Explanation:
The process in which Haemoglobin works depends by the environmental conditions of blood, especially with the partial pressures of O₂ and CO₂ related with the concentration of these compounds. When blood enters in the lungs, the haemoglobin get oxygenated because there is a high concentration of O₂ (meaning that the partial pressure of oxygen is high), liberating CO₂ that will be exhaled. The haemoglobin saturated with oxygen is known as oxyhaemoglobin
When blood flows in the body, found in the tissues higher concentrations of CO₂ which is more efficiently united with the haemoglobin, liberating the oxygen in the tissues for cell respiration, the haemoglobin them has form a reaction with the CO₂ which will travel back to the lungs and the cycle will begin again.
The three ways in which CO₂ travel are: Diluted in the plasma, as bicarbonate and combined with proteins (Haemoglobin) as a carbamine compound.
The CO₂ diluted in plasma, is due to the great capacity of dilution of the CO₂ which could be almost 20 times higher than O₂ capacity of dilution.
Bicarbonate is formed in the red blood cell when CO₂ and the enzyme name carbonic anhydrase reacts with water, forming a carbonic acid, when the concentration of these ions is elevated the carbonic acid becomes bicarbonate liberating a H₊ wich is united in the haemoglobin.
Carbamine compound form in the proteins families of the globines, being the most important the reaction in the haemoglobin.
A condition in which a person develops intense cravings for the substance and the inability to control their behaviors in regards to obtaining and using it is called<u> "addiction".</u>
Addiction refers to the physical and mental state or excessive dependence on something in which a person loses self-control over his undesirable actions.
Once this becomes a habit then it becomes difficult to get out of it.
As a result of overindulgence and great involvement in alcohol and drugs, it can lead to serious health issues such as heart risk, lung infection, and memory loss.
A person suffering from such a condition must be admitted to a drug treatment center.
