abnormal white blood cells and is classified as acute or chronic (Langhorne‚ 2011). In acute leukemia‚ the leukemic or blast cells function abnormally and accumulate in the peripheral blood‚ the bone marrow‚ the reticuloendothelial system‚ and sometimes the central nervous system. It is characterized by rapid onset and may be distinguished as lymphocyctic (lymphoblastic) or myeloid (Langhorne‚ 2011). Acute lymphocytic leukemia (ALL) results from an uncontrolled proliferation of immature cells (lymphoblasts)

food with the life force still pulsating in it. OXYGEN | Wheatgrass Juice is mostly chlorophyll and when consumed it will boost the hemoglobin production and help the body carry more oxygen in the blood. Wheatgrass Juice builds red blood cells and activates white blood cells‚ which cleans the blood and boosts the body’s immune system. Since Wheatgrass Juice is so rich in chlorophyll‚ ingesting it is an efficient way to get this power and energy of the sun into our bodies. ENZYMES | Wheatgrass

marrow Why we discuss myeloid tissue/bone marrow? – because we want to study the development of blood cells. We called it HEMOPOEISIS/HEMATOPEISIS HEMOPEISIS/HEMATOPOEISIS –Blood cell formation (occurs in the bone group) Why study this? Because: there is a continuous replacement of cells they have short life span when they are in the peripheral circulation so‚ we have to study how these cells mature and differentiate Phases of hematopoeisis MESOBLASTIC PHASE (Prehepatic or primordial

In solution hypotonic to the sheep’s red blood cells‚ the red blood cells will lyse‚ as a result of the water entering the cell via osmosis. First‚ a stock solution of NaCl was prepared at concentration 1.0M. Working solutions were made ranging from hypotonic to hypertonic with a negative control at isotonic solution (150mM). The solutions were diluted up to 4 mL into 5 test tubes‚ (0mM‚ 0.13mM‚ 0.15mM‚ 0.17mM‚ 0.3mM 0.5mM) using distilled water to dilute the stock solution. The working solutions

Rob enters the Vena Cava and enters the right Atrium where he is then pushed through the Tricuspid Valve and into the right Ventricle. While in her he currently has no oxygen in his biconcave dome so he needs to go and get some. He goes through the Pulmonary Valve and up and out of the Pulmonary
