Blood vessel pressure essay
This pressure is useful because it can be used to assess the condition of the heart, the amount of blood squeezed out of the heart upon contraction, the condition of the arteries and to some extent the viscosity and volume of the blood Kier, Wise and Krebs, 2003. An individual's blood pressure is measured in the brachial artery of the arm at the level of the arm. The general term 'blood pressure' usually refers to the mean arterial pressure MAP, which is an average of the systolic and diastolic pressures. The time in each phase is taken into account and MAP is worked out according to the formula: MAP, diastolic pressure, 0.33 systolic-diastolic. Meaney and colleagues 2000 have more. It is important to emphasize that the prevalence of hypertension with a systolic blood pressure of ≥, in patients with more advanced renal failure GFR lt, minus 1.73. High blood pressure can narrow and damage the arteries that supply blood to the heart. This damage is known as coronary artery disease. Too little blood flow to the heart can lead to chest pain called angina. It can lead to irregular heart rhythms called arrhythmias. Or it can lead to a heart attack. Angiogenesis is typically initiated from the capillaries and plays an important role in tumor growth, maintenance, and metastasis. Blood vessel formation in tumors can be induced by several cellular processes (Fig. 1), as briefly summarized below. Fig. 1. Mechanisms of blood vessel formation.1. Introduction. Cardiovascular disease is a group of diseases of the heart and blood vessels, including coronary heart disease, cerebrovascular disease, peripheral arterial disease, rheumatic heart disease, congenital heart disease and deep venous thrombosis. In recent years, cardiovascular disease has overtaken cancer as the leading cause of diabetes,
