The Baroreceptor Reflex and the Diving Reflex - 547 Words

The baroreceptor reflex and the diving reflex are both two great mechanisms that incorporate both the nervous system and cardiovascular system working together. The nervous system is connected through a series of vessels throughout the human body. The circulatory system is one of the bodies most important mechanisms that helps carry and transport nutrients and oxygen through blood circulation to help digest foods, fight off diseases, and keep the body at homeostasis. The nervous system is basically an extended system of the brain. Every action that the brain thinks, relays it through the nervous system to the specific body part to perform that action. Nerves send information from and to the brain to help regulate and operate organs and muscles in the body. Now how these two systems operate together can be described and explained through information about the baroreceptor reflex and diving reflex. The baroreceptor reflex is a homeostatic mechanism in the body which helps regulate a st able blood pressure. The way that the baroreceptor reflex works is that it provides a negative feedback loop so that when blood pressure increases, the reflex causes the heart rate to decrease in return decreasing blood pressure. When there is increased blood pressure, the carotid arteries and aorta stretches causing the baroreceptor reflex to increase it’s action potential generation. These action potentials are sent to the medulla oblongata through nerves in the body, and as a result,Show MoreRelatedChanges Of The Cardiac System1932 Words   |  8 Pagessystolic pressure is added to two thirds of the diastolic pressure. This gives us an accurate measurement of how much cardiac output by total peripheral resistance there is at one point and time. The mean arterial pressure is then monitored by baroreceptors that act to control blood volume, heart rate, stroke volume, and blood flow due to diameter of arterioles and veins (Sherwood, 374-380). The cardiac systems have many differing measurements to ensure proper function and response to situations

Paganism In Christianity Essay - 3102 Words

Religions across the globe have their own distinctive rites and rituals, idols, traditions, and values. Each have in common a desire to explain something unexplainable by common wisdom, or attributing some aspect of life to some higher power. Many religions have at their heart etiological stories, which explain some sort of natural phenomenon through the physical manifestation of their deity or deities. From high winds and thunderstorms to love, fertility, and the sun, such religions focus on the physical world in this life. Other religions try to explain the quot;nextquot; life or the afterlife. These religions usually give a moral code to live by, with stricter adherence to this code offering a better afterlife.†¦show more content†¦They, too, had their heavens and hells, deities and demi-gods. In short, each religion differs somewhat, but they all have similarities as well. Many stories in several classical religions share common themes or events. There are a great many similarities between stories of Babylonian, Greek, and Christian origin. An example of a shared event would be quot;the floodquot; story. Each of these religions tries to explain the reason of a severe flood, which historians have found actually occurred in their shared region. Christianity eventually replaced the quot;oldquot; religions, mostly by means of the spread of the Holy Roman Empire. There were many who opposed being converted, but after the remaining members of these religions realized that failure to convert meant you were a heretic, which meant death, the job of converting was much easier. Even then, some people did not want others telling them how to worship. They had their rituals and customs-they didnt want new ones. This sentiment was conveyed to the leaders of the Roman Churches, who quot;bentquot; their rules and procedures to fit these pagan rites and rituals. A good way to convert someone is to make him or her feel like its the same religion.

An artist†(6) he claims. His living conditions are horrible; he studies in a school with a lack of resources. He considered the different aspects of moving to Reardan, he struggled about leaving the Rez. In the end Junior decided to leave the Rez and make a better life for himself. He must go somewhere else, somewhere that people have hope. In order to get a decent education he made the difficult decision to transfer to the privileged white school in the town of Reardan. Leaving the Rez for a better life had a negative impact on Junior’s relationship with Rowdy. Junior and Rowdy were friends for a long time. â€Å"He is my best human friend and he cares about me† (16), â€Å"Rowdy has protected me since we were born† (17). Rowdy was the most important person in Junior’s life. By leaving the Rez, Junior lost his friend. When Junior told Rowdy about leaving the Rez he got mad, he hauls off and punched Junior in the face and told him, â€Å"Don’t touch me, you retarded fag† (52). Rowdy was angry with Junior; he thought Junior betrayed him by making this decision. Junior was upset about what happened he felt guilty that their relationship was ruined. â€Å"I knew that my best friend had become my worst enemy†(53). In sum, Junior lost his best friend Rowdy because of the decision that he made for a better life. In addition to losing his old friend making new friends at Reardan was hard and slow. When Junior arrived in Reardan he was scared. He didn’t know what was going to happen with the other students. He was wondering what he was doing in a racist white school. Did you know that Indians are living proof that niggers fuck buffalo? I felt that Roger had kicked me in the face. That was the most racist thing I ‘d ever heard in my life† (64) He tried to protect himself when he hit Roger, and he didn’t understand why Roger didn’t try to hit him back. He was scared about the decision that he made. Arnold was the center of attention and this feeling made him uncomfortable, â€Å"They stared at me like I was B igfoot or a UFO† (56). Most of the students rejected him, they called him names like â€Å"Chief† â€Å"Squaw Boy† â€Å"Tonto†Ã¢â‚¬ ¦ (64). It was the loneliest time of his life; â€Å" I just walked from class to class alone; I sat at launch alone; during PE I stood in the corner of the gym and played catch with myself† (83). He thought that he could make friends, but Reardan students didn’t want him in their school. He felt really lonely. As a result, Arnold was lost because everything in Reardan was different from the Rez; he knew that it would be hard for him to find his place in the racist school of Reardan. Although he had a lot of external problems with his new life style in Reardan, it was nothing compared to the internal conflict he suffered. Toward the end of the novel Junior was faced with an abundance of death among his family and friends. After the death of his grandmother, sister and his father’s best friend he was sad, and felt that all the bad things that happened to his friend and family were his fault. As a result he felt helpless and stupid: â€Å"I was mad at God† (171). â€Å"I was so depressed that I thought about dropping out of Reardan. I thought about going back to Wellpinit. I blamed myself for all of the death. I had cursed my family. I had left the tribe, and had broken something inside all of us, and I was now being punished for that† (173). He carried the guilt of his sister’s death; â€Å"I had killed my sister. Well, I hadn’t killed her. But she only got married so quickly and left the Rez because I had left the Rez first. She had burned to death because I had decided that I wanted to spend my life with white people. It was all my fault† (211). He took on the burden of responsibility for the death of his sister; she was killed in an accident when she was drunk; what happened to her wasn’t Junior’s fault. As result, he was terrified of losing his father, â€Å"Please God, please don’t kill my daddy† (203). Then Junior got some guidance from his father and some words of encouragement from his mother, and Junior began to understand that he made the change in his life for the better. Junior wasn’t the reason her sister died, but he had inspired her to follow her dreams as well. The upshot of all this is that, Junior’s decision about leaving the Rez and moving to Reardan for a better education was tough. He faced lot of problems; he felt lonely because of losing his best friend, and afraid of death of his tribe and family. Although he suffered from the entire bad things that happened to him, it was the best decision that he had made for his life. â€Å"I realized that I might be a lonely Indian boy, but I was not alone in my loneliness. There were millions of other Americans who had left their birthplaces in search of a dream† (217). Work cited Alexie, Sherman. The Absolutely True Diary of a Part-Time Indian.

Sad Daughter free essay sample

Both Polonius and the speaker from â€Å"To A Sad Daughter† are struggling with the concept of letting go of their daughter and both love their daughter. Polonius is not ready to let go of his daughter. As no mention has been made of Ophelia’s mother; we must assume that Ophelia is the predominant female figure for him in his life. He looks at Laertes as his heir, typical in his time, also evidenced by the fact that it seems that they have talked about Ophelia and Halmet’s relationship. He looks after his daughter and cares for her in his own ways. Although his bawdy advices to Ophelia when he asks her about her and Hamlet’s relationship may seem harsh, it may also be taken as a sign that Polonius is not ready to let go of his daughter. Every parent struggles to let their kids gain their independence but Polonius has not yet realized that his daughter is ready to have a relationship with some male other than her family members. We will write a custom essay sample on Sad Daughter or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page He not only fears that Ophelia might ruin her reputation and therefore ruin the family’s reputation, he also fears that if he has to acknowledge that Hamlet has â€Å"My lord, he hath importuned me with love/ In honourable fashion† as Ophelia claims then he must let go of Ophelia and trust someone else will take care of her as he and Laertes have tried to do. Polonius not letting his daughter take risks, although selfish at times, shows that he doesn’t want his daughter to do something she regrets, and thinks to take care of her so she doesn’t have to be burdened and he refuses to acknowledge that she can take care of herself because she seems to be the â€Å"baby† of the family. Meanwhile the speaker in â€Å"To A Sad Daughter† although he acknowledges that he is sad to let his daughter go, he actually will. Another gender role is shown in the first few lines of the first stanza where the reader actually thinks that he is talking about a son because of the reference to the pre-dominantly male sport of hockey. However, soon we learn that she is his daughter. The speaker, like Polonius, gives his daughter advice on life. Shocked that she is not taking risks in her life he is telling her to go out an be tempted by the sirens, which seems odd as sirens represent death. Polonius who is not even ready to acknowledge his daughter can make decisions for herself is way different from the speaker who thinks that if she never takes risks she will never life to its fullest. Because he loves her so much, the speaker knows that he must let her off to the world and trust that she will come back to him.
