Cardiovascular System Essay Example Cardiovascular System Essay Cardiovascular System Essay Explain why you did this lab and what if any safety precautions needed to be followed. The purpose of this exercise is to gain knowledge and become familiar with the components of blood and blood cells. In order to do this, a prepared slide as well as a slide using my own blood were used. The different types of cells along with antigen-antibody reactions of the ABA and Re blood groups were understood by examining and identifying the reactions of my blood with the reagents. The safety concerns associated with this exercise are properly handling and using he microscope so as not to accidentally drop it. In order to reduce accidents while handling the microscope, use both hands to properly move and support the microscope. Other safety concerns associated with this exercise are basic lab precautions, including keeping a clean workspace, washing your hand after dealing with chemicals and blood, and using precaution when obtaining blood samples. In order to ensure that this occurs, layout the equipment beforehand In a clean sterile environment and clean the work space after experiment. By doing so, this reduces he risk of contamination or cutting yourself when using the tools. Use gloves, masks. And goggles at all times. Questions A. What are the components of blood? The components of blood are plasma, platelets, red blood cells (erythrocytes), and white blood cells (leukocytes). B. What Is the function of red blood cells? The function of red blood cells are to carry oxygen to your cells and remove carbon dioxide from your cells. They have a biconcave shape like a donuts, which allows them to bend and squeeze into the smallest of blood vessels. C. List the five types of leukocytes and describe the function of each. The five types Interruption defends the body from bacterial organisms Sinkholes defends against parasites and reduces damage from mast cells Basophilic help increase blood flow and decrease inflammation by releasing serotonin and histamines Monocots help with immune defense and rebuild damaged tissue. Produce proteins for the body and antigens, which stimulate antibody production Lymphocytes helps the body immune system. They consist of B and T cells. B cells release antibodies into the body fluids, and T cells directly attack viruses. D. What did you learn making a blood smear slide? By making a blood smear slide, the fresh blood allows for an optimal sample, preventing cellular distortion that normal occurs from prepared slides. The blood smear slide showed platelets, red blood cells, and white blood cells. Thus, the slide enabled for further learning and understanding of the components of blood and blood cells, as well as proper identification of each type of cell. Exercise 2: Blood Typing A. Describe how the ABA blood typing system works. The ABA blood typing system is a classification system for human blood, which identifies four major blood types based on the presence or absence of two antigens agglutinations), A and B substances (globetrotting), on red blood cell membranes. The four blood types are A, B, ABA, and O (lack both antigens). The presence of A and B substances on red blood cells is determined by the presence of specific alleles inherited from ones parents. The alleles are co- dominant, so a person who receives neither A or B allele is Type O blood, a person who receives only A allele is Type A blood, a person who receives only B allele is Type B blood, and a person who receives both A and B alleles is Type ABA blood. If your blood cells stick together when mixed with: Anti-A serum, you have type A blood Anti-B serum, you have type B blood Both anti-A and anti-B serums, you have type ABA blood Does not mix with anti-A and anti-B serums, you have type O blood If your blood cells stick together when mixed with anti-Re serum, you have type Re-positive blood. If your blood does not clot when mixed with anti-Re serum, you have type Re-negative blood. Everyone to know their own blood type because in case of an emergency and a blood transfusion or organ transplant is needed, it saves time and prevents further complication by knowing your blood type. If an individual is transfused with the wrong type of blood, a reaction that severely compromises the immune system can occur. Also, by knowing your blood type, you can donate blood when needed. In the case of females, knowing your blood type is also significant during pregnancy and for the unborn fetus. In cases when mothers blood type does not match the babys, it is possible that the mothers body to develop antibodies to defend against the red blood cells of the fetus. In order to prevent the fetus being born with a blood disorder because of this, knowing your blood type can help doctors create a retirement to combat the antibodies. C. Describe what would happen if type A blood were transfused into a person with type B blood. People with type A blood have A antigens on their blood cells and anti-B antibodies in their blood. People with type B blood have B antigens on their blood cells and anti-A antibodies in their blood. If type A blood were transfused into a person with type B blood, the anti-A antibodies the patient has in their blood will attack the incoming A antigen blood cells and mark them for removal by the immune system and destroy them. This would result in other complications such as, fever, hills, chest or back pain, bleeding, increased heart rate, shortness of breath, rapid drop in blood pressure, and kidney damage.
