Question
Visit the Internet and research how an artificial heart works. Use the Internet to research how an artificial heart works. Visit at least three different websites that you think are credible Post your responses to the discussion board Post responses to the following questions and, it appropriate, include personal experience as part of your answers. Compare the human heart structure and function with the artificial heart structure and function. Answer at least two of the following questions: What structures found in the human heart are used in conjunction with the artificial heart? What is the main functional difference between the human heart and the artificial heart? What impact does this difference have on the amount of oxygenated blood available to the body? List the four cardiovascular system structures to which the artificial heart is connected. What are the requirements a person must meet to be considered as a recipient of an artificial heart? Do you agree with this list of requirements? Do you believe that other requirements should be added? Are there requirements that should be removed? Explain your thoughts. Read other students posts and respond to at least two other studentsExplanation / Answer
STEP1
Heart is a muscle that pumps blood around our body. It has four chambers: the left and right atria (blood receiving chambers),the left and right ventricles (the blood pumping chambers). When heart gets failed, it is replaced by an artificial device which exactly pumps the blood around our body like left and right ventricles.
An artificial heart that provides an extra ventricle (pumping chamber in your heart) to help to pump blood around your body. This is called a ventricular assist device (VAD). A VAD is made from metal and plastic, and has a small pumping chamber lined by a special material that stops blood clots forming. It may be put into our body or lie outside your body, depending on what type of artificial heart is being used.
An artificial heart maintains the heart's blood circulation and oxygenation for varying periods of time. The ideal artificial heart must beat 100,000 times every 24 hours without requiring either lubrication nor maintenance and must have a constant power source. It must also pump faster or slower depending on the activity of the patient without causing either infection or blood clots.
