Respiratory System - 1551 Words

RESPIRATORY SYSTEM The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory†¦show more content†¦The Diaphragm and Intercostal Muscles When you breathe in (inspiration), your muscles need to work to fill your lungs with air. The diaphragm, a large, sheet-like muscle which stretches across your chest under the ribcage, does much of this work . At rest, it is shaped like a dome curving up into your chest. When you breathe in, the diaphragm contracts and flattens out, expanding the space in your chest and drawing air into your lungs. Other muscles, including the muscles between your ribs (the intercostal muscles) also help by moving your ribcage in and out. Breathing out (expiration) does not normally require your muscles to work. This is because your lungs are very elastic, and when your muscles relax at the end of inspiration your lungs simply recoil back into their resting position, pushing the air out as they go. PHYSIOLOGY The diseases and disorders of the respiratory system can affect any part of the respiratory tract and range from trivial to life-threatening. The nasal passages and pharynx, for example, are targets for the viruses that cause colds. These viruses infiltrate and destroy the cells of the nasal passage membranes. The immune system fights back by increasing blood flow to the area, bringing numerous virus-attacking white blood cells to the scene; this causes the membranes to swell, resulting in the stuffy nose associated with colds.

The respiratory system is built up of the organs in our body that serve us to breathe. It offers the blood with oxygen in order for the blood to deliver oxygen to all parts of the physical structure.

Nursing Opportunities in NYU Downtown Hospital Free Essays

Nurses are indispensable members of the work force unit division in health care system whose main role is to provide for doctor’s assistance and cater to the health status and palliative care of the patients. Technically though, the nurses have higher specialized forms or masteral degrees which elevates them to a higher position in hospital departments (e.g. We will write a custom essay sample on Nursing Opportunities in NYU Downtown Hospital or any similar topic only for you Order Now perioperative nurse). The NYU Downtown Hospital is the only hospital in Manhattan that caters to the healthcare of the Lower Manhattan Community specifically that of the Chinese community. The hospital employs wide and diverse medical professionals to provide for quality healthcare of the community and amongst the members of the workforce are the nurses. In NYU Downtown, the hospital’s selection of nurses for a specific job requires a basic New York Registered Nurse qualification and related experiences. The nursing opportunities for the hospital vary from jobs descriptive of leadership, staffs and per diem positions. Vacancies in leadership positions are on the following types: Nurse Manager for the peri-operative division, clinical nurse specialist in the Maternal Child Health Division, Nursing Administrative Supervisors for morning and evening shifts, and Registered Nurse Case Manager. For the staff positions, there are vacancies in the following departments and the corresponding time table: Emergency Room, Operating Room and Labor and Delivery for 12 hr duty day or night and Licensed Practical Nurses (LPNs) positions for 7.5 hr per day. Per diems are available for all units in the hospital on all shifts. The workplace is suitable for nurse employment because aside from sufficient wages and benefits, the hospital meets the standards of the healthcare system in terms of management and services rendered. The salary of registered nurses in the district is $53, 065 as of 2002 with an annual increase rate of 1% per year. Benefits include health,   dental , liability insurance, disability and   compensation programs, refunds and   annuity plans. Subsidies for houses, parkings and discounts are also available for employees. NYU Downtown Hospital’s vacancies for nursing positions mirror one of the stigmas of the New York medical profession nowadays — nursing shortage. As previously mentioned the singularity of the hospital in the area implies a huge demand for medical practitioners including the nurses. Unfortunately, in the entire New York, the supply of nurses does not meet the high rate of nurse demand. Although there are more than 234,000 Registered Nurses and 68,900 LPNs in 2001, the prediction for nurse sustainability is bad since there was an overall drop for the 1999 to 2001. Slow growth rate for Registered Nurses may indicate problems for the quality healthcare and     according to he National Sample Survey of registered Nurses, the state ranked second to the last in terms of RN percentage employment. The nursing shortage in New York are caused by several factors: aging workforce, increased job opportunities for women, low wages and benefits and other related factors which caused a decreased in the supply. Manhattan’s Downtown Hospital is aggravated, because as the lone hospital they must cater to both the resident and the non-resident community. (Non-residents are approximated at almost 400,000 per day.) The general trend for nursing shortage creates opportunities for work in the nursing arena in the New York Downtown Hospital. Although, the workplace and the salaries are sufficient enough for nursing occupation, NYU Downtown’s nursing problems may be fueled by a larger economic workforce crisis in the nursing arena.

Argumentative Essay on Teen Pregnancy free essay sample

Some people say that this is society’s fault. Although having sex and getting pregnant is due to personal choices and decisions, there are a few things society could do to prevent it. Excessive teenage pregnancy could be controlled with appropriate media, more readily available birth control, and people to set good examples for young women. Just flipping through the channels on a Saturday afternoon you can see all sorts of inappropriate media full of sexual suggestions. Even aside from all the sex scenes in movies, there are shows about teen pregnancy. Shows like Teen Mom and 16 and Pregnant make pregnancy seem acceptable and cool. If having sex at young ages didn’t seem like the cool thing to do, many teens wouldn’t do it. Taking inappropriate shows and movies off the air could make a difference in the teenage pregnancy rate. There are many forms of birth control. In a lot of arguments about teen pregnancy there is talk about making condoms more readily available, but I think that other forms of birth control that are more consistently effective should be promoted instead. We will write a custom essay sample on Argumentative Essay on Teen Pregnancy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Condoms are important to use, but many times they can break or be ineffective. Plus let’s face it, in the heat of the moment lack of a condom doesn’t always keep sex from happening. Birth control pills are a cheaply made, more effective form of birth control. If forms of birth control such as the pill were cheaper and easier to get, more teens would be protected and less would get pregnant. The world in general is in need of good role models. Anyone that tweens and teens look up to should really try to focus on setting a good example. In a world full of bad examples, its especially important to set good ones for the group of people in that developmental stage. Teenagers need role models to protect them from falling victim to the pressures of today’s society, especially the sexual ones. In conclusion, I believe that teenage pregnancy is a very important issue. The sexual society of today’s America has resulted in a large increase in teen pregnancy. Programs that promote teen pregnancy and things that lead to teen pregnancy should be taken off every day television. Although it is going to be impossible to keep teens from having sex, making birth control extremely easy to use and get ahold of could have a huge effect on the teenage pregnancy rate. These two things along with good parental guidance and support, and good role models to look up to, would keep most teens from getting pregnant.
