Anemia is defined as a condition characterized by a deficiency in the number of red blood cells or a decrease in the amount of hemoglobin they contain. While both red blood cells and hemoglobin serve essential roles in transporting oxygen throughout the body, the core aspect of anemia is the reduction in red blood cell mass, which can lead to insufficient oxygen delivery to tissues.

In terms of the options provided, while low hemoglobin can indicate anemia, it specifically relates to the functionality of the red blood cells rather than their quantity. Thus, the most precise definition involves a low count of red blood cells.

This distinction is crucial in veterinary medicine, as it helps practitioners diagnose and treat conditions that can lead to anemia in various species. Understanding the underlying causes of anemia, which are related to the loss, destruction, or inadequate production of red blood cells, allows for more effective treatment and management of the condition.
