Which term describes a decreased level of hemoglobin, red blood cells, or packed cell volume?

• A. Anorexia
• B. Anemia
• C. Anterior
• D. Apnea

Answer: (B)

Anemia is the term used for a decreased level of hemoglobin, red blood cells, or packed cell volume, which lowers the blood’s capacity to carry oxygen. Hemoglobin is the oxygen-carrying protein inside red blood cells, red blood cell count measures how many cells are present, and packed cell volume (PCV) reflects the proportion of blood that is made up of cells. When any of these fall, tissues receive less oxygen, leading to signs like weakness or pale mucous membranes. The other options don’t describe this blood‑level change: loss of appetite is anorexia, a directional term describes a location (anterior), and apnea means not breathing.
