It occurs when the flow of blood to the heart is blocked, there is a number of things that can cause this to occur’ (heart attack, 2017) Causes: • Bad cholesterol • High blood pressure ( this can damage arteries) • High intake of trans and saturated fats • Smoking • If family in the past have had history with heart attacks you may be at risk • Obesity • Stress • Illegal drug use (such as cocaine ) • Lack of physical activity • Age (men age 45+ and woman 55+ are more at risk of having a heart attack ) Symptoms: • Cold sweat • Fatigue • Tightness in the chest or arms • Struggling to breath • Dizziness Atherosclerosis Definition: This is also known as high cholesterol. It occurs when the blood flow from blood vessels become restricted, the vessels themselves become thick and stiff. Causes: • High cholesterol • High blood pressure • Inflammation from diseases such as arthritis • Obesity • Family history of high cholesterol • Lack of exercise • Unhealthy
Describe the 3 main types of blood circulation? - https://www.reference.com/science/three-types-circulation-28f4fb9363b09f33 The three types main types of blood circulation are 1 - Systemic circulation 2 – Pulmonary circulation 3 – Portal circulation These three systems work together for the proper oxygenation and blood flow throughout the body. Systemic Circulation is when the network of vessels carry blood from the heart to the body and from the body back to the heart Pulmonary Circulation is a network of vessels that carries blood to and from the lungs Portal Circulation is the network of arteries and veins that supplies blood to all the cells of the heart Describe the cardiac cycle and blood pressure Ref -
A study published in 2017 looked at the effects of BIPAP on Dyspnea and exercise tolerance in heart failure patients: Patient requirements included a NYHA classification of I, II, and III, having heart failure for six months or longer, and a left ventricular ejection fraction of less than 45%. Forty patients were split into two groups. One group was treated with BIPAP while the other was not. A six min walk study was done before and after the use of BIPAP. This study found that the use of BIPAP decreased the sense of Dyspnea, and increased the walking distance that the patients were able to do during the six min walk study.21 A study by Khayat et al.21 also showed that BIPAP could improve the function of both
Most of the blood flow across to the left atrium through the foramen ovale. Then blood moves down into the left ventricle. It is then pumped into the ascending aorta. From the aorta, the oxygen-rich blood is sent to the brain, to the heart muscle, and to the lower body. Blood returning to the heart from the fetal body contains carbon dioxide and waste products as it enters the right atrium.
The aged people are more prone to heart diseases including men. Examples of heart diseases include; heart failure, coronary artery diseases, congenital heart diseases etc. the causes of heart diseases include heredity, excessive smoking and weight gain, lack of rest, diabetes mellitus, sedentary lifestyle etc. To a greater extent, most heart diseases are preventable and the people at risk of having this disease include; heavy smokers, fat people, people that does not exercise and those that perform stressful activities, diabetic people, familial tendency etc. The nurse plays her roles in reducing and preventing
Perfusion : Perfusion is the process of a body delivering blood to a capillary bed in itsbiological tissue. The word is derived from the French verb "perfuser" meaning to "pour over or through". Tests verifying that adequate perfusion exists are a part of a patient's assessment process that are performed by medical or emergency personnel. The most common methods include evaluating a body's skin color, temperature, condition and capillary refill. Perfusionists employ artificial blood pumps to propel open-heart surgery patients' blood through their body tissue, replacing the function of the heart while the cardiac surgeon operates.
The heart forces the ‘oxygenated’ blood through a range of connecting blood vessels specifically speaking arteries which travel around your body providing your cells with the necessary materials that the blood contains. As the blood reaches your cells the oxygen is released in order for the cells to function. The cells then give out waste materials which can include co2 and water. In order for your blood to receive these waste products they absorb it. We now have deoxygenated blood which goes through your veins aiming towards your heart.
NATOMY AND PHYSIOLOGY In this assignment the author will describe the functions and structure of the main systems of the body and their interrelationship. 1. Explain the Function of the Heart and the structure of the Arteries, Capillaries and Veins: Function of the Heart: The heart is a muscular organ in humans which pumps blood through the bold vessels of the circulatory system. Blood provides the body with oxygen and nutrients and also assists in the removal of waste. The heart is a pump that drives the whole circulatory system.
Failure in one organ can cause other organs in the body to come under stress and restrict body functions. In the long run organ failures can endanger a patient’s life. Multiple organ failure occurs when two or more organs in the body fail. There are many reasons for organ failure and each organ has its own reasons as related to its function. Some common reasons for organ failure
Introduction The human respiratory system is a series of organs responsible for taking in oxygen and removing carbon dioxide, a waste product that if allowed to accumulate, can be lethal. The respiratory system works with the circulatory system in that the red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed. This project will take you through the functions and anatomy of the of the respiratory system, the mechanics of breathing, the disorders of the system and how massage or holistic approaches can be used to treat these diseases instead of traditional medical routes. Functions of the Respiratory System Through breathing, inhalation, and exhalation, the respiratory system facilitates
Transposition of the Great Arteries, Pediatric A good way to understand this condition is to first think about how blood flows in the body. Arteries are blood vessels that carry blood away from the heart to other places in the body. The two largest of these arteries are called the great arteries. One of them, the pulmonary artery, takes blood from the heart to the lungs. In the lungs, oxygen is added to the blood.
The heart is a muscular organ the size of a clenched fist situated in the middle of the chest tilted slightly to the left. The heart receives its own oxygenated blood supplied by the coronary arteries and the coronary veins that take away the deoxygenated blood. The heart is made up of four chambers the left and right atrium and the left and right ventricle. The oxygenated blood travels from the lungs through the pulmonary veins, the pulmonary vein are the only veins in the body that carry oxygenated blood to the heart, the blood then enters the left atrium the blood is then pushed through the bicuspid valve, where the blood now enters the left ventricle where the blood is then pumped through the aortic valve into the aorta where the oxygenated
Right-sided heart failure is when the cardiac muscle on the right side of the heart becomes too weak to pump a sufficient amount of deoxygenated blood to the lungs. It is usually a complication of various conditions including lung diseases such as emphysema. This means that less oxygenated blood is taken from the lungs by the pulmonary veins and transported to the left side of the heart to then be pumped around the body. It can also produce a back-up of blood in the vessels within the body. This failure to pump sufficient blood to the lungs results in a build-up of fluid, which is known as oedema.
Heart Valve disease is when you heart valves dont work the way they should. This is part of the cardiovascular system. Your heart valves lie at the exit of each of your four heart chambers and maintain one-way blood flow through your heart. The four heart valves make sure that blood always flows freely in a forward direction and that there is no backward leakage. Blood flows from your right and left atria into your ventricles through the open tricuspid and mitral valves.
