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.
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
Respiration influences heart sounds primarily through changes in intrathoracic pressure, which affects venous return to the heart. During inspiration, the negative pressure increases venous return, often resulting in a slight increase in heart sounds due to enhanced blood flow. Conversely, during expiration, venous return decreases, which can lead to a reduction in the intensity of heart sounds. This respiratory variation is particularly notable in conditions like pericardial effusion, where heart sounds may become muffled and vary with respiration.
There is no evidence that low frequency sounds affect the heart.
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.
Pesticides have adverse effect on photosynthesis and respiration on host pants.
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.
