The cardiac cycle is the coordination of the filling and exhausting of blood by electrical signals that cause the heart muscles to contract and unwind. The contraction of the heart is directed by a nerve drive that goes from the SA node to AV node to AV group to Purkinje fibers to the myocardium. Amid the cardiac cycle, the heart contracts by means of systole, pushing blood out of the heart, and unwinds through diastole, filling the heart with blood. Cardiomyocytes, or cardiac cells, are striated and are in charge of the pumping of the heart; they are the main muscle cells with intercalated plates. The heart's inner pacemaker controls and times the thumping of the heart by means of electrical signals.

In “Exploring the Managed Heart,” Hochschild observes that modern day labor has developed into occupations that require not only physical labor, but also emotional labor. Emotional labor as a method of profit maximization not only makes the worker’s obligations more ambiguous and more demanding, but also makes workers more susceptible to experience emotional distress. The author argues that the majority labor in the workforce evolved from involving purely physical labor to requiring more, such as emotional labor. Hochschild defines emotional labor as ‘the management of feeling to create a publicly observable facial and bodily display.’
In the image I created did you can see the main characters from when calls the heart Elizabeth Thatcher, Jack Thornton, Abigail Stanton, and Bill Avery. By adding the main characters to the image I wanted to create a sense of human connection as most often the audience tries to connect with the characters in someway. We tend to connect or find characteristics that remind us of ourselves, which result in us creating a deeper understanding and connection to the characters. When calls the heart is a family friendly show that teaches and talks about moral and important life stories throughout each episode. It creates a show that discusses realistic problems we face every day.
By the second, all of the heart beats slow. Bum… bum. Bum… … bum. Your hands ball into fists as you prepare to stop the heart beats for good, that is the only thing you have ever known how to do. And the only one who can bring the hearts of others to a beating end.
After the rollercoaster of emotions Hearties experienced last Sunday I think we deserved a much lighter episode this week, which is exactly what we got! This episode, entitled Healing Heart, picks up two weeks after Jack left for the North. We find Elizabeth having mixed emotions. She is happy knowing that she is engaged to the love of her life, but of course is worried for his safety and anxious not knowing when he'll return. We are also introduced to some more new faces, we learn more about Abigail's new cook, and we add business woman to Rosemary's list of many talents.
A dogged work of reminiscence by an author not naturally given to introspection, “Decision Points” lacks the emotional precision and evocative power of his wife Laura’s book, “Spoken From the Heart,” published earlier this year, though it’s a considerably more substantial effort than Mr. Bush’s perfunctory 1999 campaign memoir, “A Charge to Keep.” Certainly it’s the most casual of presidential memoirs: how many works in the genre start as a sort of evangelical, 12-step confession (“Could I continue to grow closer to the Almighty or was alcohol becoming my god?”), include some off-color jokes and conclude with an aside about dog poop? The prose in “Decision Points” is utilitarian, the language staccato and blunt. Mr. Bush’s default mode is
Everyday someone is saved by a doctor and it 's an exciting miracle. Why not be able to bring that feeling home with you? Medical TV shows have really hit the jackpot by harnessing that emotion of excitement, empathy, rage, and grief as they made this hot new genera. Some medical show’s are not realistic nor believable. Others, like the up and coming medical show “Heartbeat” is based on the life of a real person.
a. “The Tell-Tale Heart” Reading vs. Performance I greatly enjoyed both reading and listening to “The Tell-Tale Heart.” This story has so much character and such interesting events.

While Lincoln was able to very successful leading with the head, it is important to know that he did an even better job leading with his heart. It takes an extremely intelligent person to be able to lead with both the head and the heart, leading with the heart entails, mainly emotional intelligence. Being able to be emotionally intelligent gave Lincoln the upper hand when it came to leading an entire country.

Physiology of Heart Rate Cardiovascular system generally is defined as the circulation of blood throughout the body to supply oxygen and nutrients and removal of waste products [1]. In addition, heart rate refers to the amount of times the heart beats per minute. The heart beats allows the blood to be pumped out of the heart and into the body supplying oxygen in order for the muscles to work or to the lungs for re-oxygenation [1]. A normal resting heart rate ranges from 60-100 beats per minute (bpm). Generally, when the heart rate is higher than 100 beats per minute (bpm) it suggests that the heart is working hard to supply blood throughout the body and this could also be an indication of a serious problem [1].
They combine together to form the various cardiac muscle fibers and the environment surrounding the blood flow inside the muscle. When the heart is pumping, it is doing work against the pressure, the friction between the various components like the muscle fibes, the blood cells, striking of the blood against the blood vessels, closure of valves etc leads to generation of heat and increase
