With age the function of the heart is influenced mainly by the decrease in the elasticity and the ability to respond to changes in pressure of the artery system. Therefore the increase in the resistance to the pumping action of the heart increases the work needed to drive the blood to the various organs of the body. Older people have an increased risk of getting Cardio vascular disease and are increasingly common with advancing age. As a person gets older, the heart undergoes physiologic changes

a human heart. Each structure of the heart has a different function and a different location. The hearts size is the about the size of a human fist. It takes in deoxygenated blood through the veins and brings it to the lungs to get oxygenated and then pumps it into the various arteries. The heart is in a fluid filled cavity called the pericardial cavity. The walls and the lining of the heart are membranes which are called pericardium. Its function is to lubricate the heart and to prevent

emotional and relational overload can negatively affect the ability to hear, see, and speak (23-30). Within the Flat-Brain Theory the stomach begins to expand because it becomes overloaded with different emotions. These emotions then press the heart functions into bricks in the chest, which negatively hinders the ability to relate. This then affects the brain causing it to flatten. The brain becomes pressed against the skull resulting in our thinking, hearing, and seeing to be off. Therefore

Cardiovascular system It consists of the heart and blood vessels (arteries and veins). The heart It is a muscle that functions as an extremely powerful pump to drive blood through the arteries and suck the blood from the veins come. The size of the fist, weighs about 300 grams and pump 5 liters of blood per minute. The heart represents only 0.4% of total body weight but consumes 10% of the oxygen provided by breathing. Arteries These are the vessels that carry blood from the heart to all organs. The transported

PCI procedures is that patients undergoing CABG must be placed on a heart-lung machine. Major vessels going in and out of the heart (vena cava, aorta) are clamped off, and blood flow is diverted to the heart lung machine. The heart lung machine temporarily takes over oxygenation and blood circulation duties, while the heart is stopped (induced cardiac arrest) so that the surgeons may perform the grafting procedure. The use of a heart-lung machine and induced cardiac arrest are major interventions that

is necessary. There are two different arterial systems in the human body: the Pulmonary artery system and the Systemic artery system. The pulmonary arteries carry blood away from the heart toward the lungs where blood becomes oxygenated and the systemic arteries oppositely carry oxygenated blood away from the heart and into the body’s tissues and organs. The anatomy of an artery can be viewed through three layers: the tunica externa, media, and intima. The tunica externa is the outermost layer
