Final answer:
Suffocation, asphyxiation, and poisoning are health hazards that can disrupt the normal flow of air and oxygen in the body, leading to severe consequences.
Step-by-step explanation:
Suffocation, asphyxiation, and poisoning are health hazards. Suffocation occurs when the flow of air into the lungs is mechanically obstructed, preventing breathing and potentially resulting in asphyxia or suffocation. Asphyxiation refers to the complete obstruction of airflow, leading to a lack of oxygen and suffocation. Poisoning can occur through exposure to toxic substances like carbon monoxide or cyanide, which interfere with bodily functions such as oxygen delivery and cellular respiration.
