How is oxygen and carbon dioxide transported in human beings?
Answer:
Oxygen and carbon dioxide are transported in human beings through the respiratory and circulatory systems.
Oxygen Transport:
When you breathe in, oxygen enters your lungs and moves into the bloodstream through tiny blood vessels called capillaries. Hemoglobin, a protein in red blood cells, binds to the oxygen molecules in the lungs and carries them to the body’s tissues and organs. This process is called oxygenation.
Carbon Dioxide Transport:
As the cells in the body use oxygen, they produce carbon dioxide as a waste product. This carbon dioxide is transported back to the lungs through the bloodstream. It is carried in the form of bicarbonate ions, dissolved in the plasma, and bound to hemoglobin. When the blood reaches the lungs, carbon dioxide is released from the blood and exhaled out of the body during the process of respiration.
In summary, oxygen is transported from the lungs to the body’s tissues by binding to hemoglobin in red blood cells, while carbon dioxide is transported from the body’s tissues back to the lungs to be exhaled out of the body.
