What is the oxygen poor blood?

What is the oxygen poor blood?

Few basic reasons: Haemoglobin- a protein molecule, carries o2 in the blood vs called arteries and after o2 is used by tissues, the deoxyg. Hb is carried by vessels called veins -> heart -> lungs to get new o2 molec. Added. When hb is low in quantity or abnl.In str-> o2 is low in blood. Iron, folate, (folic acid) B12 deficiency- anemia o2 defective basic str.As in thalssemia, sicklecell dz. 2.Heart defects->mixing a &venous bloo. ...Read more
