It directly damages the heart muscle, leading to cardiovascular problems.
It stimulates the immune system, causing inflammation and tissue damage.
It prevents the body from producing energy by interfering with oxygen uptake. (correct)
It causes the body to release excess carbon dioxide, leading to respiratory distress.

It binds to hemoglobin, preventing oxygen from attaching and being transported to tissues. (correct)
It directly damages red blood cells, reducing their ability to carry oxygen.
It interferes with the production of red blood cells, leading to anemia.
It increases the affinity of hemoglobin for oxygen, making it difficult for oxygen to be released to tissues.

Carbon monoxide disrupts the flow of blood to the tissues, depriving them of nutrients and oxygen.
Carbon monoxide damages the mitochondria, the powerhouses of cells, rendering them dysfunctional.
The lack of oxygen delivered to tissues prevents the breakdown of glucose for energy production. (correct)
Carbon monoxide directly inhibits the enzymes involved in cellular respiration.

The body's survival depends on two essential processes involving oxygen: oxidization of food in tissues by arterial oxygen-rich blood for metabolic activity, and producing energy for body organs to function.

Bronchioles branch out from bronchi through 15 divisions, resulting in thinner walls with less cartilage.

Proper oxygenation of blood depends on both oxygen supply and circulation; failure in either process hinders oxygenation.

During expiration, diaphragm and intercostal muscles relax, returning the thoracic cavity to its original volume, increasing air pressure in lungs, and forcing air out.
