One of the functions of the cardiovascular system is to transport oxygen and remove carbon dioxide from our body…
The main parts of the cardiovascular system are the heart, blood and the blood vessels (arteries and veins). The function of the heart is to pump blood around the body. The function of the blood is to supply nutrients and oxygen to the cell. The blood vessels (arteries and veins) role is to transport blood to and from the heart. However, the general function of CVS is to remove waste products such as CO2 and protect the body, for example the white blood cells in the body. “It also distributes heat around the body and assists in temperature regulation and helps regulate water.”…
The myocardium, commonly referred to as the heart, acts as a pump for transporting blood around the body via a collective system, known as the cardiovascular system. This system has various components; blood vessels; mainly arteries, veins and capillaries. The cardiovascular system has four main functions within the body. Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Secondly, to protect the body from infection and blood loss. Thirdly, to distribute heat around the body to enable a healthy temperature of 37oc and finally to aid the body to maintain fluid balance. This ‘human pump’ can be regarded as two pumps. The fist sized organ contains two muscular chambers; the upper chamber; the atrium and the lower; the ventricle. The right side of the heart pumps deoxygenated blood from the veins to the lungs for oxygenation, whilst the left side pumps oxygenated blood from the lungs to the body. It is important to note that the two sides are separated by a septum. The blood flows through the heart twice within one cycle, this is known as ‘double circulation’.…
Heart is associated to cardiovascular system, heart is also known as the blood-pump of the body. It pumps blood through the circulatory system to all parts of the body. The blood carries food and oxygen to the cells and carries away carbon dioxide and waste materials. The right hand side of the heart receives de-oxygenated blood from the body tissues, and pumps it to the lungs. The left-hand side of the heart receives oxygenated blood from the lungs and pumps it into the body, so that the oxygen can be delivered to cells.…
The cardiovascular system has a role of circulating blood around the body. The contents of blood being circulated include nutrients, gases and waste products. The main organs involved within this process are blood, arteries, veins, heart and the lungs.…
Sickle Cell Disease affects the Red Blood Cells (RBC) in the body. Sickle Cell is caused by a mutation in the genome where GLU is replaced with VAL, changing the structure and denaturing the protein. This causes the RBC to sickle. When the RBC is sickled, it is not as efficient in carrying oxygen or moving through the bloodstream.…
The cardiovascular system, also known as the circulatory system, is composed of the heart, blood vessels, and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough, elastic tubes called arteries, which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries, which have such thin walls, that oxygen, nutrients, minerals, and other substances pass through to surrounding cells and tissues. Waste substances flow from the tissues and cells into the blood for disposal. The capillaries join and enlarge to create tubes that eventually become veins, which take blood back to the heart. Vessels carrying oxygenated blood (usually arteries) are shown in red and those carrying deoxygenated blood (usually veins) are blue.…
Sickle Cell Anemia, also known as Sickle Cell Disease, is a disease that causes the production of abnormal hemoglobin. The red blood cells (RBCs) carry oxygen to organs and tissues. Hemoglobin, a molecule in the RBCs, is a protein that attaches to the oxygen in the lungs and carries it to all parts of the body. Hemoglobin takes on the oxygen, and releases carbon dioxide, a process known as oxygenation. In the tissues, deoxygenation occurs where the processes is reversed, when hemoglobin releases oxygen and takes on carbon dioxide. When the RBCs are healthy, they can easily move through the tiniest blood vessels throughout the body because of their flexibility. The hemoglobin S is fragile and abnormal in Sickle Cell Anemia, and the RBCs are pointy with a shape like the alphabet letter "C" or the crescent moon. This makes the RBCs difficult to move pass through the blood vessels. The RBCs become hard, and can get stuck in blood vessels, and often clog the spleen. This causes pain, infection, and poor blood flow in patients that have Sickle Cell Anemia. The RBCs also block blood flow to organs, such as the heart, lungs, brain, etc., which can lead to stroke, damage to organs, especially the spleen, acute chest syndrome, disability, and sometimes, even death.…
Almost all patient care is based upon treating and managing the symptoms that accompany sickle cell disease. Sickle cell disease severity varies from patient to patient making it hard to predict which patients will respond adequately to certain treatments. Individuals with severe complications from the disease itself would benefit best from aggressive treatments such as transplantations. Severe complications include pain, splenic crisis, acute chest syndrome, pulmonary hypertension, and stroke.…
the supply of oxygen gets cut off. A normal blood cell lives up to 120…
There have been many researches and tests done on the genetic causes of Sickle Cell Anemia and how it developes, as well as it's effects on the circulatory, muscular, and respiratory systems, as well as it's effects on the joints and other systems of the body, and the complications associated with them. Most of the research has been done to explore on the reasons why it mostly effects the African-American community and people who are from the West Coast of Africa. It has also been known that Sickle Cell Anemia also effects people from the Mediterranean countries (Wethers, 2000)…
In the three scenarios given in the text, there are examples of three signs of different blood disorders. Each of these three people shows symptoms of being at risk for a type of blood disorder. The first scenario: Amy, a 4-old Caucasian female, has been complaining of being tired all the time. She is pale and a picky eater. Her mother is a single mom with a small budget to feed a large family. Amy only eats pasta, breads, and hot dogs, and drinks only artificial fruit punch (Axia College, 2011, Week 4 Supplement).…
Sickle cell disease (SCD) is a group of inherited conditions that affect the red blood cells. People affected with sickle cell disease produce abnormally shaped red blood cells that causes health problems. Sickle cell disease is caused by a defective gene passed on from the parent to the child. Sickle cell disease is condition that is considered serious and lifelong.…
Sickle Cell is an inherited blood disorder that affects approximately 100,000 people in the United States. Red blood cells contain hemoglobin which is a protein that carries oxygen through the blood. Normal red blood cells are flexible and round. This allows them to travel through the small blood vessels and deliver oxygen to all of the body. Sickle cell disease(SCD) causes these red blood cells to form into a crescent shape, like a sickle. The sickle-shaped red blood cells easily break apart, causing anemia. Sickled red blood cells only live 10-20 days instead of the normal 120 days. The damaged sickle cells then clump together and stick to the walls of blood vessels, causing a blockage of blood flow. This can cause severe pain and permanent damage to the heart, brain, kidneys, lungs, bones, liver and spleen. Severe pain is called acute sickle cell crisis. Exactly what brings on the pain is undetermined, but infection and dehydration are common triggers (Powars, 2013).…
