    parts that work together to operate the heart’s muscles and control the heart’s speed. The three parts are called the generator, the lead, and the electrodes. The generator, which is like the central command of the pacemaker, generates electrical pulses. The generator contains a battery that is expected to last up to 10 years and then will need to be replaced. The leads are wire-like pieces that are inserted into a vein that leads into a chamber of…

    the pulmonary circuit. The left side of the heart is dedicated to taking the blood from the lungs and pumping it to the rest of the body. This is the systemic circuit. We are able to measure how fast the heart in contracting by taking arterial pulse. To do this you locate the radial artery running through the forearm. When you press down with the tips of your fingers you are able to feel the pressure passing through that…

    rhythm of the heartbeat has a defect. To correct this a pacemaker can be used. A pacemaker is a small device that is placed in the chest or even the abdomen that is used to control abnormal heart rhythms. The pacemaker uses energy electrical (low) pulses to prompt the heart to beat at a normal rate. There are four valves in the heart which prevents the backflow of blood. They are the bicuspid valve, tricuspid valve, aortic semilunar valve and the pulmonary semilunar valve. The bicuspid…

    and to isolate the gastrocnemius. Both experiments used LabChart to perform various stimulations on the sciatic nerve and the gastrocnemius muscle to observe the level of intensity, contraction, and voltage threshold caused by different stimulation pulses. Introduction When a neuron produces an action potential it could be due to chemical…

    astronomers took an interest in this occurrence and decided to monitor the Crab Nebula for pulsed radio emissions. They found high intensity pulses originating from the central strange star, and were therefore able to identify it as a pulsar. They later discovered that the giant pulses they observed, occurred every two minutes or so, and that the true pulse period was as short as 33 milliseconds. This discovery discarded white dwarfs from the possibility of being pulsars, as radial oscillations…

    from a two-chambered heart of a fish to a four-chambered heart in mammals (Harris-Haller, 229). The purpose of the experiment is to study the cardiopulmonary function of humans. Collecting data from a spirometry, electrocardiogram, blood pressure, pulse, and respiratory rate, the anatomy and physiology of the heart and lungs will be understood. The null hypothesis is the health of the lungs and heart can be determined by the spirometry test, the electrocardiogram test, and the…

    from 60 to 100 beats a minute. To count your pulse rate (a.k.a. heart rate), the ideal time is when you first wake up in the morning or at least before you leave the bed. Locate your pulse on your wrist or at your neck by using your index and middle fingers together and then count the beats that occur within one full minute (monitor using second hand of the watch, or start and stop at change of the minute digit in the flat panel display – do not count pulse only for 10 seconds and then multiply…
