Lack of heamoglobin, lack of iron etc
Anemia is the medical term meaning the blood has a reduced ability to carry oxygen due to inadequate hemoglobin or red blood cells. Anemia has many different causes, but iron deficiency is a common one.
Without RBC the ability of the blood to transport oxygen would be reduced significantly
Hypoxia, .e., reduced oxygen tension in blood.
Hemoglobin gives the red blood cells the ability to carry oxygen.
It is dangerous for the mother because of blood loss, loss of clotting ability, and oxygen deprivation to her organs (especially the kidneys and heart). This condition is dangerous for the fetus because of oxygen deprivation
The condition of deficient oxygen is hypoxia, and the condition of no oxygen is anoxia. Blood cells are aerobic so they need oxygen to survive. If you have below normal oxygen levels, you're not providing your blood with its fuel; you're basically starving your blood cells. Blood delivers oxygen to your tissues before returning to your lungs to fill up again. So if your blood isn't getting enough oxygen, neither will any other part of your body.
When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased
cyanosis
Sickle cell anemia produces sickle-shaped RBCs that reduce the ability to carry as well as exchange oxygen with tissues.
