What's the difference between osphradium and respiration?
Osphradium
Definition:
(n.) The olfactory organ of some Mollusca. It is connected with the organ of respiration.
Example Sentences:

(10) Between the epithelial-supporting cells, the putative sensory elements consist of thin neurites (0.4-1.5 micron in diameter) that reach the sea-water side of the osphradium.
(11) The osphradium of Aplysia californica, a sensory organ, is a small yellow-brown epithelial patch located in the mantle cavity immediately anterior to the rostral attachment of the gill.
(12) Ciliary supporting and microvillous cells are described; they do not form any specific for the osphradium zones on its surface.
(13) Perfusion of osphradium of A. brasiliana with dilute seawater (95-80%) did not affect electrical activity of the bursting neuron R15; perfusion with 70 and 60% seawater caused a transient increase in the duration of the quiescent period.
(14) Chemoreceptors are commonly associated with the oral area, the tentacles, and the osphradium, which lies in the mantle cavity.
Respiration
Definition:
(n.) The act of respiring or breathing again, or catching one's breath.
(n.) Relief from toil or suffering: rest.
(n.) Interval; intermission.
(n.) The act of resping or breathing; the act of taking in and giving out air; the aggregate of those processes bu which oxygen is introduced into the system, and carbon dioxide, or carbonic acid, removed.
Example Sentences:
(1) This paper discusses the typical echocardiographic patterns of a variety of important conditions concerning the mitral valve, the left ventricle, the interatrial and interventricular septum as well as the influence of respiration on the performance of echocardiograms.
(2) Four cytotoxic antibiotics, bikaverin, duclauxine, PSX-1 and vermiculine, were examined with respect to their interference with glycolysis and respiration and their possible ionophoric or cytolytic activity.
(3) They are best explained by interactions between central sympathetic activity, brainstem control of respiration and vasomotor activity, reflexes arising from around and within the respiratory tract, and the matching of ventilation to perfusion in the lungs.
(4) Diphenoxylate-induced hypoxia was the major problem and was associated with slow or fast respirations, hypotonia or rigidity, cardiac arrest, and in 3 cases cerebral edema and death.
(5) The acute effect of alcohol manifested itself by decreasing mitochondrial respiration, compensated by increased glycolytic activity of the myocardium so that myocardial energy phosphate concentration remained unchanged.
(6) A relationship has been obtained experimentally to permit conversion of the counts to respirable mass concentrations.
(7) Studies with liver mitochondria prepared from lactating hexachlorophene-fed rats showed a 50-75% inhibition of respiration with succinate as substrate.
(8) and respirated with a pneumatic respiration pump and the parameters blood pressure, pH and blood gases (pO2, pCO2) were continuously recorded.
(9) The interactions of nitrous oxide with cytochrome c oxidase isolated from bovine heart muscle have been investigated in search of an explanation for the inhibition of mitochondrial respiration by the inhalation anesthetic.
(10) A sharp decrease in oxygen uptake occurred in Neurospora crassa cells that were transferred from 30 degrees C to 45 degrees C, and the respiration that resumed later at 45 degrees C was cyanide-insensitive.
(11) The degree of venous congestion in the lungs of patients with mitral stenosis varies with the phases of respiration.
(12) In this study, at first, the states of sleep and wakefulness in newborn infants (measured simultaneously by EEG, EOG, respiration and body movement) were compared with their heart rate patterns in rest, active, awake and unclassified phases.
(13) In this study we propose a method for the analysis of the relationship between heart rate changes and respiration as a possible diagnostic tool for cardiac autonomic damage.
(14) Respiration-related neurons were classified with respect to the correlation of their activity with the activity of the phrenic nerve: phase-bound inspiratory (I) and expiratory (E) neurones and phase-spanning expiratory-inspiratory and inspiratory-expiratory neurones were discriminated.
(15) Tests included recording the scalp EEG, visual and auditory cerebral evoked-potentials, the CNV, cerebral slow potentials related to certainty of response correctness in auditory discrimination tasks, heart rate, respiration and the galvanic skin response.
(16) The excited group had significantly lower pH, pCO2, and base excess values, but significantly higher pO2 values, rectal temperatures, and pulse and respiration rates.
(17) The experience of reflexotherapy of 86 patients showed its positive effect on the psychoemotional activities of patients with obesity, a rise of adaptation capabilities of the body under physical exercise, improved external respiration function, an increase in oxygen saturation of tissues, the stimulation of metabolism (by the basal metabolism findings) by way of increasing the secretion of hypophyseal tropic hormones, triiodothyronine and thyroxin, and potentiation of the time course of loss of body mass.
(18) Chemical control of respiration becomes less stable during the light stage of sleep, despite a reduction in chemoresponsiveness, due to a concomitant increase in "plant gain" (i.e., responsiveness of blood gases to ventilatory changes).
(19) It is supposed that the stimulating effect of lactate with NAD+ on the mitochondria respiration is not so much a result of the membrane-damaged action as a result of oxidation of lactate dehydrogenase reaction products: phosphorylative oxidation of pyruvate and nonconjugated oxidation of NADH.
(20) It is suggested that the presence of abnormal OORR in sleep apnea may reflect a basic defect in pontomedullary control of respiration during sleep.
