pressure. The blood pressure is the amount of blood the heart pumps and the resistance of blood flow in the arteries. If the heart pumps more blood than needed, or the arteries become narrower the result will be a higher blood pressure (3). The main purpose for treating hypertension is to decrease the risk of further complications that can lead to a stroke, and to prevent further narrowing of the arteries (8). M.B. (55), was admitted to the ICU three days ago with a hypertensive emergency (“a…

lungs. The network of blood vessels that branch over the surface of the heart are the coronary arteries. Figure 1 outlines the coronary arteries on the heart which supply the cardiac muscles with nutrients such as oxygen and glucose needed to survive [1]. Like any organ in the human body, the heart needs a constant supply of blood. Over time, fatty deposits can build up and form an atheroma on the artery lining. An atheroma is a hardened plaque caused by accumulated fatty deposits and scar…

the heart’s left and right atria and a plastic model is placed into chest inorder to determine the proper placement for the artificial heart.A special type of synthetic tissue is then cut up by suregons and sewn to the atora (artery to the body) and the pulmonary artery (artery to the lungs) This synthetic is used to help connect the artificial heart to the remaning parts the natural heart. The artificial heart is then placed into the chest and connected by quick connects which are similar to…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

Cerebrovascular Accident (CVA), also referred to as a “stroke” is a life-threatening medical condition that occurs when there is diminished blood flow being delivered to the brain. The two major types of strokes are ischemic and hemorrhagic. An ischemic stroke occurs when there is an obstruction in the brain caused by a blood clot and a hemorrhagic stroke results in sudden bleeding in the brain when a blood vessel ruptures. National Institute of Neurological Disorders [NIND] (2011) reports that…

Pulmonary Fibrosis is a very serious disease in which most people live from 3-5 years after being diagnosed. Regular Pulmonary Fibrosis, abbreviated as PF, is a disease in which your lungs become scarred, and when they scar they do not heal. The tissue deep inside lungs becomes thick and stiff. The scarring is called fibrosis, and pulmonary means of or relating to the lungs. The scars make it difficult for the oxygen to pass through the air sacs into the bloodstream. The damage is visible by…

If the subject held their breath after hyperventilation, they would be able to hold their breath longer than after hypoventilation. The reason this is true is because when you are hyperventilating, you are taking in more oxygen, so when you hold your breath, you will have more oxygen stored in your body to use. This is the reason free divers hyperventilate before going on a dive, to store oxygen. Hyperventilation is when someone is breathing in a quick manner. Apnea vera is a pause in breathing…

expectancy. Risk factors for hypokinetic diseases include your body weight. The more mass your body has, the more blood is needed to make sure your body is receiving enough oxygen and nutrients. Since more blood is being pumped through your body, your artery walls are experiencing more pressure. Your body mass also influences how efficiently and effectively your body is…

Heart Failure Many people come across the word “heart failure” and automatically become scared or anxious at the idea of their heart no longer being useful. The truth is, although it is definitely something to stay aware of, heart failure only means that your heart has encountered a difficulty when it comes to pumping blood normally. There are multiple forms of heart failure some which are included are, left side failure, right side failure, diastolic failure systolic failure and congestive…

The blood is a fluid connective tissue which is unlike most connective tissues taking form in solid aggregation of cells. With this characteristic, it is able to serve specialized functions for the body. First of the many functions of the blood, it serves as the medium of distribution of oxygen and nutrients to cells in our body. The hemoglobin found in the erythrocytes of the blood are the oxygen carriers that will bind oxygen from air inspired and will release it to the cells once the blood…
