Conclusion – Transport of Oxygen in Blood

How is Oxygen Transported in Human Beings?

The oxygen binds to the hemoglobin to form oxyhemoglobin. It is a reversible reaction in which haemoglobin present on RBCs (or red blood cells) and containing four atoms of iron binds with oxygen in a reversible reaction....

Haemoglobin Protein in Blood

Haemoglobin is a protein found in red blood cells that is essential for transporting oxygen from the lungs to the rest of the body and returning carbon dioxide from the tissues back to the lungs. It consists of four subunits, each containing an iron atom that can bind to one oxygen molecule. Haemoglobin also plays a role in maintaining the acid-base balance of the blood....

Relationship Between Haemoglobin and Partial Pressure of Oxygen

The partial pressure of oxygen or pO2 is the most important factor that determines the binding of oxygen with hemoglobin i.e. high pO2 higher the binding and low pO2 lowers the binding. When all the hemoglobins present completely binds with oxygen, the hemoglobin is said to be fully saturated whereas if there is free hemoglobin remaining then the hemoglobin is said to be partially saturated....

Factors Affecting Affinity of Haemoglobin for Oxygen

There are certain factors other than partial pressure that affects the Hb-O2 affinity. These factors determine whether the oxygen-hemoglobin dissociation curve will shift towards the right i.e. lower affinity of O2-Hb or the curve will shift towards the left i.e. higher affinity of O2-Hb. These factors are;...

Conclusion – Transport of Oxygen in Blood

The transport of oxygen in the blood is a complex yet efficient process primarily facilitated by hemoglobin. Oxygen binds to hemoglobin in the lungs, forming oxyhemoglobin, and is released to tissues based on various physiological factors. The oxygen-hemoglobin dissociation curve illustrates how oxygen affinity changes with partial pressure, pH, carbon dioxide levels, and temperature. Understanding these mechanisms is crucial for appreciating how the body maintains oxygen supply under different conditions, ensuring proper cellular function and overall metabolic activity....
