Talk:Respiration (physiology)

Untitled

Theoretically this page could dichotomize by species (humans, fish, etc...), but I think most of this info is already just for humans so i will leave it.

I have added "breathing" in parantheses to the opening paragraph. As a layman, this does seem to be what we would say in the vernacular. Please revert this change if I have completely misunderstood this topic. -- dpol 07:00, 13 Apr 2004 (UTC)

Good work!

I really love this page and it's linked pages. And I look forward to the norwegian translations. --Ekko 08:35, 20 Feb 2005 (UTC) lol

Removing the merge, please

What do you think, everyone? How about making the respiration page about Aerobic and Anaerobic Respiration, (about internal, or cellular respiration) and removing the whole merge thing. --eshcorp

I agree. Respiration is by no means the same as respiration, so please remove merge.

Ditto and removing merge. Cburnett 05:04, 21 May 2006 (UTC)

Signalling agreement with this decision. User:Ceyockey (talk to me) 14:08, 21 May 2006 (UTC)

Total rewrite - definition of respiration

The name of this page is Respiration (physiology), but the existing page is not a physiological definition, it's a biochemical definition. Nearly all the content is already presented at cellular respiration. I have rewritten the bulk of the article to properly reflect the term's use in animal/human physiology. I removed a good deal of content, and have moved it here:

Respiration is the process by which an organism obtains energy by reacting oxygen with glucose to give water, carbon dioxide and ATP (energy). Respiration takes place on a cellular level where as breathing is on a different level. Respiration takes place in the mitochondrial membrane complex of eukaryotes and on the cell membrane of prokaryotes and provides the cells with energy.

Respiration also takes place in plants, where during the night they respire the products of photosynthesis - oxygen and glucose - to give energy, water and carbon dioxide.

Reaction of respiration

Aerobic respiration

Aerobic respiration requires oxygen in order to generate energy. It is the preferred method of pyruvate breakdown from glycolysis and requires that pyruvate enter the mitochondrion to be fully oxidized by the Krebs cycle. The product of this process is energy in the form of adenosine triphosphate (ATP), by substrate-level phosphorylation, reduced nicotinamide adenine dinucleotide (NADH) and reduced flavin adenine dinucleotide (FADH₂).

The chemical equation for glucose is: Ŗ C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy released (2830 kJ mol⁻¹)

Anaerobic respiration

Anaerobic respiration (also known as fermentation) refers to the oxidation of molecules in the absence of oxygen to produce energy. These processes require another electron acceptor to replace oxygen. Anaerobic respiration is often used interchangeably with fermentation, especially when the glycolytic pathway exists in the cell. However, certain anaerobic prokaryotes generate all of their ATP using an electron transport system and ATP synthase.

The chemical equation is:

C₆H₁₂O₆ → C₂H₅OH + Energy released (120 kJ mol⁻¹)

Anaerobic respiration releases much less energy than aerobic respiration because the alcohol released through anaerobic respiration still contains a great deal of energy.

Merge from External respiration

I suggested this merge, as it appears that the content of the above page merely covers the stage of pulmonary gas exchange and does not yet have enough breadth to merit its own article. Your views are appreciated. Robin S 01:02, 16 June 2007 (UTC)

I am really confused I really need help why don't you explain it more straight forward all I need is the tale of respiration it is very confusing —Preceding unsigned comment added by 92.9.44.232 (talk) 17:53, 27 January 2009 (UTC)

Misplaced text

I moved the following text to here, because it seems a bit off topic. Please sort the text out that specifically deals with respiration, or at least relate it more clearly. Mikael Häggström (talk) 05:43, 1 May 2010 (UTC)

'Disorders and Diseases of the Respiratory System' Nasal Catarrh is a very common complaint in this country, particularly in cold, damp weather. It manifests itself by excessive mucus secreting through the nose and sneezing. It is often the prelude to or accompanies other diseases. The Common Cold is the result usually of a virus infection and should be. distinguished from a chill, though the latter may provide suitable conditions for the virus to thrive and a cold easily follows a chill. Its extreme ineffectiveness is due to the viruses being transmitted through the air by sneezing. This is known as droplet infection. Catarrh accompanies the cold and this may pass to the throat and along the Eustachian tubes to the middle ear causing earache. If the infection continues further along the bronchial tubes into the lungs, bronchitis may set in. Bronchitis is one of the commonest of diseases in this country and is due to inflammation of the mucous membrane of the bronchial tubes. Laryngitis and pharyngitis are inflammations of the mucous membranes of the larynx and pharynx respectively. They may be preceded by catarrh and both the breathing and the voice are affected in laryngitis while pharyngitis is what we normally call sore throat. Tonsillitis is inflammation of the tonsils and the pharynx can also be affected. The tonsils become enlarged and pain is experienced when swallowing. The cause is usually bacterial infection. Whooping Cough is a common disease of children caused by bacterial infection. The "whoop" which gives it its name is during inspiration. Diphtheria is a very infectious disease, caused by a bacterium, Corynebacteriwn diphtheriae, which starts with an inflammation of the throat. Other symptoms follow and if anti-diphtheritic serum is not administered, post-diphtheritic paralysis may follow. This is not permanent but it takes time for recovery. The well-known Schick test is used to ascertain whether people are subject to the disease and immunization against it is now practiced. Croup occurs when the entrance to the larynx is swollen and constricted and breathing is therefore affected. Asthma attacks may be brought on by a number of agents such as pollen from grasses or by house dust, feathers, the fur of cats or dogs' hair to which these sufferers are allergic. Breathing is extremely difficult owing to constriction of the bronchial tubes. Hay Fever occurs in people whose mucous membranes are extremely sensitive to the pollen of grasses and therefore occurs only during the Summer. Considerable nasal discharge and the usual symptoms of the common cold develop. Antihistamines are often effective in relieving the symptoms. People subject to hay fever should obviously avoid being in a grass field. Pneumonia, of which there are several forms, is an inflammation of the lung tissues and the commonest form is caused by a bacterium, pneumococcus. High temperature, rapid, shallow breathing accompanied by cough and pain in the chest are symptoms. The coughing results in the expectoration of a thick, brown fluid. Sulphonamide drugs and antibiotic treatment are now used with effect. Pneumonia is now often produced by virus infection. Pleurisy is inflammation of the pleurae and may result from pneumonia and other more serious diseases such as tuberculosis. Empyema is a disease in which pus collects in the pleural cavity. This, too, may follow pneumonia and it may be necessary to resort to surgical means to drain off the pus. Silicosis is a hazard of workers in industries in which considerable amounts of silica dust are inhaled into the lungs. Pulmonary tuberculosis or phthisis, commonly called consumption, is caused by Bacillus tuberculosis (Mycobacterium tuberculosis). Once regarded as incurable it inevitably led to death but modern methods of therapy have completely changed the picture. The disease is extremely infectious and may easily be caught from the sputum of an infected person in which enormous numbers of the bacteria live and which get into the air by coughing or into the dust of the air from dried sputum. It may also be acquired from infected milk but the bovine bacillus affects children more than adults. Milk must therefore be adequately protected by pasteurization. Receptacles used by infected persons must on no account be used by healthy people. The name of the disease is derived from the fact that tubercles develop in the lungs, thus tending to obliterate the alveoli. Later these coalesce and the mass breaks down and the particles are discharged in the sputum. As a result cavities develop in the lungs. The disease is now curable and the mortality rate from it has fallen enormously in the last few years. In 1957, 4,784 people died of pulmonary tuberculosis, but by 1960 the number had dropped to 2,354, a decrease of about 50 per cent. Lung cancer, unlike pulmonary tuberculosis and like other forms of cancer, has been showing a marked increase in mortality rate in recent years. A cancer or carcinoma is a malignant neoplasm, a non-malignant neoplasm being a tumour. Although a cancer may be removed surgically, there is always the danger that the cells may be carried by the blood to other parts of the body where they initiate further cancerous growths. Cancer accounted for 122,648 deaths in 1966 in this country, an increase of 15,500 in ten years, and of these 30,483 were due to lung cancer, an increase of 9,000 over the same period. It has been proved that a minute quantity of carcinogenic (cancer producing) agents are present in cigarette smoke. The incidence of lung cancer has been shown to increase in proportion to the number of cigarettes smoked and as most cigarette smokers inhale, these dangerous substances get into the lungs. The death rate amongst cigarette smokers from lung cancer in this country is three or four times that among pipe smokers and about ten times that among cigar smokers*. Pipe and cigar smoking is therefore very much safer but in non-smokers the death rate from this disease is only about a thirteenth of those among cigarette smokers. These facts speak for themselves. Couple them with the knowledge that of the 615,719 deaths from natural causes in Great Britain in 1966 over 30,000 were due to lung cancer and you cannot fail to see that the matter calls for serious consideration. The morals to be drawn from these facts: do not inhale tobacco smoke into the lungs, smoke a pipe or cigars in preference to cigarettes or, better still, do not smoke at all. Cancer is a disease which has been known to man for a very long time but the number of deaths caused by it have increased out of all proportion to the increase in the population. In this disease cells multiply in a most disorderly and uncontrolled fashion forming malignant growths to the detriment of the normal tissue in which they are growing. Furthermore they can give rise to further cancerous growths in other parts of the body. The cause remains unknown at present and though a cancer virus has been discovered in monkeys, there is no evidence as yet that such is the case in man. Apart from surgery, radiotherapy with radium and X-rays have been used in the treatment of cancer but cobalt-ray treatment now largely supersedes them. Radium was first isolated by M. and Mdme. Curie in 1898 and radioactivity was discovered by Antoine Becquerel in 1890. A German physicist, Wilhelm Rontgen, was the discoverer of X-rays and these are not only used in treatment but also, of course, in diagnosis.

Garbage.

Both physiological and cellular respiration REQUIRE OXYGEN ?!?!? This is just not true. Nor does the definition of physiological respiration adequately include the importance of transport of the Redox metabolites to the cell (or transport IN the cell for that matter). I will leave it to those more skilled in the science to define the difference between physiological, cellular (and perhaps biochemical) respiration (cycles). This article is not up to Wikipedia's normal standards.71.31.147.72 (talk) 06:31, 11 December 2011 (UTC)

Proposed merge with Respiratory physiology

No need for second page Iztwoz (talk) 12:18, 21 May 2017 (UTC)

They are both rudimentary and contain similar content (very little), so I don't see any reason for keeping both. One thing which can be dropped is the statement that the topic is a branch of human physiology, as respiration an aspect of all physiology. Which title do you propose? • • • Peter (Southwood) ^(talk): 17:00, 31 May 2017 (UTC)

Hello Peter (Southwood) thanks for your response. Would prefer Respiration (physiology) - seems more apt and it's on Respiration dab page. Best --Iztwoz (talk) 19:58, 31 May 2017 (UTC)

I don't have any strong opinions on the more appropriate title at this point. Someone else may have a stronger argument one way or the other. If not, I will go with the flow. Are you planning to expand the resulting article? The current pair are in dire need of work, and it is not my field. • • • Peter (Southwood) ^(talk): 20:13, 31 May 2017 (UTC)

I was just spurred to merge proposal since the pages were just saying the same thing in essence. I've been looking at the pages and am of the opinion that the resulting page be further merged into Respiratory system as there is a large section on the physiology there already containing most of the info on these pages. --Iztwoz (talk) 20:21, 31 May 2017 (UTC)
