During exercise your body must adapt to the added stress and pressure you are putting onto it. The heart plays a very important role in maintaining homeostasis during exercise. When exercising your heart rate increases and the “Left Heart” have to pump out more oxygenated blood to the entire body. The sympathetic nervous system also plays an important role during exercise. The sympathetic pathway comes out of the lower cervical and upper thoracic segments of the spinal cord. The sympathetic

Coronary Heart Disease Coronary heart disease‚ also called coronary artery disease or ischemic heart disease‚ it characterized by an inadequate supply of oxygen-rich blood to the heart muscle (myocardium) because of narrowing or blocking of a coronary artery by fatty plaques. If the oxygen depletion is extreme‚ the effect may be a myocardial infarction (heart attack); if the deprivation is insufficient to cause infarction (death of a section of heart muscle)‚ the effect may be angina pectoris

Heart Diseases in the Philippines Mortality and morbidity The data we gathered shows that the average morbidity level during 2000-2004 almost did not change in 2005. However‚ the level of mortality is alarmingly increasing. This means that more people die from heart diseases than before. Since we are comparing average of 5 years with another succeeding year‚ we expected that the data won’t have significant differences just like in our data about mortality. This means that if we see big difference

Homeostasis of BP and Heart Rate A normal blood pressure can be identified by having a systolic pressure of around 120 and a diastolic pressure of around 80. This value is expressed as "120/80". A normal heart rate is expressed as the amount of times it beats in a minute; a normal adult heart rate is between 60-100 beats per minute (BPM). There is a relation between these two measurements‚ but they are stimulated by several different circumstances. The blood pressure is mainly affected

Coronary heart disease is a common term for the buildup of plaque in the heart’s arteries that could lead to heart attack. But what about coronary artery disease? Is there a difference? The short answer is often no — health professionals frequently use the terms interchangeably. However‚ coronary heart disease ‚ or CHD‚ is actually a result of coronary artery disease‚ or CAD‚ said Edward Fisher‚ M.D.‚ Ph.D.‚ an American Heart Association volunteer who is the Leon H. Charney Professor of Cardiovascular

The Heart and Circulation of Blood In this research paper‚ I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic circuit‚ as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used

carries oxygenated blood away from the heart. It supplies the brain‚ right arm‚ and neck with blood. Common carotid artery: The common carotid artery supplies oxygenated blood to the front of the brain as well as the head‚ neck‚ face‚ and spinal cord. Subclavian artery: The subclavian artery carries blood away from the heart and supplies oxygenated blood to the arms. Left pulmonary vein: The left pulmonary vein carries oxygenated blood from the left lung to the heart. Right pulmonary vein: The right

A congenital heart defect (CHD) is an abnormality in the structure or function of the heart. This can include circumstances that affect the walls of the organ‚ blood vessels that transport blood to and from it‚ and the valves that regulate blood flow. Some CHDs are minor‚ and cause no noticeable symptoms. Others are severe‚ and can place the patient’s life at risk. Symptoms vary according to the type of defect suffered‚ as well as its severity. In this article‚ we’ll explore a few of the most common

spread to the lining of the heart‚ which causes pericarditis. The infection can be caused by wounds that are left untreated or a weak immune system that just can’t fight off simple ailments‚ but it is most commonly caused by teeth problems‚ such as rotten teeth or gingivitis. The bacteria in the mouth quickly spreads to the blood system when a person eats food. And when it gets to the blood system‚ it is carried to the heart. This in turn makes the lining of the heart inflamed. If this condition
