White blood cell

bacteria able to produce capsule can kill a mice, where as suspension of rough colonies of bacteria devoid of capsule caused no mortality. Slime is an extracellular polymer loosely attached to the cell wall which can be easily washed off where as capsule is a compact, thick and gelatinous structure adhered to cell which is made of glycocalyx polysaccharide, glycopeptides etc.,. Capsules are usually polysaccharide in nature, may be homo/mono polymer of (glucans, dextrans, levans) or…

That is how I think of Biology, the smallest thing like a cell can do some impressive things. Biology being the study of life gives us an endless reality of changing and learning the ways of life. Taking the smallest thing like a cell has the power to change everything. The cell’s power can be used for good or for bad. Cells have the capabilities to cure the most invasive diseases. Us humans, for instance, is such a complex organism cell growing, reproducing and then dying and starting all over…

Nucleus The Nucleus is an example of a command centre found inside a eukaryotic cell; it’s usually the most prominent organelle, yet it occupies only 10% of the total volume of the cell. If this cell did not have a Nucleus, it would be defined as a prokaryote cell, however if the Nucleus was damaged and not repaired, the cell would simply die. The cell nucleus is enclosed within a double membrane (contains an Inner and Outer Nuclear Membrane) called the Nuclear Envelope, which separates the…

diagnosed with malignancies each year, with leukemia being the most common (London et al., 2014). Leukemia is a cancer that affects the child’s body by increasing the number of atypical white blood cells (London et al., 2014). Leukemia is differentiated into different types based on the change that is has on the blood cells (London et al., 2014). These different types include acute myelogenous leukemia and acute lymphoblastic leukemia, with acute lymphoblastic leukemia being the type most…

Cells have specific structures within them that allow them to carry out their functions; these structures are called organelles. Organelles have different functions within a cell that is called Division of Labor. They are also classified in two different groups, membranous and non-membranous. Membranous organelles are surrounded by a membrane while of course, non-membranous are not surrounded by a membrane. When describing the organelles and their function, first will be the membranous…

typical eukaryotic cell. A typical human cell contains hundreds of lysosomes but can be found in much higher quantities in cells more directly involved in exocytosis and cells of the immune system. Under a microscope, lysosomes can be observed as spherical-shaped, tiny membranous sacs composed of a single phospholipid bilayer that separates the acidic interior (pH 4.8-5) from the rest of the cell. The acidity is maintained by the continuous pumping of hydrogen ions into the cell, allowing for…

phlebotomy is to draw blood for lad tests. One test that is commonly used to determine ones overall health is and detect a range of disorders is a complete blood count (CBC) test. Some examples of disorders are anemia, infection and leukemia. The complete blood count (CBC) test measures multiple components and features of the patient’s blood. The information that can be collected from the test are the kinds of cells in the blood and the numbers of each cell. The types of cells that are usually…

learn about the blood, how it transport the essential substances we need such as oxygen, amino acids, nutrients, glucose and vitamins. How its used to keep the body warm, remove waste, and even regulate body fluid for electrolytes.www.kenhub.com) anatomy library. The blood is made up of three major functions. Transport, protect and regulate. The plasma is the fluid that surrounds the blood cells and helps transport carbon dioxide, hormones and metabolic waste products. Red blood cells, which are…

Differentiation and its effects on certain organelles. This writing exercise analyzes two separate but related scientific articles, “The fate of the Golgi Apparatus and the Endoplasmic reticulum During Lens Fiber Cell Differentiation” and “Coincident Loss of Mitochondria and Nuclei During Lens Fiber Cell Differentiation” both which analyze and study Lens Fiber Differentiation. The writing assignment will be based on four sections:(1) Background of the research (2) Methods used to…

complication of blood component transfusion due to the misinterpretation of symptoms, unfamiliarity of causes, and delay of standardizing methods of prevention. According to Mazzei, Popovsky, & Kopko (2008, 734), TRALI is characterized by symptoms indistinguishable from acute respiratory distress syndrome (ARDS) and usually consists of some or all of the following symptoms: Cyanosis (bluish color of skin), dyspnea (difficulty breathing), hypotension (low blood pressure), hypoxemia (low oxygen…
