Coronary circulation

Many people do not help stop the major international conflict. Part of this conflict starts with ignorance. “In 2005, to date the hottest year on record, there was a massive loss of coral reefs, including some that were healthy and thriving when Columbus first arrived in the Caribbean. In 1998, the second hottest year on record, the world lost an estimate of 16 percent of all its coral reefs” (Gore 164). This quote states the increasing of pollution in the atmosphere and the pollution is…

Ice Age however, there is also the possibility of the early onset of the next Ice Age. in the article “crippled Atlantic currents triggered ice age climate change” it is discussed how in the last glacial period the Atlantic Meridional Overturning Circulation had begun to slow down right before periods of sudden climate change (Hand, 2016). As well today there is evidence of the AMOC currently “known to be in decline”. (Hand, 2016) This delay or early onset of the next ice age is human made,…

One of the main abiotic factors influencing the distribution of biomes is global atmospheric circulation. Global atmospheric circulation is the mass movement of air around earth caused by thermal energy. This mass movement of air causes three distinct atmospheric circulation cells to form, these are the Hadley Cell, Ferrel Cell and Polar Cell. Between these three cells is a dynamic area called the Intertropical Convergence Zone. Persson (2006) tells us that the Hadley Cell is caused by solar…

What Global Warming Will Bring Since the Big Bang, there have been a total of seven Ice ages and seven warm periods in the Earth’s history. Accordingly, when the climate changes, many conditions such as sea levels, temperature, humidity and even the major existence of species have been altered as a natural phenomenon. As for this era, we are in interglacial period. Interglacial period is a period that exists between each Ice age, and its climate is altered so slowly that animals cannot even…

A pressing issue in Pakistan is the country’s vulnerability to climate change. In 2011 the Global Climate Change Vulnerability Index ranked Pakistan as the 16th most vulnerable country after enduring many severe floods, droughts and storms. In a country that relies heavily on the agriculture sector, taking up 45% of employment, the effect of climate change on farming is a serious matter that creates a possible threat to everyday lifestyle. While this issue has created discussion within the…

Atmospheric Global Circulation is the movement of air caused by solar energy and the interaction of warm and cold air - this convergence forms cells or belts over the Earth’s surface. George Hadley (1685–1768) a British physicist and meteorologist, who first described this theory in 1753, did so using what is known as the Single-Cell Atmospheric Global Circulation Model or Hadley Cell (The Editors of Encyclopædia Britannica, 2007). Hadley’s Single-Cell theory failed to consider the Coriolis…

After reading and discussing “Learning to Die in the Anthropocene” I was left class thinking about it a lot. I really enjoyed the reading, but sort of left with the feeling that it was useless. While it clearly did not offer any practical solutions for climate change, I believe it offered an insight that can be incredibly powerful. Science can tell us climate change is a problem and that x, y, and z will happen if we do not stop doing what we are doing. For the most part, we know this. It is,…

45% of deaths due to coronary heart disease. “Types and Conditions of CVD. The term cardio-vascular disease (CVD) encompasses a wide spectrum of disease, which include Ischaemic Heart Disease (IHD), heart diseses other than IHD, systemic arterial hypertension, stroke, and peripheral vascular disease (PVD). IHD is the prototype example of lifestyle disease; it is defined as a stake of lack of supply of oxygen to the myocardium vis-a-vis the demand due to narrowing of the coronary arteries as a…

of total death per year. Cardiovascular disease is the disease of heart and vascular system of the human body that includes narrowing down or blocking of blood vessels (arteries, veins and capillaries) that can lead to range of diseases such as coronary artery disease, arrhythmia, congenital heart defects, angina (chest pain) and stroke. Even though cardiovascular disease is common only in adult population, it is very likely that each age group including children and adolescents have the…

thinning of the peripheral arteries of the stomach, head, arms and legs. Not to mention, PAD is comparable to Coronary artery disease (CAD) and symptoms include pain or cramping in the lower extremities, tiredness in the legs or muscles of the hip and thinning of skin on the legs (Pescatello, 2014). This disease refers to a number of disorders in which the flow of blood through the non-coronary arterial beds are impaired. This type of condition commonly affects the tibial, renal, femoral, iliac…
