Excretory System free essay sample

The excretory system eliminates wastes from the body while also maintaining water and chemical balances. The main organs of the excretory system are the kidneys, the ureters, the bladder, the urethra, the skin, and the lungs. The main things that the body must excrete are nitrogen wastes and carbon dioxide. Nitrogen wastes are a byproduct of protein metabolism. Protein metabolism is the making of amino acids into proteins and the breaking-down of proteins into amino acids. Carbon dioxide is made when the lungs bring in oxygen and it is taken to cells for cellular respiration and as a byproduct carbon dioxide is made. Humans have two kidneys that are kind of bean shaped. The kidneys are located one behind the stomach, and the other behind the liver. Together they regulate the chemical composition of the blood. The kidneys are made up of a bunch of different part starting with the cortex on the outside.

(Towle, 1999) The inner two-thirds is called the medulla. The medulla consists of 6 to 18 triangle shaped renal pyramids the bigger parts of the pyramids is next to the cortex and the tips, or renal papilla poke into the renal sinus. Each of the pyramids have grooves that meet at the papilla. The pyramids are separated by a tissue called renal columns. The columns have a texture that is very similar to the cortex. A renal lobe is made up of a renal pyramid, its area of cortex, and its columns. Urine production happens in the renal lobes. The renal papilla have small ducts that shoot urine into small cup-shaped drains called the minor calyx. Four or five minor calyces make up the major calyces and two or three combines major calyces make up the renal pelvis. The renal pelvis is a large, funnel shaped chamber that is connected to the ureter which drains the kidney. (Martini, Nath. 2009) Nephrons are the functional units of the kidneys. Each kidney has more than a million nephrons, and if they were all stretched out they would go for fifty miles. Each of the nephrons has a cup-shaped structure called a Bowman’s capsule. The Bowman’s capsule encloses a bed of capillaries called a glomerulus. The glomerulus receives blood from the renal artery. High pressures force fluids from the blood through the capillary walls walls and into the Bowman’s capsule. The material that is filtered from the blood flows through the renal tubule ,â€Å"A long tube with permeable walls. † Blood that is still remaining in the glomerulus flows through a bunch of capillaries that wrap around the three parts of the renal tubule, the convoluted tubule, the loop of Henle, and the distal convoluted tubule. The long course of the renal tubule and the capillaries surrounding it make a very large surface area for the exchange of materials. (Towle, 1999)

Progress Essays - Copernican Revolution, Anglican Saints

Progress Essays - Copernican Revolution, Anglican Saints Progress Progress It started with pureness, then became sin. It didnt matter to people, they didnt follow. Ignorance, immorality, we just got worse. Until, one day He made a rainbow. It started all over again. Now people had to care. If they kept up their bad habits, they knew their future. So onward we went, our intelligence grew. Aristotle to Copernicus, I thought we were the center!? Then Kepler wrote Harmony of the Spheres. I didnt read it. Did you? But Newton it was who discovered Keplers three laws. How are things put in orbit? No one really cares. We keep getting smarter but does anyone notice? Its taken for granted, I think Ill live. Einstein arrived with his crazy ideas. I forgot, what are they again? Humans progressed to things they could never imagine. We landed on the moon, but do your remember when? Now were here with electronics and computers. Everything is digital. No one seems to care. Not many appreciate the progress that has led us here. But when will it start all over again? -James Hanson (Please use this poem only as a reference. Thanks.)

The Dangers of NaNoWriMo

The Dangers of NaNoWriMo The Dangers of NaNoWriMo This is the last week of one of the year’s most frenetic months for writers: National Novel Writing Month. Since its foundation in 1999, the now-universally-abbreviated NaNoWriMo has established itself as the best opportunity for aspiring writers to stop being just that.At the last New Generation Self-Publishing Summit (sponsored by Reedsy), Porter Anderson said something that really stuck with me (and apparently others – see tweets below): â€Å"‘E’ will obliterate territorial rights.†Exactly. ‘E’ has this extraordinary capacity to tear down physical or territorial barriers – and that’s true for everything from books to . In the case of NaNoWriMo, ‘e’ gives rise to a universal writers’ group where authors meet annually, exchange tips, support one another and update the community on their progress. The result is a global race where winning is accessible to everyone, because winning means finishing the ma nuscript. These kind of races always end up creating a strong sense of community.To the casual observer, NaNoWriMo might seem like the greatest thing to happen to writers since QWERTY. But the e-phenomenon might not be for everyone. Here’s why.1. The â€Å"New Year’s Resolution† EffectLet’s start with a mild accusation. To me, it sounds like â€Å"NaNoWriMo† is to authors what January is to non-authors: that time of year when you take on game-changing projects that you hold on to†¦ for a month.Writing over 1,000 words a day is something many authors do throughout the year (or at least several months a year), and many successful authors write in excess of 10,000 words per month. While NaNoWriMo creates the perfect incentive to *start* doing that, I think it is as important for authors to stick to the 1,667 words a day during NaNoWriMo as it is for them to keep writing regularly afterwards (at a slower pace, maybe). NaNo can create momentum, but it can also cause burnout for those unaccustomed to such a colossal creative effort.NaNo shouldn’t be the exception in an author’s life; it should be the ramp that launches a writing career.2. â€Å"In the end, it’s all about writing, you know?†There’s a Holy Trinity of generalized advice to authors out there that comes up regularly at conferences or in blog posts, forums and social media: 1. Writing is only half the job; reaching readers is the other half. 2. Writing your next book is your #1 marketing tool. 3. Present your book to readers only when it’s in the best possible shape.NaNoWriMo sets up authors to follow none of this advice.Think about it: You’re writing 1,667 words a day. You have a full-time job on the side. You spend the little spare time you have tweeting updates about your writing and contributing to a #nanowrimo hashtag feed that is already flooded by self-publishing companies trying to get participants’ att ention.In the meantime, not much is done for â€Å"the second half of the job† – marketing. It’s easy when all the focus is around #amwriting to forget about the occasional reader-directed tweet or Facebook post, the monthly newsletter, blogging, reader-mapping, etc. Not all authors forget about marketing during NaNo (the â€Å"big names† keep blogging heavily as a matter of fact), but there’s a certain detriment to everyone in the author community putting sole emphasis on â€Å"just writing† for a month.This brings us to item #3. Speed and precision are rarely bedfellows, and NaNo manuscripts are no exception. I’ll expand on this point below.3. â€Å"There! I’m done! Let’s publish now.†I’ve heard from several Reedsy editors that the months following Nano are usually super busy for them. Authors have their first drafts in hand and are so proud that they want to capitalise on the momentum and accelerate the â€Å"publishing process† so their book gets out there quickly. NaNoWriMo puts so much emphasis on speed that it invites authors to neglect the 3rd rule cited above, and accentuates an author’s biggest vice: impatience.Eagerness is perfectly understandable, especially in light of the massive effort it takes to write 50k words in 30 days. But that pace is challenging even for seasoned authors, and at best would result in a first draft – a starting point for editing and revision. Looking for an editor right after NaNo can be a good option, but only if you’re looking to get a quick manuscript assessment (most Reedsy editors offer that, and some will offer a discount in December/January for NaNo manuscripts). Doing a developmental edit, let alone a copyedit or proofread on your manuscript is a waste of time and money; you’re simply not ready – or at least, your NaNo manuscript isn’t.Even if you ARE the rare specimen ready for the next pha se of manuscript development come December 1, tens of thousands of other NaNoWriMo participants will be looking for a developmental editor during the same period of time. This means that all good, reputable editors are going to be fully booked for a couple of months. Have you ever tried finding a free treadmill at a gym in January? Well, it’s like that, but worse. Patience! Take December, or even January too, to edit your book, develop an early reader base (or look for beta-readers), pair up with other authors to prepare a common launch, or get started on your next book. Releasing several at a time can be an unexpected way to get noticed very quickly by the gremlins that power Amazon’s algorithms (aka, an indie author’s best friends*)†¦Like Christmas does for consumer capitalism, NaNoWriMo generates an incredible amount of enthusiasm and energy for creative writing. But it’s not without risk, and sometimes gives rise to misperceptions about what writ ing seriously involves. Impatience, burnout and neglect of the market are natural pitfalls for NaNo participants. So authors: tread carefully, and learn from your experienced peers. Use NaNoWriMo not as an end in itself, but as another tool in your kit. November comes but once a year, but writing your novel is a 24/7/365 commitment.*Next to self-doubt and caffeine, anyway.By Ricardo FayetEdited by the lovely Reedsy editor Becca Heyman–What do you personally think of NaNoWriMo? I’d love to know your thoughts on this so don’t hesitate to leave a comment!

Quantitative Research Article Critique Paper Example | Topics and Well Written Essays - 2000 words

Quantitative Article Critique - Research Paper Example Independent and Dependent Variables of the Study For this study, a set of independent variables were initially tested for statistically significant effect on the dependent variable; the dependent variable being the test-taker’s success or failure at first sitting in an NCLEX-RN examination. The independent variables initially tested included SAT / ACT scores, science grade point average (GPA) prior to admission to the nursing program, critical thinking test score, writing portfolio score, individual nursing course grades, number of nursing course failures, all standardized test scores, graduating GPA, and number of semesters taken to complete the nursing program (McGahee, Gramling, & Reid, 2010). Science GPA was taken from the participant’s anatomy, physiology, and chemistry courses; the standardized tests were made up of a critical thinking test, an end of course test for each nursing course, and an RN Assessment test designed to predict NCLEX-RN success; the regular n umber of semesters required to complete the nursing program after completion of general education courses and acceptance into the nursing program was five. ... However, it may be noted that these same variables were not given due operational definitions which resulted in a vague description of how data was quantified in order to represent these variables. Without proper operationalization of the variables, future researchers may have a difficulty replicating such a study (Coughlan, Cronin, & Ryan, 2007). There was not much information on the demographic structure of the participants for this study. Their only qualification was being a graduate of a baccalaureate nursing school over a period of three years between fall 2006 and spring 2009. No information was provided on the participants’ sex, age, race/ethnicity, or socio-economic status. In addition, relevant characteristics of the sampled baccalaureate school were not identified (McGahee, Gramling, & Reid, 2010). Research Design A retrospective correlation design was used for this particular investigation (McGahee, Gramling, & Reid, 2010). As this study looks into possible predicto rs of NCLEX-RN success, the sample was treated as a whole and the independent variables were simply tested on their predictiveness capability, looking into main effects, and interaction effects between and among predictors. One notable discrepancy of this study is that the predictors were not tested for collinearity with each other. Duffy (2005) points out that such a test is necessary in order to filter out the possible redundant effects of certain variables. On the plus side, this study was designed in a similar manner as a number of previous studies as identified in the Review of Literature section. The methodologies used for this study bears similarities with the previous studies except for the specific variables under
