White blood cell

Leukopenia Leukopenia is a condition in which you have a low number of white blood cells. White blood cells help the body fight infections. The number of white blood cells in the body varies from person to person. Leukopenia is usually defined as having fewer than 4,000 white blood cells in 1 microliter of blood. There are five types of white blood cells. Two types (lymphocytes and neutrophils) make up most of the white blood cell count. When lymphocytes are low, the condition is called…

production of white blood cells, red blood cells, or platelets is interrupted (Myelodysplastic Syndrome Treatment 2016). These syndromes are rare, fewer than 14,000 cases of myelodysplastic syndromes occur in the United States each year (Statistics about Myelodysplastic syndromes). Blood cells and bone marrow do not fully develop or become mature enough to function properly when a person has myelodysplastic syndromes. Blood cells not becoming mature can cause many problems. If the white blood…

group of blood diseases that affects new blood cells. This syndrome starts in the bone marrow where new blood cells are made. New blood cells are called immature cells or stem cells. With MDS, some immature cells do not grow into adult blood cells. Immature blood cells cannot live for very long in the body and they die. Over time, immature blood cells crowd out normal adult blood cells. This causes a low blood count. The bone marrow produces red blood cells which carry oxygen, white blood cells…

Blood is composed of two elements which are plasma and formed elements. Blood plasma is the main component of blood occupying on average about 55% of the total blood volume. The main component of plasma is water making up to 92% of the volume of the plasma. Other components of the plasma are substances like proteins, carbohydrates, amino acids, lipids, vitamins, electrolytes, hormones cellular waste products and dissolved gasses. The formed elements part of the blood are composed of the cellular…

system consists of the heart, blood vessels, and blood (“Major Functions,” n.d.). Leukemia is a malignant cancer of the blood and bone marrow that affects this system and involves an abnormal growth of white blood cells (McGlaufin, Munger, and Nelson, 2015). Acute Myeloid Leukemia (AML) is a subtype of this disease and is most common in older adults, specifically males 65 and older (Turbeville, 2014). In AML, the bone marrow produces abnormal white blood cells, red blood cells, or platelets…

causes this disease? Aplastic anemia is a life threatening condition that causes a deficiency of all types of blood cells in the body by a failure of the bone marrow development. The symptoms of this disorder is very similar to a type of cancer known as leukemia. The condition is diagnosed by several tests that include blood tests which shows the levels of the white blood cells, red blood cells and the platelet count, and finally a bone marrow biopsy is done to confirm the diagnosis. This…

sore throat, fatigue, and vomiting with additional a small red and green, bumpy rash under and around the arms and armpits. The infection, like HIV, attack the immune system’s T-cells. If the infection is not treated properly the patient will die due to lack of white blood cells defending the body’s immune system and blood…

Blood, in all living things, is a very complex substance that scientists are learning new things about every day. Blood is characterized as a thick substance that has variations in color depending on how much oxygen is present in the blood. If a person’s blood contains ample amounts of oxygen it will be a bright red color and if it contains a low level of oxygen the color will be a dark red. Blood composition is forever varying due to the addition and removal of all sorts of substances in the…

Goy, David The Functions of Blood Blood plays a very important role in maintaining the normal functions of the different, tissues, organs and organ systems in the body. It serves as the primary medium for carrying and transporting important gases, minerals and nutrients needed to maintain homeostasis. Blood is composed of several components: plasma, red blood cells, white blood cells and platelets. Plasma is the fluid compartment of the blood; it carries ions, minerals, nutrients, gases,…

(PNH), is a rare disorder in which the red blood cells we all carry in our bodies break apart prematurely. When this happens it is considered an acquired hematopoietic stem cell disorder. These stem sells are created in the bone marrow. These cells grow and develop into white blood cells (WBCs), platelets and red blood cells (RBCs). Hematopoietic stem cells in people with PNH are defective and produce defective blood cells. The defective red blood cells of paroxysmal nocturnal hemoglobinuria are…
