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.
Oxygen-Carrying Capacity of Hemoglobin
Hemoglobin is vital for oxygen transport in the blood, with each molecule capable of binding up to four oxygen molecules. This binding capacity ensures efficient oxygen delivery from the lungs to various tissues. Several factors, including blood pH, temperature, and carbon dioxide levels, can affect hemoglobin’s ability to release oxygen. This efficient oxygen transport system is essential for sustaining cellular respiration and overall metabolic activities in the body.
Oxygen Transport in Blood
Oxygen is transported in the blood by binding to hemoglobin. Blood is responsible for the transportation of gases between the lungs and body tissues. Oxygen is transported bound to hemoglobin as it does not dissolve well in water present in plasma i.e. 97% of oxygen is transported with hemoglobin and the remaining 3% in plasma.
In this article, we will cover how oxygen is transported in blood, in detail.
