Hint: Oxygen or diatomic oxygen gas is used by the animals for inhalation and it is produced through the photosynthetic process by the plants. A harmful effect of breathing molecular oxygen at increased partial pressure is called oxygen toxicity.
Complete answer:
Oxygen toxicity is a condition which is caused due to breathing of extra supplemental oxygen and it is also known as oxygen poisoning. When oxygen is available and present in higher concentrations especially more than the amount found in the air, enters the lungs and causes damage to the alveoli sacs of the lungs. It leads to the failure of ventilation of the lungs due to the excess supply of oxygen to the tissues.
The breathing of excess amounts of oxygen at increased partial pressure gives rise to hyperoxia which is the condition of increased oxygen in the tissues of the body. The exposure is harmful and it occurs over a long period of time. Prolonged exposure results in the oxidative damage of the cell membranes of the lungs and finally causes damage to the alveoli in the lungs. This condition produces symptoms such as inflammation of the airways, alveoli sacs and tracheobronchitis and results in failure of breathing.
The other parts that are affected by increased levels of oxygen are the retina of the eye, central nervous systems of the body. The important symptoms include dizziness, shortening of breathing, nausea, twitching, anxiety, muscular spasms and in severe condition, seizures may also occur.
Blood poisoning is a condition which arises when chemicals, sometimes produced by bacteria, are released into the bloodstream in order to fight against an infection, triggers autoimmune responses such as inflammation. It is also known as sepsis. The symptoms include fever, increased heart rate, increased breathing and confusion.
Hence, the correct answer is option (C).
Note: Oxygen is an important gas but when increased concentration of the oxygen is breathed results in a condition known as oxygen toxicity. It is caused due to high and prolonged use of supplemental oxygen. This affects the pulmonary airways of the lungs as well as affects the epithelium and results in failure of ventilation of lungs.
