High Blood Pressure Is The Resistance Of Blood Vessels

Blood pressure is the force exerted by the blood against the walls of blood vessels, and the magnitude of this force depends on the cardiac output and the resistance of the blood vessels. When the systolic blood pressure (SBP) which is the pressure as the heart pumps blood around the body is 140 mm Hg or more, or a diastolic blood pressure (DBP) which is the pressure as the heart relaxes and refills with blood, is 90 mm Hg or more, and the individual is taking antihypertensive medication, it is called Hypertension (Madhur, 2014). High blood pressure is a major risk factor for various other illnesses and even death due to several cardiac and vascular diseases. It is assessed that about 54% of strokes, 47% of heart attacks, 75% of hypertensive disease, 25% of other heart disease, 13.5% of all mortality, and 6% of morbidity are linked to Hypertension (Khraim Pike, 2014). Hypertension affects about 70 million adults in the United States. Only about half (52%) of people with hypertensio n have their blood pressure under control. Nearly 1 in 3 American adults have prehypertension which means that blood pressure numbers are greater than usual, but not in the high blood pressure range. Hypertension costs the country about $46 billion annually. This comprises the cost of health care services, drugs to treat hypertension, and days of absence from work (CDC, 2015).

Essay1321 Words   |  6 Pagessystem apply concepts in physics as the blood circulates through the entire system? The circulatory system’s main objective is to transport blood throughout all the necessary parts of the body. The blood in effect transports nutrients and oxygen to these body parts and wastes away from these body parts to the organs that excrete them out of the body. The heart is the nerve centre of the circulatory system. This is so as it is this organ that pumps the blood that carries both the nutrients and wastesRead MoreBlood Pressure Regulation1269 Words   |  6 PagesBlood pressure regulation and changes occurring after increase in blood pressure Each time the heart pumps, it sends blood all over the body to supply organs and tissues with oxygen and nutrients. The strength of the force created as the heart pumps blood into the vessels together with the vessels’ resistance to the blood flow is defined as the body’s blood pressure (Darovic, 2002). A normal range blood pressure (BP) must be between 100-130mmHg systolic (when the heart is beating) and 60-90mmHgRead MoreWhat Is Pharmacology And It s Purpose?1482 Words   |  6 PagesAngina, which is sometimes called angina pectoris, is chest pain that is caused by inadequate coronary blood flow to the myocardium. When coronary blood flow cannot deliver sufficient oxygen to support cardiac oxidative metabolism (reduced oxygen), the myocardium becomes hypoxic. This triggers pain receptors within the heart, which lead to chest pain and the sensation of heaviness and pressure. One medication associated with angina is Ranexa, which is a category c drug. A drug may be classifiedRead MoreMedical Case Study1511 Words   |  7 Pagespresented in the ED with a history of chronic alcoholism, diabetes mellitis type 2, aortic valve stenosis and shortness of breath.

Poiseuille’s law was discovered by Jean Louis Marie Poiseuille in 1840 (Poiseu ille’s). Jean Louis used his experiments to find the smooth, laminar flow in circular tubing (Jean-Louis). His findings can be described as the flow of blood through the body and bronchial smooth muscle. When the resistance of a fluid increases, the flow will decrease. One exampleRead MoreMedication Of Blood Clot Formation1289 Words   |  6 PagesPart A They have been working. But aspirin helps to prevent blood clot formation and not elimination. Due to diabetes, insulin resistance in your body is high, excessive cholesterol and fat consumption will increase chances of heart diseases more. These factors lead to accumulation of blood clots and damaged arteries which increase blood pressure and decrease blood flow to your heart that is beyond what aspirin can regulate. 66 words You did not experience a heart attack as the test for CKMBRead MoreA Short Note On Diabetes And Adult Onset Diabetes1652 Words   |  7 Pagestakes glucose from your blood and moves it into the cells which fuels your cells, enabling them to function properly (mayo clinic, 2014). Contradictory to type 1 diabetes, the pancreas still functions and produces insulin with type 2 (Rosdahl Kowalski, 2012, p. [Page #1294]). The reason why the effectiveness of insulin is inhibited with type 2 diabetes is because of insulin resistance or the pancreas cannot produce the amount of insulin that the body demands. Insulin resistance is commonly caused byRead MoreThe Circulatory System Controls The Steady Circulation1273 Words   |  6 PagesThe circulatory system controls the steady circulation of the blood through the body by means of heart and blood vessels. It is intricately designed to get blood, oxygen, and nutrients to each and every cell through the human body. While bringing cells the nec essities to replenish themselves and multiply, the circulatory system also aids in the removal of waste and the return of deoxygenated blood back to the heart and lungs. This is done through the heart, lungs, arteries, veins, and capillariesRead MoreLab Assignment1565 Words   |  7 Pagesnourishment that are both received from the pumping of blood. Increased venous return causes the stroke volume to increase. 3. Discuss the importance of the change in CO with exercise? (1 point) The muscles are metabolizing much quicker to produce the mechanical energy required for exercise, meaning they need more oxygen. Blood is how the body delivers O2 to the tissues, hence your skeletal muscles need more blood. The way to get more blood to the tissues is to increase cardiac output. Application
