucociliary clearance.

Detailed explanation-3: -Prolonged exposure to cold will eventually use up your body’s stored energy. The result is hypothermia, or abnormally low body temperature. A body temperature that is too low affects the brain, making the victim unable to think clearly or move well.

Detailed explanation-4: -Exposure to cold has often been associated with increased incidence and severity of respiratory tract infections.

Detailed explanation-5: -Some chest colds advance to pneumonia, which is an infection of one or both lungs. Pneumonia develops when an infection in your airway travels to your lungs. Distinguishing pneumonia from bronchitis can be difficult.
