What is relationship between volume change and air flow in and out of lungs?

Sound (or speech ) is merrily a influx of vibration by the vocal cords that vibrate by exhaling the air through the throat ,so basically think of it like this "you blow a ballon ,but you don't tie it instead you pull the sides causeing a sound that sounds like flapping ,the more air you blew into ballon the longer it will make the sound ,Now let's blow it up and tie it and pop it with a needle ,it's much louder isn't it ? " try breathing in and talking and see for yourself :p

What is the relationship between the spine and the lungs?
the spine is lateral to the lungs
What volume change occur when we breath?
Your lungs expand when you inhale.
What is the relationship between expiration and larynx?
Sound is generated in the larynx, and that is where pitch and volume are manipulated. The strength of expiration from the lungs also contributes to loudness, and is necessary for the vocal folds to produce speech .
What does breathing have to do with the muscular system?
The muscles of the chest wall & the diaphragm change the volume of the chest ... thus the volume of the lungs, which is what breathing is.
What enables us to breathe?
The contraction of the diaphragm causes it to move down, increasing the volume of the thoracic cavity. This movement and volume change decrease the pressure in the lungs, and air rushes in.
What is the relationship between lungfish and amphibians?
The relationship between the lungfishes and amphibians is that the lung fishes have lungs unlike amphibians who don't because they depend on water
What are the strengths of the bell jar model of the lungs?
The bell jar model of the lungs is a simple representation that helps illustrate how changes in pressure impact lung volume and air flow. It is useful for conceptualizing basic principles of lung mechanics, such as inspiration and expiration. Additionally, it can assist in understanding the relationship between pressure differentials and lung expansion.
What is the relationship between the brain heart and lungs?
The heart and lungs work together to deliver oxygen to and remove carbon dioxide from the body's tissues. The brain uses this oxygen to function.
What muscle allows the lungs to fill the lungs with air?
The diaphragm. (located beneath the lungs) When it contracts it moves down, thus expanding the volume of the lungs. This causes the pressure in the lungs to decrease and air to flow in to the lungs. (pressure is inversely proportional volume- Boyle's law) This is inhaling. When the diaphragm relaxes it moves back up, decreasing the volume of the lungs and increasing the pressure which forces the air out. This is exhalation.
What is the relationship between the lung and the head?
The head contains the input organs (nose, mouth) through which air is supplied to the lungs through the trachea.
When does the lung relax?
The lung doesn't relax, it is controlled by the diaphragm When it relaxes the volume of the lungs decrease during expiration When it contracts the volume of the lungs increases during inhilation
Why is there always a residual volume left in the lungs?
there is always air left in the lungs because it needs the oxygen foe the lungs to inflate and deflate
