What's Covered

This lesson will identify various types of blood disorders and their characteristics. We will look at:

  1. Anemia
  2. Leukemia
  3. Toxemia
  4. Septicemia

1.Anemia

Anemia is a type of blood disorder in which red blood cells do not deliver enough oxygen to the body. One of the main problems of anemia is that it results in fatigue because the tissues and organs of the body are not getting the oxygen that they need and there are various forms of anemias.

Term to Know

    • Anemia
    • A group of disorders that afflict red blood cells, anemia affects a red blood cell’s ability to transport gasses.

One specific type of anemia is sickle cell anemia, which is a type of inherited anemia. With this type of disorder, red blood cells are sickle-shaped or crescent-shaped and are also stiff and tend to be sticky. The result is that oftentimes they will block blood flow in vessels causing fatigue and pain.

Term to Know

    • Sickle Cell Anemia
    • Classified as hemolytic anemia, sickle cell anemia is caused by a genetic mutation that causes an abnormality in hemoglobin structure. The abnormal hemoglobin crystallizes and changes the shape of red blood cells from a short biconcave disk into a long sickle shaped cell.

Malaria is another type of blood disorder associated with anemia. With his type of disorder, protozoans will be transmitted by mosquitoes and will then multiply inside of the red blood cells. Eventually this will cause red blood cells to burst. Because the red blood cells that burst die, there are not enough red blood cells bringing oxygen throughout your body.

Symptoms of this type of disorder include

  • Fever
  • Chills
  • Death

This disorder is more common in places that are very warm and moist, that have a lot of mosquitoes.

Term to Know

  • Malaria
  • A mosquito-borne disease that first infects the liver, from there the infection spreads to red blood cells. Malaria is caused by a parasite that is transmitted via mosquitoes.

2.Leukemia

Leukemia is a type of cancer caused by a DNA mutation, and, in this disorder, causing an overactive growth of white blood cells that will destroy bone marrow. There are several different forms of leukemia, but all of them start in the bone marrow and then can spread throughout the body.

Term to Know

    • Leukemia
    • A cancer of red bone marrow that causes a significant increase in circulating white blood cells (leukocytes).

3. Toxemia

Toxemia is the spreading of toxins in the bloodstream, and is also sometimes known as blood poisoning. In this disorder is that metabolic wastes are not properly removed. Different organs and structures in your body usually take care of metabolic waste and dispose of it properly, but, when this does not happen, that metabolic waste will build up in your blood.

This can lead to:

  • Anemia
  • Improper clotting
  • Possibly death.

Term to Know

    • Toxemia
    • A general term to describe blood poisoning.

4.Septcemia

Septicemia is when bacteria within the body will release toxins into the blood, and these toxins can damage or destroy red blood cells.

Example Staph A -a type of bacterial infection. MRSA is a type of staph A that is antibiotic-resistant.

Term to Know

    • Septicemia
    • When organisms, such as bacteria, get into the circulating blood and cause a system-wide infection.

Summary

There are several different blood disorders that can occur. Anemia is the term for a group of disorders that affect red blood cells and their ability to bring oxygen to the body. One such type is sickle-cell anemia, an inherited disease. Malaria is also associated with anemia. Leukemia is a cancer that causes an overproduction of white blood cells. Eventually this will lead to the destruction of bone marrow. Toxemia is the spreading of toxins in the bloodstream, and is also referred to as blood poisoning. Septicemia is when bacteria release toxins into the blood which damage or destroy red blood cells.
