External carotid artery

often take a nitroglycerin tablet to relieve their symptoms. How does this relieve their symptoms? In your answer discuss (briefly) oxygen delivery to the heart. (3 points) Chronic angina can occur when there is a blockage or restriction in the arteries of the heart causing pain because of the lack of oxygenated blood flowing to the heart. The pain associated with chronic angina can become worse during exercise, when the heart is working harder, and better during rest, when the body requires…

Hemorrhagic stroke is broken in to two types, and the most common is the intracerebral hemorrhage, when an artery in the brain bursts flooding the brain with blood. The second and less common subarachnoid hemorrhage, when bleeding occurs in the area between the brain and the thin tissue that covers it. An ischemic stroke and a transient ischemic attack are both caused by a blockage in the artery that supplies oxygen rich blood to the brain, these are the most common types of stroke. With a…

explain and describe the process of the two stages in ischemic cardiomyopathy. The first stage for ischemic cardiomyopathy is a heart attack. During a heart attack, there are many actions happened to the body. Heart attack starts in a coronary artery or one of its smaller branches. It happens because the heart fails to get enough oxygen because of plaque. First, plaque builds up on the years from cholesterol, fat, and other nutrition. According to WebMD, ” The plaque…

Pericarditis A. Etiology – The most common causes of pericarditis are either that it is idiopathic (unknown origin), or due to a viral infection. Other causes include: trauma, a myocardial, infarction, other types of infection, or other inflammatory conditions. B. Pathophysiology – This pathology is the inflammation of the pericardium of the heart. This inflammation causes narrowing of the pericardial space, which may also cause scarring. If left untreated this may lead to pericardial effusion,…

The force of blood as it circulates against the blood vessel's inner walls is called blood pressure. There are many things affect blood pressure, causing it to rise. * The amount of force with which the blood pumps * The amount of blood in the body * The blood vessel's diameter So that generally, blood pressure rises when the heart pumps harder, there is an increase in the amount of blood in the body, or there is a decrease in the diameter of the blood vessels that carries the blood.…

Life or Death? A fourteen year old boy was undergoing surgery when his heart suddenly stopped. Otherwise known as cardiac arrest. Cardiac arrest is when the heart stops all electrical activity, eventually stopping the heart muscle from contracting. When the heart stops beating, the whole body including the brain does not receive oxygen. If the brain lacks oxygen for, ten to fifteen minutes, there could be permanent brain damage. It is crucial that the heart starts beating or someone starts…

In the United States, there are usually between 100,000 and 200,000 Anterior Cruciate Ligament (ACL) ruptures per year. (Osborne. M, 2012) (Why do females injure their knees four to six times more than men…and what can you do about it?) (ucdenver.edu) An ACL injury is the most common injury in female athletes. Female athletes are more prone to having an ACL injury because of the lack of muscle strength and control of their (Chang. W, 2014; Joseph et al., 2014). This injury can lead to…

Cardiac Differentiation Using BMP4 and CHIR99021 Cardiovascular diseases are the leading cause of death worldwide with approximately 600,000 deaths in the U.S. only. One of the major difficulties with heart diseases is the heart’s failure to produce new and healthy cells in a timely manner. Unfortunately, the heart lacks the ability to quickly generate new tissue composed of viable cells, leading to patient death. Cardiovascular progenitor cells (CVPCs) are believed to be highly useful in…

hypertension affect a community? Before I go further, let me first define hypertension, how it’s occur and what is the long time effect of hypertension. Hypertension which we also call high blood pressure is a condition in which the force of the blood in the artery reached higher than normal. As the years have gone by, it has been found that lower and lower blood pressure are better for preventing some complications of high blood pressure. In kidney disease this is particularly true. Really low…

Chronic cardiac failure can be defined as ‘a clinical syndrome that develops in response to a cardiac injury or insult that causes decline in the pumping capacity (contractile function) of the heart’ (Lymperopolous et al. 2013). Betty has been experiencing chest pain, a decreased appetite and shortness of breath indicated by her oxygen saturation levels and increased respiratory rate. Additionally, she has bilateral peripheral pitting oedema and has had a cough. These are all signs and symptoms…
