discuss the factors affecting the transport of oxygen in the blood
Oxygen gets bind to hemoglobin in blood and gets transported throughout the body. Each hemoglobin binds to four oxygen molecules.
When oxygen combines with hemoglobin in the blood it forms oxy-hemoglobin and it helps in transport of oxygen to different parts of the body where the oxygen then dissociates from the oxy-hemoglobin and enters the cells.
This depends upon temperature, pH and Bi-phosphoglyceric acid (BPG).
When the temperature increases then more readily oxygen dissociates from hemoglobin due to which oxygen gets released from oxy-hemoglobin and enters the cells of the tissues.
When the pH decreases then more readily oxygen dissociates from hemoglobin due to which oxygen gets released from oxy-hemoglobin and thus enters the body cells.
When the concentration of BPG increases then more readily oxygen dissociates from hemoglobin due to which oxygen gets released from oxy-hemoglobin and oxygen enters the cells.
