Cyanosis is the abnormal blue discoloration that occurs in the skin and mucous membrane by an increase in the deoxygenated hemoglobin levels to 5 g/dl. People with anemia do not develop cyanosis until the oxygen saturation(SO2) has declined to lower levels than for a person with normal hemoglobin levels as well as people wth polycythemia exhibit cyanosis at greater oxygen saturation levels, Cyanosis can be classified into either central or…

For the Anatomy of the Heart Guide Physiology of the Heart Coronary Systole Diastole At any time the chambers of the heart can be on one of two different states. Systole – The Cardiac muscle tissue is contracting to push blood outside the heart chamber. Diastole – During this state, the cardiac muscle cells relax to enable the chamber to fill with blood. There is an uptick in blood pressure…
The heart is a muscular organ that is around the size of a closed fist that pumps blood throughout the body, functioning as the circulatory pump. It takes the deoxygenated blood through the veins and sends it to the lungs for oxygenation before injecting it into the different arteries, which drove oxygen and nutrients to the body tissues transporting the blood through the body. The heart is positioned in the…

In an international ten year study by the National, Lung and Blood Institute, heart failure patients with clogged arteries have a better chance of surviving ten if they get surgery plus medication rather than just medication alone. Early results from the same research study, the question was raised about the benefits of bypass surgery versus receiving medicine alone. However, research in the long-term study says evidence clearly favors getting surgery….
Pericardial disease, or pericarditis, is the inflammation of any of layers of the pericardium. The pericardium is a ten tissue sac that surrounds the heart and consist of the following parts. Visceral pericardium – an internal layer that envelopes the entire heart. A middle fluid layer to prevent friction between the visceral pericardium and parietal pericardium. This layer extends s to the beginning of the great vessels begin of the…
