it as well as many risk factors; nevertheless, with positive behavioral changes many of these risk factors can be reduced, thus creating physiological changes. The cardiovascular system is a complex system made up of the heart and the many blood vessels throughout the body. It is an essential system for stability and maintaining homeostasis, supplying every region of the body with just the right amount of blood…

Year 10 Biology IA Research Question How does consistent running up and down on the stairs at differing intensities affect the heart rate in Year 10 students? Introduction The main role of the circulatory system is the delivery of oxygen and nutrients and the removal of carbon dioxide and wastes. The circulatory system consists of the heart and the network of arteries, veins and capillaries. Carbon dioxide present in the body is carried by blood to the lungs for exhalation and oxygen is then…

a large effect on all systems of the body. W.R, a 48 year old plumber has a 36- pack year smoking history. One of the major effects of smoking is atherosclerosis. Atherosclerosis is the hardening and narrowing of the blood vessels due to a fat and plaque buildup on the vessels. Some of the major risk factors for atherosclerosis include hypercholesterolemia, increasing age, sex- male being more prevalent than females, high blood cholesterol levels, cigarette smoking, obesity, and hypertension,…

Agriculture is a practice of farming where it grows crops and nurture animals to provide food, wool, and other good products. The agricultural production is the main source for developing countries currency where those countries need to buy necessary machines and equipment for manufacture of agriculture. One of the most important crops in Asia agriculture production is the “miracle and amazing” rice that has been expanding for generation. As today’s society, many other countries around the world…

cardiovascular diseases. However, advance aging unequivocally confers the major risks. Cardiovascular disease refers to a range of diseases that affect the heart and the blood vessels. Among the common ones are heart attacks – blockage of the blood flow to a part of the heart, and ischemic stroke –blockage of a blood vessel that feeds a part of the brain. Other types of cardiovascular disease include heart failure, arrhythmia and heart valves problems. This paper…

Peripheral vascular disease is condition that applies when the arteries in the human body narrow, often away from the major heart or brain organs. When this occurs in these two vital organs, these conditions are known each as coronary artery disease and cerebrovascular disease, respectively. Peripheral vascular disease is often found to affect the legs. The common symptoms for this disease include pain along the leg while walking and even when found at rest. In the affected leg, the nails and…

An Arteriovenous Malformation (AVM) can be described simply as a tight rubber band ball of abnormal blood vessels with weak walls. These can be located anywhere in the body. Arteries carry blood containing oxygen from the heart to the brain. An AVM bypasses normal brain tissue and directs blood from the arteries to the veins without a capillary bed in between. Brain AVM’s occur in less than one percent of the population (per 100,000 people) and are more common in males than females. Being…

arteries. The arteries supply oxygen and rich blood to your heart muscle. When plaque builds up in the arteries, the condition is atherosclerosis and the buildup occurs over many years. Coronary heart disease is also a narrowing of the small blood vessels. Coronary artery disease can’t be cured, but treatment may help the disease. Coronary heart disease is the prime cause of death in the United States for men and women. In this essay I will tell you the causes, symptoms and the treatment of the…

Discovered in 1913 by a man named Nikolai Anichkov, atherosclerosis is a disease where things like calcium and fat build up in the arteries and block blood flow. Arteries harden as a result of it, and it’ll cause problems transferring blood around the body. The plaque will form a barrier, and can cause serious problems in the body, like other diseases and disorders. The results are possibly deadly. There is a layer on the inside of every vein that keeps it smooth called endothelium. It allows…
