Introduction: In this experiment, cardiovascular fitness is being determined by measuring how long it takes for the test subjects' to return to their resting heart rate. Cardiovascular fitness is the ability to "transport and use oxygen while exercising" (Dale 2015). Cardiovascular fitness utilizes the "heart, lungs, muscles, and blood working together" while exercising (Dale 2015). It is also how well your body can last during moderate to high intensity cardio for long periods of time (Waehner 2016). The hypothesis is that people who exercise for three or more days will return to their resting heart rate much faster than people who only exercise for less than three days.

Blood vessel length, when increased causes more friction or resistance thus making it more difficult for blood to flow through the vessel. In summation, increasing blood vessel length inversely effects flow rate but decreasing flow rate. My prediction was that an increase in blood vessel length would inversely effect blood flow. As evidenced in this experiment, with the increase of the blood vessel length, there was a decrease in blood flow.

In the story The Tell-Tale Heart by Edgar Allen Poe, The author puts a lot of emphasis on the heart. But what can we infer about the heart? In the story Poe’s character claims to the audience that he was very nervous about the situation but was not insane. He claimed to have a ‘disease’ that made his hearing extra sensitive.  Every night the narrator suspiciously stalks this old man who has this mysterious blue eye with a film over it. The narrator soon feels entrapped by this eye and decides to kill the old man to be set free.

This experiment was carried out as noted about in Procedure 1. The resting heart rate was established and used as a baseline value from which to compare all future deviations. While data could

In the short story “Tell-Tale Heart” written by Edgar Allan Poe, there are two main characters- the narrator (perceived as insane) and the Old Man (perceived as innocent). The narrator is disturbed by the Old Man’s “vulture eye” and therefore murders him. After the murder, the narrator dismembers the Old Man and buries him under the floorboard. When the intrepid narrator is questioned by the police of a scream a neighbor overheard, the narrator courageously invited the officers in. During the duration of the officer’s stay, the narrator begins to hear the heart he or she has buried under the floorboard; the escalating sound of the heartbeat causes the narrator to ultimately confess to the murder of the Old Man. Poe uses various literary devices to portray the narrator’s insanity in the short story “Tell-Tale Heart.”

In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary valve and into the pulmonary trunk. Blood is then distributed from the right and left pulmonary arteries to the lungs, where carbon dioxide is unloaded and oxygen is loaded into the blood. The blood is returned from the lungs to the left

Has a vulture eye cause mental disorder on someone? First off, The tell-tale heart by Edgar Allen Poe explains about a murder an unmade narrator committed and convince all readers about his sanity. The unnamed narrator start off by explaining the story that he’s is nervous but not mad. Next, the author uses plot, theme to create the story with anxiety by saying he want to kill the old man. The narrator wants to kill the old man because he can’t stand to see his ugly evil eye of a vulture. In the tell tall heart it illustrates that a person may act and talk normal but in the inside of his body he acts in a mental illness state of mind. By simply answering these question, how is the story relevant in historical, social,

Great post. I like the points you outlined about assessment of Mr. J. You started with maintaining ABC’s to checking lower extremities pulses to ensure that it is not cut off by the tight constrictive band of the eschar. ECG should be monitored at least the first 24 hours because Mr. J is prone to cardiac arrest due to high electrical voltage injury. Fluid resuscitation with 14 or 16 gauge preferably through unburned tissue, and infusion of lactated Ringer’s solution will help to prevent shock. Assessment of vital signs and pain is very important, the nurse should also assess for history of tetanus immunization because burn wounds are prone to tetanus. Mr.’s brief medical history is important in case he has any allergies, current medical

Complete recovery of the heart rate may take an hour after light activity, several hours after long-duration aerobic exercise, and perhaps 24 hours after intense exercise. One easy way to measure HRR is to measure the change in heart rate during the first minute after submaximal exercise: a drop in heart rate of 15-20 beats per minute might be typical and a value less than 12 would be unfavorable.

The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat.

During inspection of the heart assessment observe abnormal finding. Inspect the jugular vein and the carotid artery. Note pallor or cyanotic skin color, temperature, turgor, texture, and clubbing of finger. Observe for swelling, edema and ulceration. Clubbing is a sign of chronic hypoxia caused by a lengthy cardiovascular or respiratory. Poor cardiac output and tissue perfusion is noted by cyanosis and pallor. For dark-skinned, inspect his mucous membranes for pallor. Decreases or absent of pulse with cool, pale, and shiny skin, and hair loss to the area, and the patient may have pain in the legs and feet may indicate arterial insufficiency. Ulcerations typically occur in the area around the toes, and the foot usually turns deep red when dependent

This allows your cardiovascular centres in your brain a little bit more latitude as far as controlling your heart rate. If you were to remove a beating heart from someone's body you would find that the heart is no longer being suppressed by the parasympathetic nervous system and it will accelerate to the same pace as the sinoatrial node. The SA node generates action potentials approximately 100 times per minute due to the physiology of the heart, its own permeability to sodium and calcium via its channels, and a host of other things. Anywhere between 80 to 100 beats per minute is normal for the SA node.

The heart is one of the most important organs in an organism’s body, no matter if they are aquatic, amphibian, or a mammal. This super organ works automatically, able to pump massive amounts of oxygen rich blood through the body by means of electrical impulses and the opening and closing of valves within its many layers. It is what keeps us and every other creature on this earth alive; so it is only natural for one to fear when there might be a problem with one’s heart. A cardiac arrhythmia can happen to anyone, no matter the age, race, or gender, and as such, doctors and scientist have spent years trying to better understand the heart and the way it functions so that they can try to prevent these problems and save millions of lives.
