Transposition of the Great Vessels Transposition of the great vessels is a heart condition that is present in infants at birth and often known as a congenital heart defect or the more common term is the transposition of the great arteries(TGA). TGA is when the two main arteries, the pulmonary artery and the aorta, are switched in position, or "transposed". As a normal heart, deoxygenated blood returning to the heart from the body is pumped from the right side of the heart through the pulmonary…

pulse flow (it can contract and stretch) The outer layer (tunica adventitia) contains collagen prevents the artery rupturing due to the high pressure blood flow Veins Veins carry blood under low pressure (<10 mm Hg) They have a very wide lumen (keeps pressure low and allows greater flow of blood) The walls of tissue surrounding the vein are thin (blood is not travelling in rhythmic pulses) They have valves to prevent blood pooling at extremities (arteries do not have valves) Capillaries…

Blood Pressure: Systolic and Diastolic Abstract Blood pressure is when your heart beats and so it pumps blood back up to your body for it to have energy and oxygen. However, as your blood pushes it creates strength, so this creates blood pressure. Pulse is to see the rate of your heart going beats per minute. In this experiment, we gather data to see if the level of physical activity could affect the result of the systolic and diastolic measures in blood pressure and if the pulse would also be…

The heart is comprised of four chambers, the right atrium, right ventricle, left atrium and the left ventricle. The right atrium is the chamber which receives blood from the body that has been depleted from its oxygen and pumps it to the right ventricle. The right ventricle then pumps the blood from the right atrium over to the pulmonary artery which as the name would suggest means it goes to the lungs and the oxygen depleted blood is once again oxygenated. The left atrium of the heart then…

Agriculture is a practice of farming where it grows crops and nurture animals to provide food, wool, and other good products. The agricultural production is the main source for developing countries currency where those countries need to buy necessary machines and equipment for manufacture of agriculture. One of the most important crops in Asia agriculture production is the “miracle and amazing” rice that has been expanding for generation. As today’s society, many other countries around the world…

of arteries, arterioles, capillaries venous and veins. (Sherwood). Understanding this fundamental system is critical to help further understand even more complicated medical conditions such as Postural orthostatic tachycardia syndrome (POTS), inappropriate HR increase when standing (Freeman et al., 2011). In addition, the cardiovascular system also has other properties that helps ensure proper function. One of those properties involves how the veins dilate in response to metabolites, waste…

1. Auscultation method is more accurate by using the stethoscope to listen for systolic blood pressure compared to palpation of systolic blood pressure at wrist. It is easier to listen for the ‘tap’ during the systolic pressure rather than palpating for it, as the systolic pressure may not be palpated if it is a weak pulse. 2. Systolic pressure: • Pressure in the arteries when the blood is being pumped out of the heart into the arteries • The maximum blood pressure, when the ventricles are in…

or reduce the coagulation of blood, prolonging the clotting time. Given a drug like Heparin acutely can limit the further formation of thrombus. When given chronically, for example Warfarin help prevent thromboembolism from the venous system (Leg veins). These drugs can also prevent clot formation in a dissected area. Thrombolytic drugs dissolve blood clots by activating plasminogen, which forms a cleaved product called plasmin. Plasmin is a proteolytic enzyme that is capable of breaking…

story questions then temperature, blood pressure, pulse and hemoglobin are checked to ensure donor’s blood is safe to use.), donating (where the donor is asked to sit on a chair. His or her blood is cleaned with alcohol and a needle is inserted into a vein in his or her arm. The needle is removed after fifteen minutes when nearly a pint of blood of blood has been collected.) and refreshment (where the donor spends a few minutes enjoying refreshments to replace the fluids that he or she lost…

Furthermore, the more we exercise changes would occur in our cardiovascular system. When performing exercise, your muscles would need sufficient amount of oxygen and nutrients so that you can perform well. Also, the carbon dioxide produced should be released from the body. It is the main role of the heart to pump harder and faster when exercising so that oxygen is taken in and carbon dioxide is released as a by-product. There are many acute changes that occur in this system before, during and…
