a conjunction of nerves”,explainsCristopher Kopplinof theUniversity of Bayreuth. "There is a phenomenon called sinus node arrhythmia, where exhalation increases parasympathetic activity, and consequently, lowers heart rate and makes us calm down. Deep, slow, and rhythmic breaths maximize this effect....
During NREM (the phase of sleep in which there is no rapid eye movement) breathing becomes deeper and more regular, but there is also a decrease in the breathing rate, resulting in less air being exchanged overall. This occurs because during NREM sleep the automatic, metabolic system has ...
CONTROL OF BREATHING Automatic and Voluntary Mechanisms Control of respiratory muscle activity arises from within the central nervous system. The rate and depth of respiration are regulated by two control systems—the automatic and the voluntary mechanisms—that usually interact with each other (Fig. 2...

但原句整个都是一个例子，往前看。前一句仍然在说肌肉relax的事情，因此也是例子，所以看开头，开头说air passage在睡觉期间变了很多紧接着就解释睡觉期间呼吸很难，也就是开头所指的变化是睡觉的时候呼吸变难，所以正确答案是C。A的refute与原文相反；B的比较和D的prevent blockage原文都没说 ...
In human lungs, gas exchange occurs at the ___. a. bronchi b. pericardium c. alveoli d. epiglottis What is the relationship between the area of the respiratory surface and the rate of gas exchange? What are the factors that affect the breathing rate of human beings? What is the amount...
Recent studies have established that cardiac and respiratory phases can modulate perception and related neural dynamics. While heart rate and respiratory sinus arrhythmia possibly affect interoception biomarkers, such as heartbeat-evoked potentials, the
This rate is encouraged by many wisdom traditions via prayer, chanting, and other contemplative practices that slow the breath. breathe lightly, silently and subtly. Loud breathing is stress breathing and signals danger to our nervous system. A subtle breath invites a perception of safety. breathe...
from Chapter 3 / Lesson 15 66K Breathing rate, or respiratory rate, is an individual's number of breaths per minute. Learn the definition and calculation of breathing rate and discover the mechanism of breathing rate regulation. Related to this QuestionWhat...
Lung cancer is the leading cause of cancer-related deaths worldwide, with a 5-year survival rate of <15% [98]. Lung cancer is a highly heterogenous disease that can be classified into four histopathological subtypes. Approximately 15% percent of lung cancer cases are classified as small cell...
