Introduction The cardiovascular system is a fundamental system for survival, providing the body nutrients and removing waste via a network of arteries, arterioles, capillaries venous and veins. (Sherwood). Understanding this fundamental system is critical to help further understand even more complicated medical conditions such as Postural orthostatic tachycardia syndrome (POTS), inappropriate HR increase when standing (Freeman et al., 2011). In addition, the cardiovascular system also has…

Introduction: The heart is part of the circulatory system which pumps blood and supplies oxygen throughout our body(Jacobs). Pumped through a network of arteries and veins, blood is a very important part of our body. Without blood, we could not live. This is because it keeps us warm, fights off infections, and helps get rid of waste(Durani). Blood also transports oxygen and hormones throughout our body. Our circulatory system is made up of the heart and blood vessels. They also include…

“Welcome To –“read a sign that was found standing in front of a pathway leading into a lively town. Of course the sign advertised the name of the town but the old man didn’t seem to care to read it. He was a wanderer, he wandered endlessly with no destination because he didn’t have one; he didn’t have anything. He was old and had gray hair. His face was withered and his eyes were cold; almost mechanical. All of life’s hardships had taken its toll on him and it showed, for every wrinkle, there…

Que: 1 Describes the components and conduction pathway of the cardiac conduction system of the heart.relate the cardiac condution system to the corresponding sequence of heart chamber contractions. The cardiac conduction system refers to a group of specialized muscle cells of the heart’s wall (Assadi, 2013). The cells are meant to send signals to the cardiac muscles thus contraction. The major components of the cardiac conduction system are the Atrioventricular node, sinuatrial node, the bundle…

system, principally cardiac disease, vascular diseases of the brain and kidney, and peripheral arterial disease. The causes of cardiovascular disease are diverse but atherosclerosis and/or hypertension are the most common. In addition, with aging come a number of physiological and morphological changes that alter cardiovascular function and lead to increased risk of cardiovascular disease, even in healthy asymptomatic individuals. Heart attacks and strokes are usually acute events and are mainly…

Leonardo da Vinci was intellectually well-rounded and produced masterpieces of art, scientific investigation, and architecture throughout his long life. “Learning never exhausts the mind.” These are some of the wise words of Leonardo da Vinci. This particular quote personally stands out to me because da Vinci never let up on learning until the day he died, he just always kept it up. This love of learning, consequently, cultivated his fascination and close studies of the human anatomy. Da Vinci…

disease. In 70% of the cases, testing the mother’s ATP7A gene for the mutation can also make the diagnoses. Performing an ultrasound on the bladder can show diverticula which is also an indication of the disorder. In severe cases, thickening of the aortic valve may occur.…

Background Progeria is an extremely rare form of dwarfism, affecting a mere 200-250 children worldwide at a time (Gordon, 2013).Classically known as Hutchinson-Gilford progeria syndrome, HGPS is a disease that causes the body to "prematurely age". Manifestations of this disease affects the skin, musculoskeletal system, and vasculature. The term progeria is derived from the Greek word geras, meaning "old age" (Shah, 2015). Dr. Jonathan Hutchinson first described this syndrome in 1886, and…

condition leaves her heart greatly affected and she has been on medication since she was one year old. She requires echocardiograms at least three times a year to monitor the growth of her aorta and other valves. Layne will eventually have to have heart surgery to preventively replace her aortic valve. Layne also suffers from severe scoliosis and is considered to be legally blind because of her low vision. Due to her severe scoliosis, her back was curved immensely. Layne has had to have surgery…

enters the aorta; this causes the stretching of the left ventricle and acts as functioning part of the ventricle (IBID). While the diastolic pressure is the flow of blood from the aorta into the smallest vessels as the aortic valve closes and recoils back. This occurs when the aortic valve is at its lowest and causes resistance of blood vessels (Marieb & Hoehn, 2010). Measuring and interpreting correctly patient’s vital signs is one of the skills requirement for pre-registration that a student…
