A. True
B. False

Answer 1

Hint: Smoke inhalation is when you breathe in harmful smoke from burning materials and gases. Various toxic chemicals like cyanide, carbon monoxide are present in the smoke.

Complete Answer:
When a person inhales harmful smoke, lungs and airways may become irritated, swollen, and blocked. Due to the damage caused to the lungs, it prevents the oxygen from getting into the human’s blood and sudden respiratory failure can occur.
The meaning of respiratory failure is that a person is not able to breathe properly because oxygen level is low. If the respiratory system malfunction then the body will not get enough oxygen which may further lead to cardiac arrest or heart attack and other heart & health problems. There are many disorders because of smoke like infection, hypersensitivity and allergic disorders.
Although asthma is the most common form of respiratory allergic disorders, pneumonias are not uncommon, but more persistent and serious. Indoor air ventilation systems, coolers and air-conditioners, dampness, decay, pet animals, production or handling of the causative items are responsible for these hypersensitivity diseases. So, smoke has very harmful effects that affect our lungs and heart both.

Thus, the correct answer is TRUE.

Note: Smoke is a very major constituent of air pollution. The effect of polluted air on all living organisms is quite dangerous and, in some cases, can lead to loss of life. So, we should be very careful with our actions and try to minimize the pollution & keep our planet healthy & safe.
