  • Thrombosis is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Alternatively, even when a blood vessel is not injured, blood clots may form in the body if the proper conditions present themselves. If the clotting is too severe and the clot breaks free, the traveling clot is now known as an embolus

  • The main method of cognition of the performance of biological systems is their mathematical modeling. The essence of this method should reflect the principle of optimization in biology[9]. Any biosystem cannot function if its energy consumption is inadequately high. The same is applicable to the blood circulatory system. Its main function is to transport blood throughout the body in order to maintain the proper gaseous exchange, deliver important substances to viscera and tissues in living body and remove decay products.

  • In January 2005 Peg McQueary nicked her ankle while shaving. It was a tiny cut, but that little opening in her skin provided a perfect entry point for dangerous bacteria. Two weeks later McQueary developed a pus-filled boil on her ankle. Shortly thereafter, her leg swelled to three times its normal size. It was hot, tender, and painful. McQueary went to see her doctor. He rushed her to the hospital, where she was intravenously administered vancomycin, a powerful antibiotic. It took more than a month for Mc- Queary’s leg to heal....

  • Although the part of our bodies most affected by air pollution is the respiratory system, the circulatory system can also be affected. Exposure to unhealthy levels of air pollutants can result in low oxygen levels in red blood cells, abnormal heart rhythms, and increased risks of blood clots and narrowing of blood vessels. These effects can lead to worsening of heart diseases such as heart failure and increased risks of heart attacks or strokes. The Pollutants Chart: Sources and Effects of Air Pollutants summarize the sources and health effects of criteria air pollutants.

  • Volume 3 of the book series Biomathematical and Biomechanical Modeling of the Circulatory and Ventilatory Systems aims at presenting major sets of signaling receptors mainly located at the plasma membrane, 1 in a modeling framework rather than biological perspective. Collecting signaling effectors, their main interactions, and major properties are the first tasks required for any modeling of cell signaling processes. The major objective is to comprehend the complexity of natural phenomena to model these events. In other words, to yield the maximal amount of known information (i.e.

  • In general, the health status at old age has an important individual and social relevance. The vulnerability is increasing by physiological and morphological changes in the organism and central nervous system during the ageing process. The indicators of physiological health are based on prevalence of disabilities and causes of death. In Germany the main causes of death are circulatory diseases, neoplasms, diseases of respiratory system and diseases of digestive system (Statistisches Bundesamt 2007a; Nolte, Shkolinikov & McKee 2000).

  • Death and Dying The most common causes of death in patients with cancer are infection (leading to circulatory failure), respiratory failure, hepatic failure, and renal failure. Intestinal blockage may lead to inanition and starvation. Central nervous system disease may lead to seizures, coma, and central hypoventilation. About 70% of patients develop dyspnea preterminally. However, many months usually pass between the diagnosis of cancer and the occurrence of these complications, and during this period the patient is severely affected by the possibility of death. ...
