Functions of Blood * Blood is pumped by the heart through blood vessels‚ which extend throughout the body. * Blood helps to maintain homeostasis in several ways. 1. Transport of gases‚ nutrients‚ and waste products. * Oxygen enters blood in the lungs and is carried to cells. * Carbon dioxide‚ produced by cells‚ is carried in the blood to the lungs‚ from which it is expelled. * Ingested nutrients‚ ions‚ and water are transported by the blood from the digestive tract to cells‚ and

of abnormal cells. In normal cells the grow rate is controlled and new cells are used when the old cells die by means of apoptosis or cell suicide. When the cells do not die and continue to growth‚ it becomes cancer. This can be cause by mutation in the genes‚ radiation‚ etc. Cancer can be benign or malign. Benign cancer occurs when the growing of the cells stays in one location and malign cancer occurs when the cells destroyed the layer that covers them‚ then they enter the blood stream and can

of Thalassemia. WHAT IS THALASSEMIA? Thalassemia is genetic disorders that involve the decreased and defective production of hemoglobin‚ a molecule found inside all red blood cells (RBCs) that transports oxygen throughout the body (Miller‚ Thalassemias‚ 2008). As (Hashemi‚ 2011) says "Thalassemia is blood disorders ". As (Clinaero‚ n.d.) says" There are mild and severe forms of the disorder as well. Severe Thalassemia is often called Cooley’s anemia". There are two main types of Thalassemia

Tell Me About Blood Unit 1 Case Study June 20 2014 A&P II In this paper I will answer some questions about blood and related issues. Some of the questions I will answer are: what is the significance of a lower than normal haematocrit? what is erythropoiesis?why would the level of leukocytes be higher in an individual who has been infected with a parasitic disease. In regions where malaria is endemic‚ some people build up immune resistance to the malaria pathogen. Which

deficiency‚ loss of blood‚ bone marrow problems‚ or abnormal hematocrit. The effect of bacterial infection would cause not a decrease in hematocrit (420Allen) 2. Leukocytes are produced or stored in many locations in the body including: the thymus‚ spleen‚ and bone marrow. The two kinds of lymphocytes are B lymphocytes and T lymphocytes. Lymphocytes start out in the bone marrow and either stay there to mature into B cells‚ or they leave for the thymus gland‚ where they mature into T cells. Other formed

what measures the red blood cells in blood. Red blood cells are important for transporting iron and oxygen and for creating energy. If the red blood cell count is lower-than-normal it could indicate several diseases and problems within the body. It may be due to anemia‚ bleeding‚ destruction of red blood cells‚ leukemia‚ malnutrition‚ low iron‚ folate‚ vitamin B12 and vitamin B6 or overhydration. A bacterial infection causes white blood cells to increase‚ since they are the cells that attack and destroy

Tell Me About Blood Christina Gordon ITT Technical Institute AP2630 Dr. David Chase September 23‚ 2014 A lower than normal hematocrit or anemia means that the percentage of red blood cells is below the lower limits of normal. It could be as a result of internal bleeding‚ nutritional problem or over hydration. When there is a bacterial infection‚ the hematocrit is raised. Lymphocytes are types of white blood cells. They are the body’s primary immune defense and move through the lymph in response

Biology Lab BLOOD TYPING All blood contains red blood cells whose main job is to carry oxygen throughout the body. Red blood cells make up almost 50% of the total blood volume. They are produced in our bone marrow and not only transport oxygen‚ but they take away CO2 and other wastes. Our blood also contains white blood cells which make up only about 1% of our total blood volume. Like the red blood cells‚ the white also are produced by our bone marrow. Our white blood cells are the first response
