A 38-year-old member asked:

Why can red blood cells carry oxygen while other cells can't?

Hemoglobin: Red cells are bags of hemoglobin. It is hemoglobin that carries oxygen. Other cells do not have hemoglobin. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex.

Hemoglobin: Hemoglobin is the actual molecule that carries oxygen. Red cells are bags full of hemoglobin. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually.

A 40-year-old member asked:

If red blood cells carry oxygen, do they also carry carbon dioxide?

To some degree: • While O2 is transported via the Hgb of the RBC, carbon dioxide is more soluble in blood than oxygen. About 5 % of carbon dioxide is transported unchanged, simply dissolved in the plasma. Carbon dioxide additionally does combines reversibly with haemoglobin to form carbamino haemoglobin. About 10 % of carbon dioxide is transported bound to haemoglobin and plasma proteins.
