The subject of Blood Cancer is very serious to me. Jamie stopped by my mom’s house over the weekend after learning that my younger brother had conquered leukemia. She asked me to tell her more about the cancer as far as what it is‚ what the symptoms are‚ and what kind of treatments are available. I told her I would explain what I know to her in the simplest way I can. I know first hand that there are three different major types of blood cancer‚ Leukemia‚ Lymphoma‚ and Myeloma. Nobody knows

Questions 1. Th e pediatrician described Jason’s pharynx‚ uvula‚ and tonsils as swollen and red. What are the four cardinal signs of inflammation‚ and how does each relate to changes in the blood vessels at a site of inflammation? Heat‚ redness‚ swelling and pain. 2. The exudate on Jason’s tonsils consisted primarily of neutrophils‚ and the CBC that was performed indicated that the number of neutrophils in his circulation was increased. What role do neutrophils play in the resolution

Leukemia usually involves the lymph nodes‚ spleen‚ and the liver. Leukemia is such complex cancer because there are many different types of white blood cells (Wbcs) that may be altered and change the rate of the way on how the cell is developing. Even though there is not an exact cause of it‚ people can

the body‚ cells are destroyed. The dying cells trigger an automatic response called inflammation‚ which includes dilated blood vessels and increased blood flow. An inflammation is the body’s equivalent to a burglar alarm. Once it goes off‚ it draws defensive cells to the damaged area in great numbers. Increased blood flow helps defensive cells reach the place where they’re needed. It also accounts for the redness and swelling that occur. Immune Cells: The Defense The defensive cells are more commonly

to the bloodstream. The lymphatic system transports a fluid known as lymph. Lymph consists of a diluted blood plasma and a large number of white blood cells. The majority of the white blood cells are lymphocytes. Lymphocytes are manufactured by bone marrow. Lymph may also contain a small amount of red blood cells. Lymph is transported around the human body travelling from the blood stream through lymphatic vessels. Passing through glands’ known a lymph nodes. As lymph travels through

Sickle-Cell Anemia is a genetic blood disorder caused by the presence of an abnormal form of hemoglobin. These hemoglobin molecules tend to aggregate after unloading oxygen forming long‚ rod-like structures that force the red cells to assume a sickle shape. Unlike normal red cells‚ which are usually smooth and malleable‚ the sickle red cells cannot squeeze through small blood vessels. When the sickle cells block small blood vessels‚ the organs are deprived of blood and oxygen. This leads to periodic

This stress hormone stimulates the release of corticosteroids from the adrenal cortex. These help to control blood sugar levels and make fats available for energy. 3. 2) Sandy and Vandita – grazed elbows – Vandita’s wound is healing quicker than Sally’s.

Function of the Spleen The majority of the spleen’s functions are related to the immune system or the blood supply. The spleen removes old red blood cells‚ called erythrocytes‚ from the blood supply and removes‚ stores and produces white blood cell lymphocytes. These stored lymphocytes produce antibodies and

hematocrit is low because the white blood cells fight infection. 2. Compare the development of lymphocytes with the development of the other formed elements. Lymphocytes have a lifetime measured in years most formed elements of the blood are continually dying and being replaced within hours‚ days‚ and weeks. 3. What is erythropoiesis? What factors speed up and slow down erythropoiesis? The specific production of RBCs that starts in the red bone marrow with a precursor cell called a proerythroblast

The lymphatic system’s most important function is to transport white blood cells that fight infection called lymph though the body. These white blood cells contain antibodies which are built to detect‚ destroy and build immunity towards pathogens and infections that enter the body. The lymphatic system consists of lymphatic vessels‚ lymphatic organs and lymph
