Not vegetative spiration, it is not surely (which plants have) that in this life should be so dear unto us; nor sensitive respiration, the proper life of beasts, both tame and wild; nor this our imaginative faculty; nor that we are subject to be led and carried up and down by the strength of our sensual appetites; or that we can gather, and live together; or that we can feed: for that in effect is no better, than that we can void the excrements of our food.
Physiologists believe that the brain must be bathed by warm blood to be highly active, and this requires aerial respiration; so that warm-blooded mammals when inhabiting the water lie under a disadvantage in having to come continually to the surface to breathe.
All physiologists admit that the swim-bladder is homologous, or "ideally similar" in position and structure with the lungs of the higher vertebrate animals: hence there is no reason to doubt that the swim-bladder has actually been converted into lungs, or an organ used exclusively for respiration.
But it is conceivable that the now utterly lost branchiae might have been gradually worked in by natural selection for some distinct purpose: for instance, Landois has shown that the wings of insects are developed from the trachea; it is therefore highly probable that in this great class organs which once served for respiration have been actually converted into organs for flight.
These cirripedes have no branchiae, the whole surface of the body and of the sack, together with the small frena, serving for respiration.
Therefore it need not be doubted that the two little folds of skin, which originally served as ovigerous frena, but which, likewise, very slightly aided in the act of respiration, have been gradually converted by natural selection into branchiae, simply through an increase in their size and the obliteration of their adhesive glands.
Miss Murdstone, by an expressive sound, a long drawn respiration, which was neither a sigh nor a moan, but was like both, gave it as her opinion that he should have done this at first.
But the bird has a voice, and with plaintive cries will make known her fear; but the fear of this vast dumb brute of the sea, was chained up and enchanted in him; he had no voice, save that choking respiration through his spiracle, and this made the sight of him unspeakably pitiable; while still, in his amazing bulk, portcullis jaw, and omnipotent tail, there was enough to appal the stoutest man who so pitied.
Besides, if you regard him very closely, and time him with your watch, you will find that when unmolested, there is an undeviating rhyme between the periods of his jets and the ordinary periods of respiration.
One study explained the success by increasing the intensity of the training (due to increased heart and respiration rate).
In this situation, impaired cellular respiration leads to lower pH levels.
Gull records that she had suffered from amenorrhoea for nearly a year, but that otherwise her physical condition was mostly normal, with healthy respiration and heart sounds and pulse; no vomiting nor diarrhoea; clean tongue and normal urine.
Gull was struck by the similarity of the case to that of Miss A, even to the detail of the pulse and respiration observations.
He records that she displayed no sign of organic disease; her respiration was 12 to 14; her pulse was 46; and her temperature was 97 °F. Her urine was normal. Her weight was 4 stone 7 pounds (63 pounds) and her height was 5 feet 4 inches.
Gull observed that slow pulse and respiration seemed to be common factors in all the cases he had observed.
Sometimes the bacterial species are highly specialized for organochlorine respiration and even a particular electron donor, as in the case of "Dehalococcoides" and "Dehalobacter".
One particularly important example for public health is the organochloride respiration of the dry-cleaning solvent, tetrachloroethylene (PCE), and the engine degreasing solvent trichloroethylene (TCE) by naturally occurring anaerobic bacteria, often members of the candidate genera "Dehalococcoides".
Primary production is distinguished as either "net" or "gross", the former accounting for losses to processes such as cellular respiration, the latter not.
Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").
Net primary production is the rate at which all the plants in an ecosystem produce net useful chemical energy; it is equal to the difference between the rate at which the plants in an ecosystem produce useful chemical energy (GPP) and the rate at which they use some of that energy during respiration.
Gross production is almost always harder to measure than net, because of respiration, which is a continuous and ongoing process that consumes some of the products of primary production (i.e. sugars) before they can be accurately measured.
Estimates of ecosystem respiration, the total carbon dioxide produced by the ecosystem, can also be made with gas flux measurements.
During night, this technique measures all components of ecosystem respiration.
This respiration is scaled to day-time values and further subtracted from NEE.
As photosynthesis has not taken place in the dark vessel, it provides a measure of ecosystem respiration.
The light vessel permits both photosynthesis and respiration, so provides a measure of net photosynthesis (i.e. oxygen production via photosynthesis subtract oxygen consumption by respiration).
Gross primary production is best estimated using relatively short incubation times (1 hour or less), since the loss of incorporated 14C (by respiration and organic material excretion / exudation) will be more limited.
The methods based on stable isotopes and O2/Ar ratios have the advantage of providing estimates of respiration rates in the light without the need of incubations in the dark.
EMTs (Emergency Medical Technicians), in particular, are taught to measure the vital signs of: respiration, pulse, skin, pupils, and blood pressure as "the 5 vital signs" in a non-hospital setting.
Respiratory rate is clear indicator of acidotic states, as the main function of respiration is removal of CO2 leaving bicarbonate base in circulation.
Troxipide accelerates oxygen intake of marginal gastric mucosa and glycogen consumptive stimulation of the gastric mucosa of the corpus, thereby elevating the tissue respiration and energy metabolism.
The consumption of oxygen during the generation of reactive oxygen species has been termed the "respiratory burst", although unrelated to respiration or energy production.
A second doctor was called and the couple was admitted to Frimley Cottage Hospital. Chevis died at 1:00 am the following morning after five doctors had administered artificial respiration over a period of several hours, and he had been given powerful emetics.
"Aeromonas salmonicida" is a facultative anaerobe, which means it is capable of making ATP by aerobic respiration if oxygen is present, but is also capable of switching to fermentation when oxygen is not present.
Overstimulation of nicotinic acetylcholine receptors in the central nervous system, due to accumulation of ACh, results in anxiety, headache, convulsions, ataxia, depression of respiration and circulation, tremor, general weakness, and potentially coma.
Due to children's decreased size, faster rate of respiration, and continuing organ development, this area is important to research.
One of the immediate consequences of increased cellular respiration is a rise in the NADH and NADPH concentrations (collectively referred to as NAD(P)H).
Those who received alprazolam also had increased respiration rates (22.7 vs 18.3 breaths/min).
It uses crassulacean acid metabolism (CAM), where it stores some carbon dioxide produced by respiration at night and releases this for use in photosynthesis the next day, but the overall contribution of this is small compared to true CAM plants such as cacti.
In some individuals, the effect of oxygen on chronic obstructive pulmonary disease is to cause increased carbon dioxide retention, which may cause drowsiness, headaches, and in severe cases lack of respiration, which may lead to death.
In most species the spiracles are large and are the main means of drawing water in for respiration.
His chapter on respiration presaged the discovery of oxygen. Robinson's next work was a "Dissertation on the Food and Discharges of Human Bodies", 1747.
