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…
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…
the blood reaches the capillaries…After passing through the capillaries, the blood returns to the heart by traveling through veins. Veins, which are small and numerous near the capillaries, form larger and larger vessels. At the same time, there are fewer and fewer of these larger vessels, so only a few large veins return blood directly to the heart.” (Shannon and Yunis 363) Sadly, however, even after Harvey announced these discoveries and released recordings of his research and evidence of…
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…
We all know that the main functions of the blood are the transport of respiratory gases, digested food or nutrients, waste products, hormones, enzymes and ions from one body part to another, it protects a body against diseases and regulates body temperature. In other words, blood is the essence of life. A body cannot survive without a sufficient amount of blood. Unfortunately, there are people who don’t have the same chances as we do. Let us take the United States as example. Every two…
The terms heart disease and cardiovascular disease are interchangeable. “Cardiovascular disease is caused by narrowed, blocked or stiffened blood vessels that prevent your heart, brain or other parts of your body from receiving enough blood”(“Diseases”). Heart disease kills by suffocating a body from the inside. Heart disease causes “36 percent” of deaths in America(“Top”). An abstract example of heart…
During my dialysis experience I found it to be very informative and interesting. We were not allowed to touch the patients or help with any care but the staff was interactive and explained was they were doing. The staff also was able to provided scenarios of different complications that happened and how they 'd respond. By the end of the first day I was able to see what the caregiver would due if a patient had muscle cramps, was short of breath and had chest pain. The first day I mostly…
nutrients, hormones and cellular waste products and permits blood to circulate and form cells in the body to nourish it with every heartbeat throughout the body.However, the Cardiovascular system is composed of the following organs, heart and blood vessels, including arteries, veins, and capillaries. One of the major structures of this system is the heart which functions to propel blood throughout the body, supplying oxygen and nutrients to the tissues. For example, the right side of the heart…
