Which statement about hypoxia and anoxia is true?

• A. Anoxia is death due to complete lack of oxygen
• B. Hypoxia is loss of oxygen and Anoxia is death due to complete lack of oxygen
• C. Hypoxia and Anoxia are the same
• D. Hypoxia is a partial oxygen deficiency

Answer: (A)

Understanding the difference between hypoxia and anoxia is key here: hypoxia means not enough oxygen is reaching the tissues, while anoxia means a complete absence of oxygen. The statement that anoxia is death due to a complete lack of oxygen aligns with the severe, life-threatening nature of no oxygen reaching the body's cells. When there is no oxygen at all, brain and heart tissue can stop functioning within minutes, leading to death if oxygen isn’t restored. The other options either misdefine hypoxia as simply a loss of oxygen, claim the two terms are the same, or restate a partial deficiency without addressing the complete absence, making them less accurate.
