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 the lymphatic vessels lymphocytes are released to attack foreign bodies and toxic substances found in the system. Lymph

A vaccine is defined as “a substance used to stimulate the production of antibodies and provide immunity against one or several diseases‚ prepared from the causative agent of a disease‚ its products‚ or a synthetic substitute‚ treated to act as an antigen without inducing the disease” (“The Definition of Vaccine”). In simpler terms‚ a vaccine is an injection of a dead or weakened bacteria or virus that helps the human body produce an immunity to the said bacteria or virus. Vaccines‚ though proved

drop in the hematocrit indicates anemia‚ a lower than normal number of RBCs. An effect of bacterial infections on 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?

Hodgkin Disease Alisa Bernal ITT Technical Institute GE259 Friday 16‚ 2015 Hodgkin disease‚ also known as Hodgkin lymphoma‚ is a cancer of the lymphatic system. The lymphatic system consists of the lymphocytes‚ which are part of the immune system. The lymphatic system has lymphoid tissues‚ lymphatic vessels and lymph. The lymphoid tissues can be found in bone marrow‚ tonsils‚ stomach‚ spleen and other organs in the body. Hodgkin’s disease can begin anywhere because there are so many

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

An autoimmune disease occurs when white blood cells‚ known as lymphocytes begin attacking other cells in the body. They see these cells as a “foreign” object and attack it‚ like they would an infection or other truly foreign body that has entered the body.

In the immune system there are multiple functions happening to stop an infection or bacteria from taking over and getting the body sick. One of the most important features of this defense or system is the white blood cells. The White Blood Cells work to fight off any infection there is and have a memory function that remembers the disease to keep it away. A leukocyte‚ which is the formal name for white blood cells‚ protects the body in various ways from getting sick. The red bone marrow’s

infection may lower your hematocrit levels. 2)Compare the development of lymphocytes with the development of the other formed elements. Lymphocytes and other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Lymphoid stem cells begin development in the red bone marrow‚ but some are completed in the lymphatic tissue‚ where they give rise to lymphocytes. Myeloid stem cell begins and complete their development in the red
