Tell Me About Blood 1.) What is the significance of lower-than-normal hematocrit? Lower-than-normal hematocrit indicates anemia. People with anemia do not have enough hemoglobin‚ which is the oxygen-carrying protein in red blood cells. Iron‚ B12‚ and folic acid deficiencies‚ some medications‚ and pregnancy can cause anemia. There are also more serious causes such as problems with the immune system that cause destruction of red blood cells earlier than normal‚ chronic diseases including

Morphology of Human Blood and Marrow CELLS 1. Describe two main differences between neutrophilic band and neutrophilic segmented cells. Peripheral blood of a healthy individual contains 2% to 6% of the band neutrophils. They have a nucleus with a horseshoe or sausage shape they do not have a nucleus separated into lobes connected by a filament. The nuclear chromatin is clumped they stain various shades of pink and contain alkaline phosphatase. In normal peripheral blood of older adults they have

multicellular organisms‚ the cells that make up their respective organisms have different structures depending on their function. The process in which cells get specialized is known as differentiation. Unspecialized cells‚ known as stem cells‚ can be called upon to replace damaged or aging tissues‚ or create new tissue for growth. An example of specialization can be found with blood cells. Every blood cell originates from the bone marrow‚ starting as a unspecialized stem cell known as a multipotential

The cells of the adaptive immune system are special types of leukocytes‚ called lymphocytes. There are two main types of lymphocytes‚ B cells and T cells‚ which are derived from hematopoietic stem cells in the bone marrow. T cells are involved in cell-mediated immune response‚ whereas B cells are involved in the humoral immune response. The surface of each lymphatic cell has receptors that enable them to recognize foreign substances. There are two major subtypes of T cells: the helper T cell and

which research methodology the authors used. The research methodology that was used was a spray on reagents to locate blood spatter that’s too small to see. Because chemicals can contaminate evidence or give false positive‚ an infrared camera system that exposes microscopic traced of blood without using chemicals. It is use to target blood protein which remain long after visible blood which may have been wiped away‚ also filtering the background infrared to revel bold residue that can’t be seen with

Journey of a Red Blood Cell The Circulatory System is the main transportation for the body‚ made up of blood vessels‚ the blood and the heart. The blood is comprised of the red blood cells‚ white blood cells (lymphocytes and phagocytes which make up part of the immune system‚ engulfing invading pathogens)‚ platelets which help the blood to clot preventing infection all transported around the vessels amongst the plasma. The blood plasma contains dissolved substances including carbon dioxide‚ urea
