The river of life, the blood is the body’s primary means of transportation. Blood is a part of the hematopoietic system, which also includes lymphatic tissue, bone marrow, and the spleen. Blood is a complex transport medium that performs vital pick-up and delivery services for the body by picking up food and oxygen from the digestive and respiratory systems, and delivering those vital elements to different cells of the body. In exchange of the blood and oxygen, blood then picks up wastes from the cells for delivery to the urinary organs. These functions could not be provided for the individual cells without the blood. Like any other structure of the body, blood can be attacked by many types of disease, such as Leukemia. Leukemia is a general name given to a number of blood cancers that affect the blood.
Blood transports hormones, enzymes, buffers, other types of biochemicals that are important in body functions. The blood is made of plasma and formed elements. Plasma is the clear, straw-colored fluidpart of the blood. The formed elements consist of red blood cells, white blood cells, and platelets. The red blood cells (erythrocytes), play a critical role in transporting oxygen and carbon dioxide to various parts of the body, and play an important role in the homeostasis of the acid base balance of the body. The white blood cells (leukocytes), are responsible for cellular defense (phagocytosis of pathogenic microorganisms), humoral defense (secretion of antibodies involved in immune system response and regulation), and play a role in the body’s inflammatory response (secretion of Heparin and Histamine). Platelets play an important role in homeostasis of the blood and the coagulation (blood clotting).

Blood is a specialized body fluid that delivers necessary substances to the body's cells — such as nutrients and oxygen — and transports waste products away from those same cells. It can be referred to as a liquid connective tissue. It consists of solid elements made up of RBCs, WBCs and platelets (commonly referred to as the formed elements of the blood), suspended in a fluid medium, plasma which contains, water (about 92%), dissolved proteins, lipids, glucose, mineral ions, hormones, organic acids, urea and other wastes,
Blood is a tissue that is circulated within the body to assist other parts of the body. This connective tissue has specialized cells that allow it to carry out its complex functions
The Hematologic System is regarded as the body’s system that regulates the movement of nutrients, molecules (macro and micro molecules), and oxygen to tissues and metabolic waste products and carbon dioxide out of the tissues (Colbert, 2009). The overall role of the hematologic system is to deliver substances needed for cellular metabolism, temperature regulation, defend the body from injury and microbial infections, and maintain the homeostatic balance or acid-base chemistry of the blood and fluid-electrolyte balance. The Hematologic System is principally made up of the blood, blood vessels, and primary organs that manufacture blood cells such as the bone marrow, spleen, lymph nodes, liver, and thymus gland (Ignatavicius & Workman, 2009). Blood is made up of three distinct components: red blood cells, white blood cells, and plasma, and its role is to transport necessary substances for metabolism (nutrients, hormones and oxygen) to cells and to remove metabolic waste products and carbon dioxide, regulation of body temperature and fluid balance, and protect the body from infections. Blood vessels simply aid the transportation of blood throughout the body, simply in and out of the heart. Spleen on its part is the largest lymphatic organ and functions as the blood filtration system and reservoir, site for fetal hematopoiesis, and mounts immune responses that act against invading infections. Bone marrow is another important component of the hematologic system, and its role is to synthesize new blood cells (Red blood cells white blood cells, and platelets) that constitute a healthy blood count while the liver functions by detoxifying the blood (Colbert, 2009).
According to Virtual Medical Centre (2014) the primary function of the blood is to act as a transport, to give the body protection and to help regulate. The blood dissolves gases such as oxygen and carbon dioxide. The blood also transports vital nutrients throughout the body, such as micro-nutrients, fatty acids and amino acids. The flow of the blood helps to regulate the body’s temperature. Also the blood removes wastes material of metabolism. Blood cells (white and red cells) are carried through the body to help with the body’s natural defense, blood clotting and the carry anti-bodies.
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.
The public health issue the organization is working to address is to find a cure for blood cancer. At an estimated amount close to 1,012,533 people in the United States are have been diagnosed with leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma, and myeloma. A majority of the diagnosed are living with or are in remission. According to LLS, every four minutes someone new is diagnosed with blood cancer and approximately every 10 minutes dies from blood cancer.
What is Leukemia? Leukemia is a cancer in blood forming cells that are in early stages of development. Most of the time the white blood cells, but some types of leukemia start in other types of blood cells. Blood cells are form in bone marrow. Any of these cells can turn into a leukemia cell, once this happens the cell does not mature like it should. The cell may start to produce rapidly and the mutated cells probably won’t go through apoptosis like they should. These cells build up in the bone marrow and crowd out the healthy cells. Typically, leukemia cells get into the blood stream rather quickly. From the blood stream they can spread to places like lymph nodes, spleen, liver, central nervous system or other organs where the leukemia cells can cause those other cells to function irregularly.
Leukemia like any other cancer is devastating especially when it affects children and especially when they are too young to understand most of what is happening to their bodies. Facts like these are what should be used to motivate researchers and caregivers to help to make the process of treatment and care for patient dealing with disease one that is pleasant and supportive. The research should be taken seriously and it is hoped that in the future a cure can be found and the cause of the disease can be explained. It is also hoped that achievements like those can give families who are coping with disease or who have lost loved ones to the disease can find closure and solace in knowing that other may not have to go through what they have.
The body's blood consists of many components, red blood cells, white blood cells, plasma, and platelets. Red blood cells deliver oxygen to your body and remove waste. Without them, your body would slowly die. They contain a protein chemical called hemoglobin, which gives it it’s red color. Also, hemoglobin contains Iron, making oxygen molecules attach to it so as the blood passes through tissue...
The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
Between the ages of one and fourteen, one of the three most common reasons for fatality is cancer (. Though the types of childhood cancers are endless, the most frequent one is leukemia, which is a cancer of the blood cells. This occurs when the number of white blood cells is abnormally high and the number of red blood cells and platelets are abnormally low. In a normal blood sample the red blood cells greatly outnumber the white blood cells, making up about half of blood components in itself. When a patient has leukemia, the white blood cells increase greatly and the red blood cells decrease, causing an inability to transfer the necessary amount of oxygen throughout the body. In youth patients there are two major types of Leukemia; the ...
Blood platelets help play out coagulation. White blood cells are a big help and play a huge role in the immune system. Red blood cells transport oxygen and carbon dioxide back and forth throughout the body. Because blood is made in the bones, it is considered a type of connective tissue (Components of the Blood). There are three blood types. There are red blood cells, white blood cells, and platelets.
Leukemia is a cancer of the white blood cells. It begins in the bone marrow, the soft tissue inside the bones. Within the bone marrow is where white blood cells are created, that help fight off bacteria, viruses, and other microorganisms within the body that cause infections. The disease develops to when the white blood cells are being produced out of control. The cells that are being produced do not work properly as they should, they grow faster than a normal cell would and don’t know when to stop growing. Overtime, if not treated properly, the white blood cells will over crowd blood cells, creating a serious problem such as anemia, bleeding and infection. Leukemia cells can spread to the lymph nodes and other organs in the body causing swelling and pain.
Our blood is able to connect all our organs together to create one organism and is able to transport the most vital and important molecules through these blood streams. Hence, blood cells are needed for immune system function and metabolic functions.
According to KenHub, the blood consists of cells, cell fragment and an aqueous solution(plasma).45% of blood are red blood cells, white blood cell and platelets and the rest are plasma which consists of water, plasma protein and
