    PRACTICAL EXERCISE 4 HEART STRUCTURE AND CIRCULATION. 1 Describe the heart sounds you hear. Explain the origin of two sounds. Two heart sounds are normally heard through a stethoscope on the chest wall, 'lab' 'dap'. The first sound can be described as soft, but resonant, and longer then the second one. This sound is associated with the closure of AV valves (atrioventricular valves) at the beginning of systole. The second sound is louder and sharp. It is associated with closure of the pulmonary ...

    The gasoline engine has changed the world forever. When Karl Benz improved the internal combustion engine and put it into an automobile he started something that to this day is still being improved on. The Germans are known for there fine luxury vehicles, but it's America that wants bigger and better. Americans have raced their automobiles from the time before Henry Ford rolled his first car of the assembly line. The basic principle of the gasoline engine is the fuel is mixed with air in the car...
  • Valves Valve Flow Common
    363 words
    Valves The primary purpose of a valve is to direct the flow of fluids by starting, stopping, and throttling flow to make modern processing possible. Valves are designed to withstand pressure temperature, and flow, and can be found in homes and industry across the world. The most common valves found in the manufacturing industry are gate, globe, ball, check, butterfly, plug, needle, three-way, diaphragm, relief, angle, and multiport. All valves are selected for a specific purpose. Valves are clas...

  • Red Blood Cell Report
    565 words
    A red blood cell can start in the big left toe of a person and travel all around the body, ending up in the same place it started. During the entire transportation process, the Red Blood Cells transport oxygen from the lungs to the body tissues and carbon dioxode from the body tissues to the lungs. Red blood cells can be found in every part of the body because they are so widely spread out. Starting at the big left toe of a person, a deoxygenated red blood cell moves through many blood vessels s...

    The ascending aorta, or aorta ascend ens, along with its constituents, amounts to about five centimeters in length. It constitutes the initial division of the aorta, the largest artery in the body. It originates from the upper portion of the left ventricle of the heart at the aortic valve "on a level with the lower border of the third costal cartilage behind the left half of the sternum; it passes obliquely upward, forward, and to the right, in the direction of the heart's axis, as high as the u...

    Nick BenavidezPhysiology of Exercise Dr. Larry Rogers Heart Disease You need your heart for all your body needs. It pumps about 2000 gallons of blood a day. It takes about 20 seconds for blood to reach every cell in the body. An artery carries blood out from the heart. A vein carries blood back to the heart. An average adult heart weighs about 10-13 ounces (300 to 350 grams). The rate which the heart pumps varies depending on what your doing. When at rest the heart pumps more slowly. When you r...

  • Charging Valve Air Cycle Braking
    3,280 words
    Using an electric hybrid leads to a significant improvement in vehicle fuel economy. Unfortunately, it also leads to a substantial increase in cost. Regenerative compression braking offers another way to achieving the same objective without incurring the same cost penalty. With some modifications, the vehicle engine can perform both absorption and recovery of braking energy, using compressed air for energy storage. The process parallels the one employed by electric hybrids, but it requires none ...
