Pulmonary vein

Mr. P is a 76-year-old male who admitted for congestive heart failure (CHF), and cardiomyopathy. Mr. P is despondent and a poor historian regarding his health. The patient does not demonstrate any concern to improve his current acute health issues. The patient presents with 4+ pitting edema, moist crackles throughout lung fields, and labored breathing. Mr. P’s wife has stated that he does not adhere to any diet restrictions and cannot keep track of medications. Mrs. P is distressed over her…

1. Coronary perfusion is a crucial factor in meeting cellular oxygen demands, which of the following factor can cause the decline in coronary perfusion? a) Heart Rate b) Contractility c) High blood pressure d) Platelet aggregation and thrombosis Answer: D Answer Rationale: A. (Incorrect) Heart rate and coronary perfusion is not correlated. An increase or decrease in heart rate along does not necessarily impact the coronary perfusion. In most cases, it is the vasodilation and vasoconstriction…

TITLE: Afterload reduction and beneficial in the management of heart failure Jose R Tapanes International Institute for Health Care Professionals Abstract Afterload is the pressure in the wall of the left ventricle during ejection. In other words, it is the end load against which the heart contracts to eject blood. Afterload is divided into components: one factor is the aortic pressure the left ventricular muscle must overcome to eject blood. There is an inverse relationship between afterload…

Task 2 Part A Cebita Santhosh Q1. The three main types of blood vessels in the circulatory system are veins, arteries and capillaries. The veins carry deoxygenated blood from the capillaries back to the heart. The arteries carry blood away from the heart to your tissues. The capillaries are the smallest of the body's blood vessels, only one cell thick and are found in the muscles and lungs. Q2. Eating too much salt can raise your blood pressure because of the extra water stored in the…

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…

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 receives the blood that has been oxygenated to the left ventricle. Finally the blood…

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…
