Coronary Heart Disease Heart diseases are one of the most killing diseases in the United States‚ where there are more than half a million people die of a hteart the disease every year. That is a 1 in every 4 deaths‚ which is a very huge number. (wc) About 370 thousands of these people die of the most killing type which is the coronary heart disease. (1) Since the coronary heart disease is very common nowadays‚ people should be educated on what exactly it is and how it happens‚ its risk

Question Sheet B Sharon Jackson 1. The septum separates the heart into a right and left side. If there was a hole in the septum there would be a mix of oxygen right blood and oxygen poor blood and some oxygen right blood can enter the lungs instead of the body. 2. Capillaries exchange materials with the cells of the body there veins return blood to the heart and arteries take blood away from the heart 3. The SA node‚ or sinoatrial node initiates the heartbeat and automatically sends out a signal

Interest Rate Risk (IRR) Management What is Interest Rate Risk : Interest rate risk is the risk where changes in market interest rates might adversely affect a bank’s financial condition. The management of Interest Rate Risk should be one of the critical components of market risk management in banks. The regulatory restrictions in the past had greatly reduced many of the risks in the banking system. Deregulation of interest rates has‚ however‚ exposed them to the adverse impacts of interest rate risk

The Rate of a Reaction The area of chemistry that deals with the rate or speed of chemical reactions is known a chemical kinetics. The word “kinetic” is derived from the Greek name kinitikos that means movement or motion. In the present context‚ the kinetic means the reaction rate or rate of a reaction that is defined as the change in concentration of a reactant or a product with time (M/s). Chemical reaction can be represented by the following general equation. Reactants Products It is very important

The body system that most interests me is the cardiovascular system‚ I chose this system because I’m fascinated with how the heart works and how the blood flows throughout our whole body. The heart is a muscle that contracts which allows blood to be pushed throughout the body. The heart provides many nutrients and blood to the whole body along with many vital organs. The heart is spilt into four chambers: the right atrium‚ left atrium‚ left ventricle‚ and right ventricle. The blood flow starts in the

4.0 Aetiology Scientists continue to research into the causes of coronary heart disease however‚ their has been limited new research into the aetiology. Therefore‚ the causes of atherosclerosis will be discussed as well as other diseases leading to coronary heart disease such as transient ischemia‚ coronary stenoses and lifestyle factors. 4.1 Atherosclerosis Coronary heart disease is commonly caused by a buildup of plaque which narrows the arteries and reduces blood flow causing platelets‚

Heart Dissection Practical Report. Introduction On the of July 2002‚ a sheep’s heart was examined by dissection. The heart is a muscle in all mammalian bodies that is used to pump blood and nutrients throughout the body. A sheep’s heart was used in this prac because like the human heart it has four chambers and is similar in size. Two of these chambers are receiving chambers called the left and right atrium. The other two are pumping chambers called the right and left ventricle. The reliability
