Verified step by step guidance

Understand the term 'erythropoiesis': Erythropoiesis is the process by which new red blood cells (erythrocytes) are produced in the bone marrow.

Identify the primary trigger for erythropoiesis: The main stimulus for erythropoiesis is low oxygen levels in the blood, a condition known as hypoxia.

Recognize the role of erythropoietin: When oxygen levels are low, the kidneys release a hormone called erythropoietin, which signals the bone marrow to increase the production of red blood cells.

Consider the physiological response: Increasing the number of red blood cells enhances the blood's capacity to carry oxygen, thereby addressing the hypoxic condition.

Evaluate the options: Elevated blood pressure, increased blood glucose levels, and high levels of carbon dioxide do not directly trigger erythropoiesis. Low oxygen levels are the correct trigger.
