during inspiration, intrathoracic pressure is decreased.
There is no evidence that low frequency sounds affect the heart.
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.

Respiration and heart rates change greatly during physical activity. How much they fluctuate can depend on the intensity and duration of the workout. Respiration and heart rate will double at times during an exercise routine.
true. Heart sounds or lubb dubb are created when the valves of the heart snap shut
There is no evidence that low frequency sounds affect the heart.
Pesticides have adverse effect on photosynthesis and respiration on host pants.
Alcohol has a negative effect on the heart rate and thinking, perhaps also respiration. It makes the body and mind react slower. E.g if you have an overdose of alcohol your mind will lose control of your body and you can even have a nervous breakdown. Your heart will pump blood around much slower. This results in unclear thinking. As for respiration I don't know for sure but I think your body will respirate much less due.
effect of high frequency sounds
Temperature and respiration are usually unaffected; however, heart rate and blood pressure may be affected depending on the type of condition involved (rheumatic, pericarditis, etc).
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.

Understanding Pediatric Heart Sounds was created in 2003.
Two sounds
Amphibians have three-chambered heart and lungs for respiration, while fishes have two-chambered heart and gills for respiration.
Understanding Pediatric Heart Sounds has 237 pages.
