Informative Speech On Aplastic Anemia

Aplastic Anemia is a potentially life threatening syndrome in which the affected person experiences pancytopenia which means there is a reduced production of red blood cells [RBCs], white blood cells [WBCs] as well as platelets. The affected person also will have hypoplastic bone marrow which means that fat replacement in the bone marrow space which is normally filled with hematopoietic precursor cells (Cabrera & Schiebel, 2015). The cells produced by the bone marrow are crucial for supplying oxygen and nourishment to tissues and organs, fighting off infection and clotting of

Anemia is a medical condition defined as having low amounts of red blood cells, thus transporting low levels of oxygen in the blood. Common symptoms include fatigue, weakness, and shortness of breath. Causes for anemia vary, depending on the severity and duration of illness. Regular anemia can result with low levels of iron in the blood. (Mayo Clinic, 2014)

There are several different types of anemia. Some of those are hemorrhagic, iron-deficiency, aplastic, and pernicious. Pernicious anemia is a type of anemia due to a vitamin B-12 deficiency and

Red and white blood cells are the two types of blood cells in the human body. Red blood cells transport oxygen around the body which is transferred through the bloodstream. It moves oxygen into the body and then removes it. They are absorbed through its haemoglobin.

Blood is a bodily fluid that transports oxygen and nutrients to the cells within the body. Blood has plasma that lets the different types of blood travel round the body. Plasma contains proteins that have different functions for the blood- clotting, transporting and defence organisms and osmotic organisations. The plasma carries the red blood cell which has a elastic membrane so it can fit through the small capillaries within the body. Red blood cells can be also known as erythrocytes they don’t have a nucleus when they are matured which gives a bigger space for oxygen, although as there is no nuclei the red blood cells can’t divide so they only live for around 120 days. Red blood cells gain their colour from haemoglobin, oxygenated blood which is known as arterial blood which flows through the arteries coming from the heart and

Iron deficiency anemia, one of the most common types of anemia, is a blood disorder where

Red blood cells are called erythrocytes. Erythrocytes is a cell that travels in the blood. The blood consists of four major parts including red blood cells. Blood is a fluid that is inhuman in order to survive. There are different purposed for the red blood cells that are used to keep the body healthy. Red blood cells have a protein that carries more oxygen molecules from the lungs to the body. Hemoglobin leaves the body and returns carbon dioxide to the lungs. Without out this, people will not survive. When the red blood cell pass through the blood vessels in your body the cell forms a shape of a round shape like a donut. It the center it looks flat. Red blood cells have a lack of the nucleus and survive about 120 days. Red blood cell needs to be replaced by fresh ones daily.

Also known as normocytic anemia. This is the most frequent type of anemia most often happening to males over 85 years old. It is a common problem that occurs to men and women over 85 years old. Symptoms include and are caused by: a reduced production of normal-sized red blood cells even though presence of hemoglobin in the red blood cells is within the standard range; an increased production of HbS as is seen in sickle cell diseases; greater destruction and loss of red blood cells; an increase in plasma volume that is not compensated by anything else; a B2 (riboflavin) deficiency; and a B6 (pyridoxine) deficiency. (Brill & Baumgardner 2000).

These cells can grow into many things such as organs, tissues, muscles, or blood. These cells are able to renew themselves through cell division. One of the most unique aspects to these cells are they are able to replenish and repair themselves as long as the person is alive. This can be seen most commonly in red cells of the bone marrow. These cells are continuously repairing and replacing damaged and old cells. Because of stem cells unique ability to renew themselves into new cells, scientist have shown great interest in these cells. Stem cells that are being studied most by scientist are embryotic stem cells, adult stem cells, and induced pluripotent stem

Anemia is a condition that effects “more than 3 million people in the United States” (Peterson, 2012). Anemia is a decrease in red blood cells (RBCs) or decreased hemoglobin in an individual’s blood. RBCs carry oxygen rich blood throughout an individual’s tissues and organs, allowing the body to function properly. Therefore, an anemic person has a decreased amount of oxygen rich blood flowing through their body. A decreased amount of oxygenated blood is not immediately life threatening but can become very serious. Some potential side effects of anemia are; fatigue, lack of energy, pallor, organ damage, heart failure and death (Peterson, 2012). There are multiple types of anemia with the most common being; iron-deficiency anemia, folic acid-deficiency anemia, vitamin B12 deficiency and microcytic anemia (PDRhealth, 2015).

Hemoglobin is the main substance of the red blood cell. It helps red blood cells carry oxygen from the air in our lungs and releases the oxygen to all parts of the body. From this, normal red blood cells are flexible and round, moving easily through blood vessels.

Anemia is a condition in which the concentration of red blood cells or hemoglobin in the blood is below normal. Hemoglobin is a substance in red blood cells that carries oxygen to the tissues of the body. Anemia results in not enough oxygen reaching these tissues.

Aplastic Anemia (AA) can be idiopathic (~70%), inherited (~15-20%) or acquired due to radiation, tablets, viruses or immune disturbances (~10-15%). Idiopathic and secondary AA is generally immune mediated through autoreactive lymphocytes intermediating damage of hematopoietic stem cells. The clinical course of AA is very different, some patients might have only mild symptoms, needed to be little or no therapy, while others with life-threatening

Aplastic anemia is a rare haemopoetic stem-cell disorder that stems from hypocellular bone marrow, and pancytopenia, which is a medical condition in which there is a reduction in the number of red and white blood cells, as well as platelets (Osnat et.al 2014). If only two parameters from the full blood count are low, the term bicytopenia can be used. The diagnostic approach is the same as for pancytopenia. Previous studies have shown that most patients with acquired aplastic anemia had decreased regulatory T cells (Yang et.al 2013). The regulatory T cells are formerly known as suppressor T cells. They are a subpopulation of T cells which modulate the immune system, maintain tolerance to self-antigens, and abrogate autoimmune disease.

Red blood cells (also referred to as erythrocytes) are the most common type of blood cell and the vertebrateorganism's principal means of delivering oxygen (O2) to the body tissues via the blood flow through thecirculatory system. They take up oxygen in the lungs or gills and release it while squeezing through the body'scapillaries.
