One of the remarkable features of the heart, which is about the size of a fist, is that the pumping action or contractions (- 70 times/min) of atria and ventricles are simultaneous. Deoxygenated blood is pumped out to the lungs from one side of the heart at the same time oxygenated blood is pumped out from the other side to the aorta and onward through the body. The entire process of blood flow between the atria, ventricles, and the principal vessels is in unison, controlled in part by four one-way valves. The atrioventricular valves, tricuspid on the right and mitral on the left, prevent blood from flowing... 

In addition to its internal blood flow operation, the heart has its own system of blood vessels to keep the muscle wall of the heart, the myocardium, supphed with oxygenated blood (Fig. 3a). The coronary arteries, which branch from the aorta to the right and left sides of the heart, are vital to maintaining that supply. The heart is an extraordinary electromechanical muscle that can be trained to increase blood flow to the body sixfold. It can range from 5 to 30 L /min during exertion. 

There can be a number of underlying causes of CHE. The most prevalent is the lack of oxygenated blood reaching the heart muscle itself because of coronary artery disease with myocardial infarction (111). Hypertension and valvular disease can contribute to CHE as well, but to a lesser extent in terms of principal causes for the disease. 

The liver is a wedge-shaped organ of some 1.5 kg in adult humans, which, in terms of blood circulation, is interposed between the gastrointestinal tract and the rest of the body. The blood supply to the liver is from the hepatic portal vein (80%) and the hepatic artery (20%), the former bringing a rich supply of nutrients direct from the intestinal tract and the latter supplying the liver with oxygen. Blood drains from the liver by the hepatic vein. The position of the liver enables it to act as a processor of the absorbed nutrients, and to control their storage... 

Ischemic heart disease (IHD) is also called coronary heart disease (CHD) or coronary artery disease. The term ischemic refers to a decreased supply of oxygenated blood, in this case to the heart muscle. Ischemic heart disease is caused by the narrowing of one or more of the major coronary arteries that supply blood to the heart, most commonly by atherosclerotic plaques. Atherosclerotic plaques may impede coronary blood flow to the extent that cardiac tissue distal to the site of the coronary artery narrowing is deprived of sufficient oxygen in the face of increased oxygen demand. Ischemic heart disease results from... 

The hepatic artery supplies the liver with 300 ml/min of oxygenated blood from the aorta. The remaining 1050 ml/min of blood flow is delivered by the hepatic portal vein. This blood comes directly from the digestive tract. It is low in oxygen but contains a high concentration of nutrients absorbed from the intestines.

Oxy-Hb Crosses the y axis near the deoxy-Hb line but falls steeply around 600 nm to a trough around 660 nm. It then rises as a smooth curve through the isobestic point where it flattens out. This curve must be oxy-Hb as the absorbance of red light is so low that most of it is able to pass through to the viewer, which is why oxygenated blood appears red. 

Q is the flow rate of unreacted hemoglobin and Qg its value at the fiber entrance. Oxygen diffusivity through oxygenated blood Dq at 37 °C can be estimated, for example, by Equation 15.10 [9] or by Figure 15.4a... 

The chemical properties of nitric oxide,—Nitric oxide is not combustible, and it supports the combustion of a few substances, but not that of a candle. Nitric oxide is irrespirable since, in the presence of air, it forms brown fumes of nitrogen peroxide. L. Hermann 6 said that oxygenated blood is darkened when shaken with nitric oxide, and it seems to form a nitrosylhcemaglobin. W. Manchot discussed the compounds formed by nitric oxide with blood. F. Hatton showed that the bacteria which are connected with the putrefaction of meat extracts develop quite well in an atm. of nitric oxide. 

Oxygenated blood is transported to the cells where it is used for the oxidation of food to carbon dioxide, water and other products.

The patient s vital signs provide the most sensitive indicator of response to therapy and normalisation of heart rate, respiratory rate, oxygenation, blood pressure and temperature should be confirmed. Laboratory markers of infection such as CRP and WCC should be monitored to ensure normalisation. Failure to improve may indicate an incorrect diagnosis, a resistant pathogen, poor absorption of antibiotic, immunocompromise or local or distant complications of community-acquired pneumonia such as lung abscess.
