1. pH levels: The affinity of hemoglobin for oxygen is influenced by the pH level of the blood. A decrease in pH (acidosis) causes hemoglobin to release oxygen more readily, while an increase in pH (alkalosis) causes hemoglobin to hold onto oxygen more tightly. This is known as the Bohr effect.
2. Temperature: Higher temperatures can cause hemoglobin to release oxygen more readily, while lower temperatures can cause hemoglobin to hold onto oxygen more tightly. This is because higher temperatures increase the metabolic rate of tissues, leading to increased oxygen demand.
3. Partial pressure of oxygen: The partial pressure of oxygen in the blood also affects the release of oxygen from hemoglobin. When the partial pressure of oxygen is high (e.g. in the lungs), hemoglobin binds oxygen more readily. When the partial pressure of oxygen is low (e.g. in tissues), hemoglobin releases oxygen more readily to meet the oxygen demands of the cells.

1. Partial Pressure of Oxygen (pO2): When the pO2 in the tissues is low, oxyhemoglobin releases oxygen more readily to satisfy the metabolic demands of the cells. This is because the equilibrium of the oxyhemoglobin dissociation curve shifts to the right, promoting the dissociation of oxygen from hemoglobin.
2. pH: A decrease in pH (acidic conditions) favors the release of oxygen from hemoglobin. This is due to the Bohr effect, which states that acidic conditions reduce hemoglobin's affinity for oxygen. The protons released under acidic conditions compete with oxygen for binding sites on hemoglobin, causing oxygen to dissociate more easily.
3. Temperature: An increase in temperature also promotes oxygen release by oxyhemoglobin. Higher temperatures cause the oxyhemoglobin dissociation curve to shift to the right, resulting in a reduced affinity of hemoglobin for oxygen. This facilitates the release of oxygen into the tissues, which have a higher metabolic demand at elevated temperatures.
