Brochure information Anatomy and physiology of the cardiovascular system Cardiovascular System According to (smith.A2013). The cardiovascular system includes the heart, blood vessels and also blood. Its role is to deliver nutrients and takes away any by-products from a person’s body. The cardiovascular system is the heart and it is a four-chambered pump that carries blood to the arteries these arteries then carries out clean and oxygenated blood to the tissue. The blood Definition According to (dictionary.com 2002).
Other conditions that cause anemia are HIV/AIDS, cancer, kidney disease, and sickle cell anemia. Primary polycythemia is caused by unregulated erythrocyte production. Polycythemia may occur because of hypoxia. When this occurs the body senses low oxygen levels and produces more erythrocytes to carry more oxygen to the body
CIRCULATORY SYSTEM 1. INTRODUCTION The circulatory system is also known as the cardiovascular system. This system is a double circulatory closed system which transports blood via arteries, veins and capillaries to the lungs through the pulmonary circulation and to the rest of the body tissues in the systemic circulation. Since the blood travels to varying distances around the body, the blood vessels have to be adapted to overcome different pressures. The pressure changes in the four chambers on the heart (two atria’s and two ventricles) allow the blood to continuously flow in one direction.
Introduction: Left ventricle hypertrophy can cause congestive heart failure to the patient. Common cause of the disease is due to the hypertension. If left ventricle hypertrophy is untreated, it will easily causes congestive heart failure. Abstract: The reasons that why I setup this hypothesis is because the patient have chest pain, this pain may come from congestive heart failure. Besides, the patient has medical history, such as hypertension and diabetes which increase the chance of chronic heart failure.
The human heart pumps blood through the arteries, which connect to smaller arterioles and then smaller capillaries. In this assignment, we will discuss the arterial blood pressure from several aspects, include definition, normal values for blood pressure, the most important factors affecting it, the mechanism involved in arterial blood pressure regulation, and the relevance between the pressure and the eye. Definition of blood pressure, it’s Normal value, and the factors that determine arterial blood pressure under physiologic conditions. Blood pressure refers to the force exerted by the blood against the inner walls of the blood vessels . This pressure produces when the heart contracts during the heartbeat cycle, which forces blood out
The ventricles then contract, the valves between the atria and ventricles close and the blood is pumped into the aorta and pulmonary artery. Explain the term blood pressure and describe the role it plays in the circulatory system. Describe the conditions high and low blood pressure. According to Blood Pressure UK, when your heart beats it pumps blood around your body to give it the energy and oxygen it needs. As the blood moves, it pushes against the sides of the blood vessels.
Remington Stotler Advanced Adult Care Pre-clinical assignment Common Conditions: 1. Acute myocardial infarction/coronary artery disease is when the arteries that supply the myocardium are clogged up; the heart cannot pump blood effectively to adequately perfuse vital organs and peripheral tissues. It affects the arteries that provide blood oxygen, and nutrients to the myocardium. When blood flow through the coronary arteries is partially or completely blocked, ischemia and infarction of the myocardium could occur. Nitroglycerin (NTG) increases collateral blood flow, redistributes blood flow toward the sub endocardium, and dilates the coronary arteries.
Organs [MacGill (2015)] Lymph: It is a fluid that is derived from blood plasma. It passes from capillary walls to the arterial end. Whenever tissue fluid started to accumulate, the lymphatic vessels collect it and remove it and returned to the blood. By this action it prevents it
The top number is systole and the bottom is diastole. Diastole is the reading when the heart is relaxed and systole is when the ventricles of the heart contract (the working phase of the heart) Hypertension (high blood pressure) is blood pressure that consistently remains above the normal level of 120/80. Things such as stress, kidney disease, smoking, too much alcohol and bad diet can cause high blood pressure Hypotension (Low blood pressure) is when the blood pressure constantly remains below the normal level of 120/80. Things such as shock, haemorrhage, burns, some types of medication, dehydration, anaemia and allergic reactions can cause low blood
It is nestled between the lungs and the mediastinum. Because of where the heart is located some can feel the heart with the palm of their hands if they apply pressure under the sternum. The heart delivers blood to our entire body. In order for the heart to pump efficiently it contracts and relaxes in intervals to allow the blood to be successfully pumped to all of the cells, organs and tissues. This is called systolic and diastolic pressure.
