Is intrapulmonary pressure greater than or less than?
Yes, typically it is.
The volume of a sphere depends on its radius so the volume is a function of the radius. If this function is called Vr use the formula below to compute V4 the volume of a sphere with a radius of?
V(4) = 4/3, 64, pi
In the equation V equals πr 3 the volume of a sphere V is a function of R the spheres radius. What is the independent quantity in this function?
The volume of a sphere = 4/3*pi*radius3
What is Function of a pippet?
It is used to measure small volume of liquid to be added where needed .
Why is volume measured by cubic units?
because volume is a function of all three dimensions, length, width and Height. X, Y and Z
What happens to the intrapulmonary pressure when intrapulmonary volume increases?
Pressure increases as volume increases, granted the container stays the same.
What is the result of intrapulmonary volume increase?
inspirtation
What is the result of inspiration and expiration?
This occurs within the respiratory system. During inpiration, the intercostal muscles contract, the diaphragm descends, and the rib cage rises. The thoracic cavity volume increases, stretching the lungs, and the intrapulmonary volume increases. This causes the intrapulmonary pressure to drop. Air flows into the lungs until the intrapulmonary pressure equals the atmospheric pressure. During expiration the intercostal muscles relax, the diaphragm rises, and the rib cage descends. The thoracic cavity volume decreases, causing the the lungs to recoil, and the intrapulmonary volume decreases. This causes the intrapulmonary pressure to rise, and the air flows out of the lungs until the intrapulmonary pressure equals the atmospheric pressure.
Definition of intrapulmonary pressure?
Intrapulmonary pressure is the pressure within the air passage and the alveoli of the lungs.
When intrapulmonary pressure drops below atmospheric pressure what is able to occur?
Inspiration occurs when the intrapulmonary pressure decreases to below atmospheric pressure
What would occur when he atmosheric pressure is higher than intrapulmonary pressure?
When the atmospheric pressure is higher than intrapulmonary pressure pressure, inspiration will not take place.
What is the pressure inside the lungs called?
Intrapulmonary pressure
What is the difference between Intrapulmonary and Intrapleural?
Transpulmonary pressure
If your chest expands you would predict the intrapulmonary pressure to?
Decrease
Which is true about intrapulmonary pressure and intrapleural pressure?
Intrapulmonary pressure will equalize to atmospheric pressure during a breathing cycle, but intrapleural pressure should always be less than atmospheric pressure.
What is the function of residual volume?
The function of residual volume is to keep enough pressure in the lungs to keep them from collapsing.
When intrapulmonary pressure is above atmospheric pressure what is able to occur?
expiration
