Particles in smoke can irritate which of the following?

Particles in smoke can irritate the eyes and respiratory system, making these areas particularly vulnerable to the effects of smoke exposure. Smoke contains a variety of irritants, including particulate matter and chemical compounds that can lead to eye discomfort, such as redness, tearing, or a burning sensation. Similarly, when inhaled, particles can irritate the respiratory system, causing symptoms like coughing, difficulty breathing, or throat irritation.

While the skin can also be affected by smoke in some cases, especially through contact with heated or burning materials, the primary and most significant irritants are those affecting the eyes and respiratory tract. The irritation of the digestive system, however, is less commonly associated with smoke exposure, as it usually occurs in situations involving ingestion or inhalation of specific harmful substances rather than smoke itself. Thus, the correct response focuses on the more immediate and well-documented effects in the eyes and respiratory system.
