The Human Heart Acts A Pump

- The human heart acts a pump and it contains four chambers: two atria, which receive venous blood, and two ventricles, which pump blood into the arterial system. Arteries carry blood away from the heart and veins carry blood to the heart. Atria are the upper chambers and ventricles are the lower chambers of the heart. The flow of blood is as follows. Blood, with low oxygen and high carbon dioxide content, returns to the right atrium of the heart from the body via the inferior and superior vena cava, which are the largest veins in the body....   [tags: Heart, Blood pressure, Blood, Artery]

Treatment Of Coronary Artery Bypass Grafting

- Discussion: Treatment of coronary artery bypass grafting has developed rapidly over the last decades. One of great improvements was the introduction of off-pump coronary artery bypass grafting. It revolutionized the surgical approach by reducing the cost of surgery; and decreased the morbidity association with cardiopulmonary bypass. However, dysrhythmia is a common feature during off-pump CABG due to many reasons (e.g., mechanical stimulation of the heart, myocardial ischemia and electrolyte abnormalities including hypomagnesaemia) [17]....   [tags: Myocardial infarction, Atherosclerosis]

Laser Doppler Anemometry

- The purposes of this experiment are: 1. To determine the shape of the wake behind the cylinder. 2. To determine the water tunnel calibration. Both of these objectives were accomplished by using LDA (Laser Doppler Anemometry). LDA is one of the main velocity measurement methods used in professional experimentation. Light beams are shot from a laser onto flowing water. In objective one, a cylinder was submersed in the water flow to determine how the velocity aft of the cylinder was disturbed. While the second objective used the LDA on flowing water with no disturbances....   [tags: Physics Essays]

- Opercular pumping is a mechanism utilized by certain fish for gas exchange. An opercular pump is used to pump water through the gills in an almost continuous unidirectional flow (SHSU). A dual pump is used in tandem in order to drive the unidirectional flow, both a buccal cavity and opercular cavity work simultaneously. The oral valve along the buccal cavity opens, allowing an influx of water. This influx of water causes an expansion of the opercular cavity, dropping the pressure (Hall). Water then enters into the opercular cavity and flows out due to opercular cavity compression....   [tags: Blood, Oxygen, Viscosity, Turbulence]
