White blood cell

Leukemia is a type of cancer that usually is associated with children, that affects cells in our blood. However, there is a vast number of adults who have leukemia in the U.S . Lekymiya is the lack of red blood cells which are replaced with white cells that come from the bone marrow. A numerous account of people were diagnosed with leukemia in the past year. According to the American Cancer Society, “43,000 people in the United States are diagnosed with leukemia each year”. Nevertheless there is…

Inflammation is a defense mechanism where the body’s white blood cells fight off bacteria, viruses, and damaged cells(Feeling the Heat- the Link between Inflammation and Cancer, 2013) . When pathogenic cells enter the body, the white blood cells surround that invasion site immediately(Feeling the Heat- the Link between Inflammation and Cancer, 2013) . The white blood cells then release a specific toxic chemical that denatures the pathogen enough to kill it(Feeling the Heat- the Link between…

of toxins, waste and other unwanted materials. The organs involved are the thymus, spleen, tonsils, and the appendix. The thymus gland develops the immune system, while the spleen is lymphoid tissue. The tonsils produce lymphocytes, a kind of white blood cell. The main function…

his way to the blood vessels he found himself becoming surrounded in 100s of 1000s of miniscule blood platelets, at this point Cody became very scared, he was lucky enough to be able to find a gap and escape the rapidly duplicating blood platelets that were rapidly blocking the entry of many other cells trying to find their way into the cut. After a very quick few seconds of feeling safe, Coby was stopped in his tracks by a small white cell. Coby in a state of confusion asked the cell what is…

lose their nuclei and die. The second cell type is called the Melanocytes, which produces the skin darkening pigment melanin. The cell is located in the Basal Layer of the Epidermis, the Melanosomes are relocated to the Epidermal cells. Which then makes pigmentation of the Epidermis. Melanin is responsible for different skin colours. The Merkel Cell is in the Basal Layer of the Epidermal. It is part of the reason we have the sensation of light touch. Merkel Cells are mainly found in the…

Platelets are blood cells that help our body to form clots to stop bleeding. If our blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets rush to the site of damage and form a plug, or clot, to repair the damage. Adhesion is the process of spreading across the surface of a damaged blood vessel to stop bleeding. When platelets get to the site of the injury, they grow sticky tentacles that help them adhere. Aggregation is the sending out of chemical…

system is a group of cells and tissues responsible to protect body from foreign organism like bacteria, viruses and fungi. Antibodies, one of the cells that recognize these foreign organism and will destroy them (Gale Encyclopedia of Medicine : The Gale Group, Inc., 2008). Systemic Lupus Erythematosus (SLE) is an autoimmune disease that recognize the body’s own tissues as foreign invaders. Autoimmune disease is a disorder in which the immune system fights the body’s own cells causing…

It’s made up of a network of cells, tissues and organs that work together to protect the body. One of the important cells in this system are leukocytes, or white blood cells. They’re stored in the thymus, spleen, and bone marrow. When antigens are detected, cells trigger B-cells to produce antibodies. T-cells destroy any antibodies that have become infected or somehow changed. All of these cells offer the body protection against disease (Nemours 1). These are the…

Before the inflammation stage, bleeding needs to occur. The muscle tissue is destroyed through a direct or indirect cause to the muscle. Blood is initially released into the area due to ruptured blood vessels. Inflammation is the bodys defensive system in response to an injury, it is a non-specific response (Hertel, 1997) that will prepare the wound for healing. This phase will happen a few hours post injury (After the bleeding phase has ended) (Watson, 2012). The inflammation stage can be…

body’s immune system exists in the GALT. Red bone marrow makes red blood cells and leukocytes, which are white blood cells that are part of the immune system. Two types of lymphocytes exist, B-cells and T-cells. Pre-B and pre-T cells originate from stem cells in red bone marrow. The pre-B cells remain in the red bone marrow and become B cells. The pre-T cells circulate to the thymus where they become T cells. Both B and T cells circulate to other lymphatic tissues, such as lymph nodes, where…
