Red blood cells, which are smaller then the normal ones are called microcytes. They are generally less than 6um, while normal, mature red blood cells measure 7-8 um in diameter. The reason for the smaller size is inefficient or defective haemoglobin production.
Iron deficiency anaemia happens if the body hasn't got enough iron for the haemoglobin synthesis (production). Haemoglobin, a large protein, contains heme groups with iron atoms. It is where the oxygen is carried (and the carbon dioxide as well). The body has iron storages, and normally loses very little iron. But, if more iron is needed (bleeding, rapid adolescence growth, pregnancy, lactation, for example), and the intake of dietary iron is not enough, the storages got depleted.
The produced red blood cells (as they have less haemoglobins in them) will be smaller and also paler (hypochromic), as haemoglobin is the pigment which gives the red colour to the red blood cells.
Thalassaemia is another disease which characteristically has small (microcytic) and pale (hypochromic) red blood cells. Thalassaemia is an inherited condition in which the haemoglobin are defective. The defective red blood cells got destroyed much sooner than normal red blood cells are.
In both conditions, the decreased haemoglobin leads to anaemia, the insufficient oxygenation of body tissues.
Anemia is a condition characterized by the inability of red blood cells to carry the required amount of oxygen to tissues
Hemoglobin Haemoglobin.
Anemia
people with this disease normally will have to carry an oxygen tank with them where ever they go.
Sickle Cell Anemia
blood cells do not carry food, blood cells carry oxygen.
Red blood cells carry oxygen to all the cells of the body.
The Red blood cells carry oxygen to the muscles, and I believe the blood itself carries waste and substances to cells. White Blood cells fight disease.
Anemia is a disease where the blood doesn't carry enough oxygen, due to either a lack of blood cells or hemoglobin, or damage to the blood cells or hemoglobin.
people with this disease normally will have to carry an oxygen tank with them where ever they go.
The blood cells can't carry as much oxygen as they should be able to carry. So the body gets less oxygen.
The blood cells can't carry as much oxygen as they should be able to carry. So the body gets less oxygen.
In case of human being you have red blood cells in your blood. They contain haemoglobin. This can carry seventy times more oxygen than plasma can carry. ( Say about 280 ml/ 100 ml of blood.) The bonding of oxygen is strong enough to hold the oxygen at lungs and to carry it in blood. Here the oxygen concentration is high. This bonding is loose enough to give oxygen at proximal end of the capillaries. Here oxygen concentration is low. This oxygen is carried through the interstitial fluid to the cells.
white blood cells protect the body from disease while red carry oxygen
Sickle Cell Anemia
Systemic Arteries carry oxygen rich blood (also called oxygenated blood). Pulmonary Arteries carry oxygen poor (deoxygenated) blood
White blood cells that fight disease, red blood cells which carry oxygen, and platelets that form scabs.
By definition, ALL arteries carry Oxygen rich blood. Veins carry oxygen depleted blood.
Veins carry oxygen depleted blood to the heart.
B/c the iron in the blood is what carries the oxygen around the body. With too little iron, not enough oxygen carriers.
