Beating Heart

I looked down astonished at the beating heart before me. The surgeon attempted to clarify the procedure he was performing, but I was too busy trying to detect the clear string he was sewing in and out of the heart. I was in awe of his comfort with teaching an undergraduate student how to successfully execute a coronary artery bypass surgery, as if he knew I was interested in that specialty. He explained the condition of the patient and while I did not understand the terminology, I nodded with…

Cardiovascular Disease? (Heart & Blood Vessels) A heart and blood vessel disease (heart disease) is multiple problems within the heart one major one is called atherosclerosis. Atherosclerosis is a heart condition caused by a substance called plaque that build up on the walls of the heart arteries. This plaque buildup can narrow the hearts arteries making it harder for blood to flow through. When this problem starts to happen it can cause clotting which is able to stop blood flow and cause…

the chest that makes it difficult to breathe caused by poor blood flow to the myocardium) (the middle and thickest layer of the heart wall, composed of the cardiac muscle) (Miller, 2003). Upon checking his vitals the patient is noted to have an arrhythmia (when the speed or rhythm the heart is beating is not normal), while also suffering from tachycardia (when the heart beats exceeding fast, up to two hundred beats per minute in an adult). Consequently, review of his medical record shows…

perform well. Also, the carbon dioxide produced should be released from the body. It is the main role of the heart to pump harder and faster when exercising so that oxygen is taken in and carbon dioxide is released as a by-product. There are many acute changes that occur in this system before, during and after exercise. Heart rate anticipatory response- your nerves and adrenaline cause your heart rate to increase before taking part in sport activities. Before taking part in sport action, your…

Conclusion 1 : The degrees of exercise and the pulse rate are positively related. That means the pulse rate increases when the degrees of exercise increase. Explanation : - Pulse rate increases means the heart rate increases. - Heart rate increases means the frequency of the beating of heart increases. - Three reasons for the rise in pulse rate when the degrees of exercise increase. Reason ⅰ : To remove lactic acid in blood and skeletal muscle cells…

the brain, the heart is the most vital organ in the human body. The brain makes the heart function, but without a heart nothing else functions. In fact, in the absence of brain function, a human body can be kept alive for a surprising length of time as long as the heart can be made to beat. The heart pumps blood through 60,000 miles of blood vessels for a daily volume of 2,000 gallons of blood. That's enough to fill a 10 x 20-foot pool 10 feet deep, and the heart does this by beating 100,000…

I mean really feel it—a syrup coursing through your veins, yet not a syrup as it moves faster than blood. You know when it hits your heart because it starts beating faster, faster, faster, and then the feeling is gone. Then everything is gone—emotions, breath, sensation… Then there is silence. Silence.…
