The Cardiovascular System is composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum…

The heart muscle itself has its own set of arteries, capillaries, and veins, as does every other organ in the body. They are called the coronary arteries and veins since they encircle the heart. Coronary arteries are supplied with oxygenated blood from the aorta to the myocardium to keep contracting. The left coronary artery feeds most of the left ventricle, the septum and much of the conduction system. The right coronary artery feeds the right side of the heart, including the sinoatrial (SA)…

Describe the structure and function of the cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards.…

In the respiratory system you can found nose which is a pathway for air and this is where the oxygen get into the lung and carbon dioxide into the air .Pharynx also known as throat is an other way which air can also enter into the lungs through the mouth. Air also enters into the larynx also known as voice box. It have two main functions as it is a passageway for air to enter into the lungs and a source of vocalization. The epiglottis is a tissue a flap-like cartilage structure contained in…

cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from the lungs goes to the left atrium by the pulmonary vein. The left atrium then pumps this blood to the left ventricle. The right atrium collects deoxygenated blood from the body and then pumps this deoxygenated blood to the right ventricle. The left vertical…

Clear! The physics behind the electrical life savers, defibrillators “Defibrillation has become an integral part of the emergency response routine. In fact, the American Heart Association considers defibrillation a basic life support skill for paramedics and rescue workers.” (DIRECT QUOTE) The human heart is arguably the most vital organ of the human body, as its coordinated and controlled two-part pumping is necessary to supply blood to the entire body. This supply rate is regulated by the…

pulmonary edema are shortness of breath, difficulty breathing, and chest pain. Edema in the legs can happen from long periods of time sitting such as a long flight. Persistent leg pain and swelling could be signs of a potential blood clot in the veins called deep vein thrombosis, or DVT for short. Edema could also be the result of eating too much salty food, premenstrual…

Arterial color duplex study was performed for bilateral lower limbs which revealed mild atherosclerosis of the arteries without narrowing or blockage, no aneurysms in the popliteal arteries and confirmed the presence of a right DPA aneurysm with a small mural thrombus. Right foot toes pressure measurement showed normal readings (Fig.2). Surgical exploration was carried out under ankle block. A longitudinal skin incision was made directly over the aneurysm. Sharp dissection through fascia…

Syncope is sufficient blood flow to the brain which causes loss of consciousness which also causes fainting. It often happens in patients with hypotension which comes from the heart not pumping enough oxygen. Some of the causes of syncope is dehydration, heavy sweating, pooling of blood in the legs, exhaustion, disorder occur with exercise and with palpations or irregularities of the heart also with family history of recurrent syncope or sudden death. Risk factors are usually being…

is largely contributed to the feeble veins that elderly have. Vein quality can be contributed to many different patient characteristics as well. In many hospitals, the patients who have an IV inserted in their arm or hand are only getting their IV site assessed and flushed once per shift. There was no correlation in Salgueiro-Oliveira & Parreira’s study of the duration of the indwelling IV catheter and solely inflammation of the vein due to medications and vein integrity, although the chance of…
