by the relative pressure differences between the semi-lunar valves and the high pressure level that was generated in the ventricles. This is when both the ventricles contract to deliver the blood into the pulmonary and systemic circulation by the shortening of muscle cells. After a duration of about 150 msec when ventricle contraction reaches a peak the ventricular pressure starts decreasing quickly. During this time the semi-lunar valves are shut due to blood from the aorta and pulmonary trunk flowing

When your heart contracts and forces blood into the blood vessels‚ there is a certain path that the blood follows through our body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. As the heart pumps‚ blood is pushed through our body through the entire circulatory system. Oxygenated blood is pumped away from the heart to the rest

7. Use the poker stick to push your way through the openings in the right side‚ like the right ventricle‚ superior vena cava‚ inferior vena cava‚ and the pulmonic valve. 8. Cut open the left side of the heart using a scalpel or scissors‚ so that you can see the different structures that are on the left side like the aortic valve and the let pulmonary veins. 9. Finish observing the inside of the heart. 10. Clean up; throw away the heart‚ clean off the tools used‚ and disinfect the area used

and expansion was used to investigate this modification. By changing the exhaust valve closing timing during the exhaust stroke‚ the optimum amount of exhaust can be recompressed‚ maximizing the net mean effective pressure of the steam expansion stroke (MEPsteam). The valve closing timing for maximum MEPsteam is limited by either 1 bar or the dew point temperature of the expansion gas/moisture mixture when the exhaust valve opens. The range of MEPsteam calculated for the geometry of a conventional gasoline

Switch on the pump and let the water flow for one minute or until all air has been expelled from the pipe work‚ then switch off the pump. 4. Close both the inlet and flow control valves. Let the vent and drain valves of the six tubes manometer opened. 5. Now immediately close vent and drain valves. 6. Adjust the height of the manometer tubes by slightly opening and closing vent and drain valves until the height
