Homeostatic Mechanism Essay Example for Free

Homeostatic Mechanism Essay Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state, while the world around it is changing constantly. There are many steps in the process of homeostasis. First, there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center, which decides the response. The information entering into the control center is called the afferent pathway. During the efferent pathway, the information is sent out from the control center to the effector. The effector provides the means for the control center’s response, returning the body back to normal. An example of a homeostatic mechanism working is someone exercising, or running. This is known as the stimulus in the homeostatic mechanism. Consequently, the person is now breathing faster, their body temperature is rising, and their heart rate is increasing. By breathing faster, more carbon dioxide is entering into the body. This causes the pH level of the blood to decrease, making it more acidic. HHHhhhhdkjfkldsdjf The receptor detects this change and sends the information out to the control center. The control center then tells the cells to get rid of the carbonic acid in the blood. This causes the person to breathe even faster, prompting more oxygen into the body, getting rid of the carbonic acid. When the person stops running, the heart rate starts to return to the resting heart rate. The pH level of the blood also increases back to normal, which is about 7.35 pH. A homeostatic mechanism is basically a test of a person’s responsiveness. Without any homeostatic mechanism, the body would fill up with carbon dioxide and could pass out and die. A homeostatic mechanism in a body is necessary to maintain a stable condition.

Daddy by sylvia plath Essay -- essays research papers fc

In the poem â€Å"Daddy†, Sylvia Plath says that there are women who, due to early conditioning, find themselves without the tools to deal with oppressive and controlling men. They are left feeling helpless and hopeless. For some women, the struggle is never resolved, others take most of a lifetime. For a lucky few, they are granted a reprieve. The speaker in this poem is Sylvia Plath. The poem describes her feelings of oppression and her battle to come to grips with the issues of this power imbalance. The poem also conjures the struggle many women face in a male dominated society. The conflict of this poem is male authority and control versus the right of a female to be herself, to make choices, and be free of male domination. Plath’s conflicts begin in her relationship with her father and continues with her husband. The intensity of this conflict is extremely apparent as she uses examples that cannot be ignored. The atrocities of NAZI’ Germany are used as symbols of the horror of male domination. The constant and crippling manipulation of the male, as he introduces oppression and hopelessness into the lives of his women, is equated with the twentieth century’s worst period. Words such as Luftwaffe, panzerman, and Meinkampf look are used to descibe her father and husband as well as all male domination. The frequent use of the word black throughout the poem conveys a feeling of gloom and suffocation. Like many women in society, we know that Plath felt oppressed and stifled throughout her life by her use of the simile â€Å"I have lived like a shoe for thirty years poor and white, barely able to breath or Achoo.† The use of similes and metaphors such as â€Å"Chuffing me off like a Jew. A Jew to Dachau, Auschwitz, Belson.† and â€Å"I think I may well be a Jew† clearly shows the feelings of anguished hopelessness and the ripping agony she must have felt. The agelessness of this poem is guaranteed as there will always be women who feel the same torture that is described. . Strong images are conveyed throughout the poem. The words â€Å"marble- heavy, a.bag full of God† conveys the omniscience of her father’s authority and the heaviness it weighed on her throughout her life. â€Å"The vampire who said he was you, and drank my blood for a year, seven years if you want to know† describe her husband and the ability of male power to strip a person of their own sen... ...trol extreme mood swings with ESB.(Coulman 679) While scientists continue to investigate exactly what electricity does to the human brain, they still use it as a form of therapy.

Macbeth †Closing Address to the Jury, Prosecution. Essay

Good morrow esteemed lords and ladies of the court, it is within my regrets to tell you that our â€Å"noble† thane (of both Glamis and Cawdor) and King Macbeth has murdered our fair (late) King Duncan for his own traitorous and greedy purposes. Macbeth has betrayed his country and committed regicide, the highest form of sacrilege. The prosecution has found Macbeth guilty beyond a reasonable doubt, with several accounts of murder, manslaughter, attempted murder, one account of regicide and conspiring to murder. (accessory to murder) 😛 Macbeth is a murderous heathen, whom sought to heighten himself to the rank of King by betraying the country (already stated this), his King and god. An earlier witness; one of Macbeth’s â€Å"Loyal† servants, (the gentle woman) stated that he had heard Macbeth whispering â€Å"I go, and it is done. The bell invites me. Hear it not, Duncan, for it is a knell that summons thee to heaven or to hell.† Obviously scared of Macbeth’s murderous mind, the servant stayed quiet until now. There were more witnesses as of yesterday, as a cutthroat hired by Macbeth told the jury of the atrocities he had performed, before being dragged off to be executed. To quote; the murderer said â€Å"Macbeth threatened me with a certain death if I were to betray him. That was just a shimmer of the murderer within him.† The prosecution would also like to point out that straight after Duncan’s body was found, Macbeth killed the two intoxicated guards, blaming these poor innocent men for the murder, and also dispatching of two possible witnesses. Macbeth did also state â€Å"O, yet I do repent me of my fury, that I did kill them.† In stating â€Å"them†, Macbeth could have been referring to both the murdered slaves and our fair King Duncan. Macbeth also insinuated that the drunken guards murdered Duncan in his sleep, but if you look and think, and I am sure you are all intelligent Lords and Ladies, a drunken guard cannot harm more than a fly (people who are drunk are more likely to become very aggressive), as they would not be able to stand. In an earlier testimony, we called upon Lady Macbeth, who, when confronted with the evidence and questioning, cracked under pressure and confessed her hand in murdering Duncan. Lady Macbeth acknowledged Macbeth and herself plotting to murder Duncan, Banquo, and MacDuff’s wife and children. Macbeth also attempted to murder Fleance and MacDuff. A servant came forth and stated that Lady Macbeth had whispered to Macbeth â€Å"Infirm of purpose! Give me the daggers. The sleeping and the dead, are but as pictures. ‘Tis the eye of childhood, that fears a painted devil. If he do bleed, I’ll gild the faces of the grooms withal, For it must seem their guilt.† Lady Macbeth obviously did not know she was whispering loud enough for the Servant to hear. Unfortunately, Lady Macbeth has passed away now, taking her life before more answers arose. The defence earlier tried to state Macbeth was acting under the influence of three evil witches. They stated that the witches had told him â€Å"All hail, Macbeth, that shalt be king hereafter!† According to the defence, this justifies treason, heresy, murder and plotting against the crown. The court was lucky (luck is not a part of their nature) enough to get one of the Witches (Weird Sisters and they don’t listen to petty human demands and/or requests) in the room, whom stated that â€Å"Macbeth sought to murder King Duncan on his own accord; we witches merely stated he would be King.† The Witch denied fuelling Macbeth’s murderous tendencies. MacDuff, slayer of the late Macbeth, retold the account of his family’s murder, which was issued by Macbeth. He stated to the court that his wife and son were in the midst of talking when a murderer ( he wasn’t there when they were murdered he had heard news of it but never witnessed it ), sent by Macbeth shook the residence by declaring that he was a traitor. He stated that his son, a brave young lad, meant to protect his father’s name. His honourable son screeched at the Murderer, â€Å"Thou liest, thou shag-eared villain!† This was followed by a fatal stab to his son, in which Lady MacDuff ran, shouting murder. The villainous murderer sought after Lady MacDuff, who could not outrun the murderous lunatic. MacDuff was severely shaken during this testimony, for reasons obvious to the court. He also recounted the end of Macbeth, in affirming â€Å"I held his head†¦ I held the head  of the treacherous king. I had to do it; he slaughtered my family, my life! I regret to say I enjoyed it, enjoyed taking back what he took from me.† If this does not prove the guilt of Macbeth, I do not know what does. As the court can see, the mind inside of Macbeth was a sickening one, as he ordered the slaughter of innocent people, to secure his position as King. In all these dishonourable acts, I believe it is in the interest of the court to say that Macbeth is guilty of multiple accounts of treason, murder, attempted murder, manslaughter, regicide and heresy. I thank you, esteemed lords and ladies, for your time in this period of turmoil. May King Duncan rest in peace, and the wicked Macbeth burn for his crimes.

The Public Understanding of Science and the...

In our society science has always been prominent in our development and existence in one way or the other. We are surrounded by things we do not fully except, and sometimes not fully understand, and because of this in our current times a separation grows between the scientifically learned and the uneducated in science. In this essay I will discuss the overlapping effect and influence of the public understanding of science in the advancing world; As well as its prominent issues of the psychological outcomes in confrontational incidents involving opposing views in scientific relations. To help describe this complicated view of science I will be referring to the article written by Brian Wynne the Misunderstood misunderstandings: social†¦show more content†¦As well as the understanding of science one must observe the issue of trust. The relationship between the scientists and general public and in the articles cases the scientists and farmers, we will observe is uprooted and eve ntually leads to the breakdown of the presence of the dominant model in the scenario; providing an isolated and intriguing look at a breach in the standard view; And the result of it. Brian Wynne’s article covers closely the public interactions of science through the observation of the hill sheep farmers in England situated in the northern Lake District of Cumbria. It covers their dealings with the Chernobyl nuclear incident in 1986, and the effects of the fallout caused by the radioactive cloud that drifted over the rural area. The fallout deposited radioactive Caesium isotopes through the rain into the ground, in turn radiating the large sheep population situated in the northern farms of Cumbria, and outlying areas. The farmers quickly observed disconcerting changes in their flocks, and suspected the radiation from the Chernobyl explosion to be the culprit, and as a result asked for assistance from the scientific community. This however was quickly dismissed initially by the Scientists as being an easily solved situation, and yet after six weeks in June a ban was implemented.
