The body is continuously making red blood cells to replace the old ones. When a person has sickle cell disease, the body may have difficulty creating new red blood cells at the rate with which they are being destroyed. “Because of this, the number of red blood cells is usually lower than normal,” which is a condition called anemia (U.S. Department of Health…,…
The functions of a bone are support, protection, attachment site for muscles making movement possible, storage of the minerals, calcium and phosphate or mineral homeostasis, blood cell production occurs in red bone marrow called hematopoiesis, and energy storage in yellow bone marrow.…
Based on the extensive research conducted on the samples of the water at various locations and of the victim’s bodily fluids, it is evident that the location of the drowning was at Duck’s pond. The most reliable test for diatoms in an autopsy of the body would be a bone marrow extract. This is because the diatoms present in the bone marrow are guaranteed to have come from the liquid inhaled during drowning. This is not true for the other diatoms found in the body which came from extractions of soft tissue organs such as Euglena, Anabaena, Vorticella, Volvox and more. The only diatom present in the victim’s bone marrow extract at the time was Synedra.…
Some bones contain bone marrow whereas others the bones marrow produces blood cells that are vital for the body The bones cells are called osteocytes, these cells are located in the matrix on rings which are known as lamellae, the rings system is called osteone or a haversain system. It is in the osteone where the blood vessels and nerves pass through the hollow centre. The responsibilities of the bones is to allow tendons to attach themselves to them, provide support for soft tissue to defend them from injury, for example the ribs shelter the heart and the lungs to protects them as they play an important role in the body. Compact bones What is compact bone?…
Red bone marrow produces white blood cells which aid in the immune system, as well as red blood cells which circulate and carry oxygen throughout the body. Bones are also a good storage for various minerals such as calcium and phosphorus. Bones absorb and release minerals as the body needs them. Yellow bone marrow found in bones is used to store energy reserves. Some bones also help our senses such as how the bones of the middle ear transmit vibrations to the inner ear and…
Myelodysplastic syndromes, also known as MDS and pre-leukemia, are a group of disorders caused when the production of white blood cells, red blood cells, or platelets is interrupted (Myelodysplastic Syndrome Treatment 2016). These syndromes are rare, fewer than 14,000 cases of myelodysplastic syndromes occur in the United States each year (Statistics about Myelodysplastic syndromes). Blood cells and bone marrow do not fully develop or become mature enough to function properly when a person has myelodysplastic syndromes. Blood cells not becoming mature can cause many problems. If the white blood cells, the blood cells that fight infection, do not work properly infections will be more prevalent.…
Osteoblasts are bone cells and their purpose is to absorb calcium from the blood and lay it down in the cartilage as small plates. The plates start in the middle of the long bone in the area known as the primary centre and are laid out in both directions toward the ends of the bone, making it…
There is a research that is known as stem cell research that could lead to several medical and scientific revolutions, but numerous people argues that stem cell research is unethical and it stirs up many conflicts with religious groups. Stem cells are very unique cells that have the potential to perform various specific tasks. Many of the common people argue about the ways to retrieve the stems cells. There are also countless advantages and disadvantages of stem cell research. Is stem cell research right or wrong?…
Comparison of Ivory in “Sister” with Ethan in “Close to the Bone” Introduction Andrew Lam authored Birds of Paradise Lost, which is a series of short stories capturing the experiences of the American immigrants from Vietnam. In these stories, versions of paradise are both lost and gained. The experience is solely that of the Vietnamese refugees who fled Vietnam for America and other places in 1975 during the fall of Saigon. Lam’s stories depict the experience of the refugees; the vivid pursuit of the American Dream, the struggle that leads to transformation, mediation, and forms new ways of being in a foreign land. The story is narrated repeatedly in a convincing and a non-apologetic manner, regardless of how stereotypical the characters are…
The most common problem is the sickle cell shaped red blood cells that get stuck to the blood vessels, blocking blood flow, in results causing certain conditions. One condition is Hand-Foot syndrome, which is, when the foot and hand have pain, swelling and fever. Another condition is “sickle cell crisis”, this is a painful symptom that a person experience sudden body, organ and joint pain. This is due to when the sickle blood cells block oxygen flow to the tissues. This crisis can last a few minutes to weeks causing the patient to be hospitalized.…
Components Of Blood Blood is a specialized body fluid. It has five main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, transporting oxygen and nutrients to the lungs and tissues, forming blood clots to prevent excess blood loss, carrying cells and antibodies that fight infection, bringing waste products to the kidneys and liver, which filter and clean the blood, and regulating body temperature. The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells.…
Bone Grafting Bone grafting is a surgical procedure to repair defective bones or certain types of broken bones. In this procedure, pieces of bone or a type of man-made (synthetic) bone is used to strengthen a broken bone or to fill in a defect. There are three basic types of bone grafts. Your graft may be from: • Your own bone (autograft).…
I volunteered for the University of Minnesota Group I am involved in called Be the Match on October 1st from 10-11 at Coffman Union before and during the Saving Second Base 5k. This group I’m in is interested in signing up a diverse mix of people to the bone marrow registry to save those with blood diseases. While what we do is all volunteering based and not in hospitals being the ones taking others bone marrow, we learn about the donation process. As regards to safety during the bone marrow donation process, they sterilize your arm or the area around your pubic bone depending on the type of donation needed. The nurses make sure there is no contamination in the area where the needle is inserted.…
Writing in the Biomedical Engineer Field Writing is a universal language in communicating information to one another. It is used every day to keep track of simple tasks and information in our busy lifes. Writing comes in a variety of different methods, from a shopping list, to a proposal on the newest pacemaker on the market; therefore, we change our method of writing to meet the intended audience. Every field of study has its own ways of writing.…
Sickle cell anemia is a genetic blood disorder that causes normal red blood cells to form into an irregular shape, called sickled-cells. The sickle cell gene causes the body to produce abnormal hemoglobin. After a while, the hemoglobin will then cluster together anywhere in the body causing the blockage of blood flow through the blood vessels. This blockage deprives the tissues and blood of oxygen which can lead to many difficulties and problems. SCD becomes life-threatening when the damaged red blood cells begin to breakdown, when the spleen does not work properly or at all, or when it is unable to prevent infections from coming in.…
