Hemoglobin Hb or Hgb is an iron-rich protein that carries oxygen and makes the blood red. The hematocrit reflects the amount of space in the blood that is occupied by RBCs. Not all the RBCs are the same size; some are larger and some are smaller. In patients with anemia, hemoglobin levels are low and the patient may be frequently tired and have little energy. This is because there is not enough hemoglobin to carry oxygen to the stationary tissues; thus, there is not enough oxygen available to convert nutrients into energy.
Low RBC counts, hemoglobin and hematocrit levels can be caused by other things too, such as a lot of bleeding or malnutrition not enough nutrients in the food eaten. Kidney disease, liver disease cirrhosis , cancer, and medications used to treat cancer can also cause low levels. An increased RBC count and increased levels of hemoglobin and hematocrit may be caused by dehydration not enough water in the body or by some diseases see table.
WBCs help the body fight illness or infection. As part of the immune system, they recognize and fight things that are foreign to not part of the body. There are 5 types of WBCs; each type plays a different role in protecting the body from invaders. The WBC count may increase when you have an infection caused by bacteria, viruses, fungi, or parasites. The WBC count can also increase in patients with leukemia, a cancer of the blood. Thus, doctors use the WBC count to help determine if a patient has an infection or leukemia.
When the WBC count is increased, the type of WBC can help differentiate between a bacterial infection, viral infection or leukemia. Doctors also use the WBC count to monitor various types of illness, since it may decrease in response to therapy during recovery from an illness. When performing a differential, a medical technologist looks at the various cells under a microscope.
A differential provides information about the relative numbers that is, the percentage of each type of WBC. Such information helps the doctor determine whether an illness is caused by a bacteria, a virus, or leukemia. A differential can be used to monitor patients with allergies and to determine how a patient is recovering from an illness or responding to therapy. Thanks S lot stay blessed always ameen. I commented it first time. Rbc ko survive karne ke liye oxygen chahiye?

Summary: Red blood cells are a very essential part of our blood, and as a matter of fact it is the most plentiful type of blood cells in our body. RBCs are the normal cells in the blood, hemoglobin is a protein that is in the RBC which binds with dissolved oxygen to give oxyhemoglobin and then releases it close to a tissue which is low in oxygen and takes the CO2 from the tissue in another form of CO2 don't want to complicate it and becomes deoxyhemoglobin.
What's the difference between red blood cells and hemoglobin? Ahmad H. Mar 4, Iron-deficiency anemia. If you don't have enough iron in your body, your body won't be able to make enough red blood cells.
Iron-deficiency anemia is the most common form of anemia. Causes of iron deficiency include:. Sickle cell anemia. In this inherited disease, the red blood cells are shaped like half moons rather than the normal indented circles. This change in shape can make the cells "sticky" and unable to flow smoothly through blood vessels.
This causes a blockage in blood flow. This may cause sudden acute or chronic pain. It can also lead to infection or organ damage. Sickle cells die much more quickly than normal blood cells—in about 10 to 20 days instead of days.
This causes a shortage of red blood cells. Normocytic anemia.
