Result of a Cerebrovascular Accident (CVA) of the middle cerebral artery which supplies Brodmann areas 312 and 4 in the left cerebral hemisphere A cerebrovascular accident is also known as a stroke. It is when the blood which flows to the brain is cut off, by a blocked or ruptured artery that goes to the brain, causing the brain not to receive enough oxygen and cells of the brain then die11. ?????? result of CVA on middle cerebral artery 3.2.2 Difference between a haemorrhagic and an ischaemic…

This buildup restricts blood flow and can block it altogether. Your heart must work harder to push blood through narrowed arteries which increases your blood pressure. This artery narrowing is often the result of eating fatty foods and those high in cholesterol. Diet isn 't the only life choice that impacts heart health. Other behaviors that put you at risk for heart disease include smoking tobacco…

factors. The heart is responsible for pumping blood throughout the body. The arteries take the blood away from the heart and the veins bring it back to it, completing the circuit. This process is what brings oxygen, nutrients, and protection to the body 's cells. It is also the process that takes waste materials from the cells to be removed from the body. If the cardiovascular (cardio – heart, vascular – veins and arteries) system does not work properly, the body cannot function. The main…

Blood pressure is measure of blood flow forcing against the walls of the arteries. Hypertension is a medical condition when the systolic blood pressure measures more than 140mmHg and diastolic measures more than 90mmHg. The World Health Organisation considers hypertension as a serious epidemic. According to the last estimate by WHO, 40% of the adults aged 25 and above had been diagnosed with hypertension. In 1980, 600 million people around the world had Hypertension, by 2008, there were 1…

Atherosclerosis is the process of plaque formation within medium to large arteries. The actual cause of the pathology is unknown; however, there are many risk factors that contribute to atherosclerosis including: cigarette smoking, hypertension, hyperlipidemia, diabetes…

Hyperlipidemia can be caused by a high fat diet. The fat accumulates on the arteries. This can narrow the arteries, which makes it more difficult for blood to pass through. This causes hypertension. The heart has to work harder to pump the blood through the narrowed arteries. If the coronary arteries become narrowed coronary artery disease occurs. The coronary arteries supply the heart muscle with blood. When blood is restricted to the heart chronic heart failure can…

in one eye. The loss of vision in the affected eye may be total or partial. It usually lasts just a few seconds or minutes. Then, it returns to normal. Occasionally, it may last for several hours. This is caused by interruption of blood flow to the artery that supplies blood to the retina (lining at the back of the eye, contains nerves needed for sight). The temporary loss of blood flow causes symptoms similar to a stroke. The family of symptoms that happen from a loss of blood flow is called a…

organs; maintaining homeostasis; and transport gases, waste, and hormones. The different types of blood vessels are: arteries, capillaries, and veins. The vessels that carry blood towards the heart are veins and the vessels that carry blood away from the heart are arteries. Gas exchange occurs in the capillaries. 2. Describe the layers of blood vessels. Describe the differences between arteries and veins. The layers of blood vessels are: a hollow interior (lumen), contains an outer…

Description Angiography is a medical imaging technique used to visualize the inside of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. It is used to detect abnormalities, including narrowing (stenosis) or blockages in the blood vessels (called occlusions) throughout the circulatory system and in some organs. It is the x-ray (radiographic) study of the blood vessels. Pre Surgery Your doctor may recommend coronary angiography if you…
