Oxygen binding capacity and oxygen content
Hemoglobin's oxygen binding capacity refers to the maximum amount of oxygen that can be bound to hemoglobin (Hb) which is the main protein found inside red blood cells. The oxygen binding capacity of hemoglobin is affected by various factors, including pH, temperature, and the presence of other chemicals such as carbon dioxide and bicarbonate.
Blood's oxygen content is the amount of oxygen in a certain volume of blood, typically 100mL. It is influenced by several factors, including the concentration of hemoglobin, the partial pressure of oxygen, and the amount of oxygen that is bound to hemoglobin.
