  • Aneurysms - 476 words
    Aneurysms By definition, an aneurysm is swelling of the blood vessel. They commonly occur in an artery or vein after a heart attack. An aneurysm can cause a blood clot, which can lead to major damage to the heart and brain. Identifying an aneurysm is very difficult. There are very little symptoms that can be detected. The symptoms change depending on where the artery is located:  A Thoracic aneurysm produces a dry cough; pain in the chest neck, back and abdomen.

  • Animal Experimentation - 1,936 words
    ... and adults. The only reason man is able to perform these vital operations is because dogs, who are the closest model to humans for this type of procedure at this time, were used for experimentation. By using the canines for experimentation, they have been able to perfect heart surgery in humans (Wil 65). Another benefit humans have had because of animal experimentation is the treatment of familial hypercholestolemia. It was discovered that Watanabe rabbits have a genetic disorder in which they have dangerously high cholesterol levels. A doctor found this problem on the rabbits' feet, which had yellow "pockets" full of liquid. He soon found out this disorder was similar to the ones in hu ...

  • Cardiac Pacemakers - 1,382 words
    Cardiac Pacemakers CARDIAC PACEMAKERS The heart is bestowed with a specialized system that automatically generates rhythmic control via the sinus node, located in the superior lateral wall of the right atrium near the opening of the superior vena cava. The specialized pacemaker cells dictate control of the rest of the heart through regular electrical impulses that propagate from the right atria to the lower ventricles. The rapid conduction of these impulses cause the muscle cells of the atria to contract and squeeze blood into the ventricles, which contract and force blood into the aorta and pulmonary arteries. Abnormalities of the heart rhythm, called arrhythmias, can disrupt this normal ca ...

  • Cocaine Abuse - 909 words
    Cocaine Abuse It is used in offices, parties, on street corners, in homes, and even in schools. With so much widespread abuse, cocaine is in extreme demand. Cocaine abuse has risen 118% since 1990, and continues to rise. Cocaine addiction is easy to understand-- it [cocaine] produces a good feeling, so naturally people would tend to want more of it. The question now though, is how does it produce these feelings, and why is the addiction so strong.

  • Diabetes - 3,161 words
    Diabetes Diabetes Diabetes, Diabetes Mellitus, is a chronic illness this means that it has no cure and the symptoms persist over a long period of time. This illness is a result of an imbalance of hormones, insulin, produced in the pancreas. Insulin plays an important role in how the body uses food. Insulin enables the cells in the bloodstream to absorb and use glucose for fuel. If the pancreas produces too little or no insulin or if the insulin doesnt work properly the person may become diabetic. Therefore, diabetics are not able to properly convert food into fuels needed by the body to function, which can seriously lead to physical consequences. The pancreas, located behind the stomach, is ...

  • Eating Disorders - 772 words
    Eating Disorders There are many different types of eating disorders in our world today and many suffer from them. Young women, and the reason is unknown, are the main targets.

There are two very common eating disorders: anorexia and bulimia. Anorexia nervosa is an eating disorder that is characterized by a person with a body weight less than 85% of what is considered normal weight. Anorexics have a fear of being fat.
