A single drop of blood contains millions of erythrocytes and just thousands of leukocytes. Specifically, males have about 5.4 million erythrocytes per microliter (µL) of blood, and females have approximately 4.8 million per µL. In fact, erythrocytes are estimated to make up about 25 percent of the total cells in the body.

It highlights the importance of appropriate Hb cutoff values for anemia diagnosis, particularly emphasizing the need for age-specific adjustments for vulnerable populations. Additionally, it covers measurement techniques for Hb, advocating for standardized methods to ensure accurate diagnoses across diverse settings.

Derived from hemoglobin and hematocrit measurements, these indices vary based on anemia type and require fresh blood samples for accuracy. While automated machines have improved readings, further tests like serum iron and ferritin are necessary due to their lack of specificity.

It explains how the respiratory system provides oxygen to the body, removes carbon dioxide, and maintains acid-base balance. Key structures involved include the conducting zone (nose, pharynx, trachea) and respiratory zone (alveoli).

They lack organelles and rely on anaerobic respiration, with hemoglobin playing a key role in oxygen delivery. Erythropoiesis is regulated by erythropoietin (EPO) in response to oxygen levels, and essential minerals like iron, copper, and zinc, along with B vitamins, support hemoglobin production.
