The Heart

The heart is one of the most vital organs in the body. It has many different functions and parts. One of the important parts of the heart is the pericardium. The pericardium is the fluid filled sac that surrounds the heart and the proximal ends of the aorta, vena cava, and the pulmonary artery. There are about three functions of the pericardium. First, it keeps the heart contained in the chest cavity, second, it prevents the heart from over-expanding when blood volume increases, and third, limits heart motion. The pericardium is divided into about three layers. The first layer is the Fibrous Pericardium. “The Fibrous Pericardium is the outer fibrous sac that covers the heart.”# It provides an outer protective layer for the heart, keeps the heart contained in the chest cavity, and Prevents the heart from over-expanding when blood volume increases. The second layer of the pericardium is the viseral pericardium also known as the epicardium. “The viseral pericardium or the epicardium is the outer layer of the wall of the heart.”# It is composed of connective tissue covered by epithelium. It provides an extra outer layer for the heart. “The third layer of the Pericardium is known as the parietal pericardium. The


Another important part of the heart are the alveoli. They are the final branches of the respiratory tree and act as the primary gas exchange units of the lung. The gas-blood barrier between the alveolar space and the pulmonary capillaries is extremely thin, allowing for rapid gas exchange. To reach the blood, oxygen must diffuse through the alveolar epithelium, a thin space between the capillary endothelium. The opposite follows the reverse course to reach the alveoli.

The way you can prevent some of these heart disease is by having less stress in your life, by not smoking, and by obtaining low cholesterol. There are several ways to obtain less stress in your life. “There is ‘good’ stress, which everyone needs to function properly on both an emotional and physical level. But there is also ‘bad’ stress, or distress, which can be triggered whenever life’s demands exceed your perceived ability to cope with them. The Stress Less approach to reducing stress is a multidisciplinary one aimed at helping you understand your stress response, recognize the stressors in your life and incorporate useful stress reduction strategies.”# Some helpful “hints” to reduce stress can be books, videos, special events, special products, or special exercises that focus on stress reduction. Having less stress in your life can and will help prevent some heart diseases.

Another disease or malfunction of the heart is, congestive heart failure (CHF), or heart failure, which is a condition in which the heart cannot pump enough blood to the bodies other organs. This can result from several things such as: Narrowed arteries, past heart attack, high blood pressure, heart valve disease, primary disease of the heart muscle itself, heart defects present at birth, or infection of the heart valves and/or heart muscle itself.
