INTRODUCTIONS Blood is a fluid connective tissue that circulated around the body. Blood is primarily used to transport medium for the maintenance of homeostasis (Mader, 2010). Blood transports oxygen and carbon dioxide, nutrients and wastes, metabolic substrates and hormones between organs and tissues. Blood also involves in defending against the pathogens and infections, and blood loss. Blood helps to regulate the body heat, maintain its own water-salt balance, and provides a buffer for acid-base balance. Blood consists of formed elements including erythrocytes (red blood cells), leukocytes (white blood cells), and platelets that are suspended in plasma (Sherwood, 2012). Blood cells are produced in the red bone marrow from the undifferentiated …show more content…
The buffy coat on above the packed red blood volume contain white blood cells and platelets. Plasma have the most percentage in the total blood volume. The kidney produced erythropoietin hormones that stimulates the production of red blood cells in the red bone marrow known as the erythropoiesis process (Mader, 2010). Erythrocytes (red blood cells) are essentially for transport oxygen and carbon dioxide for gas exchange. Red blood cells are lack of nucleus. They contain the hemoglobin which mainly bind to oxygen to transport it to tissues. The red blood cells have the average life span of 120 days and destructive by the spleen and liver. The degraded haemoglobin, iron, and bilirubin are recycled. Nutrients such as vitamin B12, folic acid, and iron are required for the erythropoiesis. Leukocytes or white blood cells have a nucleus and either granular or a-granular (Mader, 2010). Leukocytes are translucent and observed through staining. The granular leukocytes are neutrophils, basophils, and eosinophils. Neutrophils are neutral or no dye color and have more than 3 lobes nucleus (Sherwood, 2012). Eosinophils have the affinity of the red dye eosin and basophils is observed to have the blue dye.
In Blood In Blood Out is a drama directed by Taylor Hackford, and starring Damian Chapa (Miklo), Benjamin Bratt (Paco), and Jesse Borrego (Cruz), produced by Hollywood Pictures. The film was based off everyday life in East Los Angeles, from the 1970’s through the 1980’s. Damian Chapa stars as Miklo in the film, a Mexican-American who wanted to be accepted, not by his skin but for the Mexican within him. Benjamin Bratt (Paco) was the older cousin of Miklo, who learned his lesson throughout the movie and changed his ways. Jesse Borrego (Cruz) is the step-brother of Paco who was a talent artist, who ended up turning to drugs because of back problems caused by a rival gang incident.
Three hundred and thirty-four years later in the future, Carl Landsteiner, a Viennese doctor, performed a very simple experiment with blood in 1901. During his experiment, Landsteiner noticed "clotting in some samples of mixed blood and not others". (Tucker, 10) Landsteiner separated his samples into three groups: A, B, and C, according to how they clotted in his experiment. Today, the blood type C is known as type O blood. When Landsteiner was grouping these blood types, he happened to look over type AB. AB occurs in about 3 percent of the population. Later in 1907, two researchers, Jan Jansky in Czechoslovakia and William Lorenzo Moss in the United
The largest component of the blood is the Plasma, a liquid substance made up of 91.5% water and 8.5% solutes that is responsible for over half the blood’s total volume. This liquid portion of the blood is vital for maintaining blood pressure within the body that helps capillary exchange. (Tortura 691-692). Cases of hemorrhagic or hypovolemic shock, a severe reduction in plasma is what triggers the body’s feedback systems, and compensation for fluid loss will stem from pulling of water from other
Racism, a plague in our society that has infected our society, and still does today, has been rooted by the premise of Darwinian evolution. Racism existed long before Charles Darwin made his mark in history; however, in the book One Race One Blood, the authors explain how there is a very close relationship between the theory of evolution and what we know today as racism. The authors intent of this book is to realize the effects of a specific ideas that has shaped racism. Mr. Ken Ham describes ideas as being seeds, “…they might seem small; they might seem insignificant; they might even go unnoticed by all expect those who hold them in the moment…” (7). Charles Darwin’s idea (or seeds) of his evolutionary has taken root and made its way into public schools, the government, and even our churches. Although, racism did not originate with Darwin, Ken Ham claims that, “he did more than any other person to popularize it” (22). His evolutionary ideas have fueled racism and this is what racists use to justify their hatred toward those who are different from them (8).
Red blood cells deliver the oxygen to the muscles and organs of the body.
Blood types can be categorized in many different ways. Karl Landsteiner categorized “the first three blood groups…[as] A, B and C (subsequently renamed O from the German word “ohne” which means “without”)” (Franchini 1545). Each of these blood groups also have unique properties that give the blood an inability to mix with other blood types. For example, Landsteiner has found out that type-A red blood cells contains an A-antigen and anti-B in its serum (Franchini 1545). Type A blood contains the monosaccharides N-acetylglucosamine, galactose, fructose, and “a N-acetylgalactosamine attached to galactose” (Timberlake 556).The A-antigen is used as an identifier for the body to determine whether something in the bodies system belongs or ...
The spleen stores blood. The spleen is made up of two types of tissue which consist of the red pulp and white pulp. The function of the red pulp is to store and remove red blood cells. The white pulp consists of localised areas of lymphoid tissue within the spleen and produces the lymphocytes. ( Reeder et al., 2009).
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
Many people throughout the world visit the United States every year to receive medical treatment. This is due to our excellent pharmaceutical industry as it spends million of dollars and many hours of research to come up with what we can only describe as “miracle” drugs and treatments. Part of the success of many of these medications is because the pharmaceutical industry is highly regulated by policies that protect the public from accessing drugs that have not been fully tested and found to be “safe”. However, this was not the case until the late 1990s and early 2000s. One time in history that highly influenced the strict regulations we currently have was the nationwide contamination of patients through blood transfusion or by consuming medications
To understand where and how leukemia occurs it helps to know a little about the blood and lymph systems. Bone marrow is soft inner part of the bone where blood cells are formed There are three different types of major blood cells; white blood cells, red blood cells, and platelets. In infants active blood cells are found in almost in all bones but by the teenage years they are found in mostly flat bones (skull, shoulder blades, ribs, and pelvis) and the vertebrate. Bone marrow consist of a small number of blood stem cells, more mature blood forming cells, fat cells, and supporting tissues to help the tissue grow. They go through a series of changes to make new blood cells. With this process 1 of 3 things is made- red blood cells, white blood cells, or platelets. Red blood cells carry oxygen from the lungs to all the other parts of the body and transport carbon dioxide back to the lungs. Platelets are cell fragments made by a type of bone...
There are three different types of granular leukocytes. Neutrophil is a phagocyte, produced in the bone marrow that ingests and destroys bacteria extremely fast. Neutrophil has a diameter, which is, about ten to twelve micrometers long. They make up about 60-70 percent of the total number of white blood cells in our body. Eosinphil is a type of white blood cell that secretes poisonous materials in order to kill parasites, allergies and phagocytosis of bacteria, which is when the...
Red blood cells are carriers of oxygen. A percentage of these cells contain hemoglobin, which has the capacity to combine with iron. It's the iron-hemoglobin molecular structure that helps carry oxygen-rich blood from the lungs to your tissues and in return, delivers carbon dioxide back to the lungs to be expelled. A CBC with Differential that shows low red blood cell levels can indicate anemia. RBCs comprise about 40% of total blood volume; the RBC count is the number of red blood cells per cubic millimeter of blood (Rauen, 2012). Normal red blood cells values vary a...
Blood transfusions are potentially life-saving procedure that can help replace blood lost due to surgery or injury. Every two seconds someone in the United States needs blood (Blood Facts 1). Blood has been used as a form of therapy for a variety of ailments dating back as far as the 17th century. There is no question that blood is an incredibly valuable resource. Over the years, there have been several significant advances made in not only the research of blood but also medicine. The history and research of blood transfusions has brought the discovery of blood types and the incompatibilities of said blood types.
Blood group AB has both A and B antigens located on the surfaces of red blood cells, however not located in the blood plasma. This particular blood group may receive blood products from group A or B but not permitting to donate to any other blood groups besides AB.
I will be investigating Human Blood as my specific tissue and giving an overview on the location, characteristics, and the benefits it has to the human body. Blood is extracellular matrix that is consists of plasma, red blood cells, platelets, and white blood cells. Blood is located within the capillaries/veins/arteries of the human body, which are blood vessels that run through the entire body. These blood vessels allow the blood to flow smoothly and quickly from the heart to distinct parts of the human body. The unique parts of human blood all work together for a purpose: the Red Blood Cells(erythrocytes) transports oxygen throughout the body, White Blood Cells(leukocytes) play a part in the bodies immune system, Platelets(thrombocytes) assist in creating scabs,
