When the frog opens its mouth, Air flows in because it's in the nature of gases to flow from high pressure to low pressure ( Air to mouth ). When the air is inside the mouth of the frog, it closes its nose trills ( to avoid the escape if any air trapped ) and closes its mouth. When nose and mouth are closed, the air is trapped inside the mouth. Then, the frog raises its jaw which presses the air inside the mouth towards the lungs, because again, air under higher pressure (in mouth) goes to a place where there's lower pressure ( the lungs ). This is positive pressure inhalation.
Then O2 is released from the air to the lungs, and CO2 is picked up. The frog then lowers its jaw, to lower the pressure in the mouth, to let the air travel from the lungs, to the mouth and into the outside,
hope that helped!
What else can I help you with?
What is Intrapulmonary pressure?
The intrapulmonary pressure is the pressure in the alveoli. Intrapulmonary pressure rises and falls with the phases of breathing, but it ALWAYS eventually equalizes with the atmospheric pressure.
Does a frog have gills and lungs?
toads do not have lungs,but they do breathe underwater. their skin absorbs the water which brings the oxygen into their bodies to help them breathe easily underwater. CORRECTION: Toads do in fact have lungs. Unlike many frogs, toads have dry skin but when in water they are still able to exchange gases through their skin in its moist state. Nevertheless, toads do have lungs, and draw air into their mouths and using their jaw muscles, force the air down into their lungs using positive pressure. It all depends on the species of toad, but both mechanisms for gas inhalation supplement each other.
How does the action of the external intercostal and diaphragm muscles draw air up your nose?
External intercostal and diaphragm increase the volume of the lungs, this action dicreases the pressure of the lungs. (we know pressure moves from the region of higher region to lower, in this case pressure is high in atmosphere and low in lungs). So air gets drew up in our nose.
How can you draw air pressure?
draw clouds
What happens when we breathe?
We draw air into, and expel out of, the lungs.
Why do you inject aspirated air from the syringe into the vital of diluent when you are reconstituting a drug for injection?
creates positive pressure that lets you draw the diluent easily. If you do not add air, a vacuum forms, making it difficult to draw the diluent.
Does the diaphragm move up on inhalation?
No, the diaphragm moves down during inhalation. This action increases the space in the chest cavity, allowing the lungs to expand and fill with air. The downward movement of the diaphragm creates negative pressure in the chest, which draws air into the lungs.
What does a ribcage do?
The rib cage serves two functions. It primary function is protection for the heart and lungs. Without this protection fatal damage could too easily occur. The second and far lesser function is in being part of the system (with the intercostal muscles) to pull the chest up to increase negative pressure on the lungs and draw in breath.
What is the definition to draw in breath?
To fill your lungs by sucking in air.
What happens to amp draw as static pressure increases?
As your static pressure increases your Amp draw will drop
What is your diaphram?
The diaphragm is a dome-shaped muscle located beneath the lungs and separates the chest cavity from the abdominal cavity. It plays a vital role in the process of breathing by contracting and expanding to help draw air into the lungs and then expelling it.
What action does the diaphragm perform to draw air into the lungs?
The diaphragm contracts and moves downward during inhalation, increasing the volume of the thoracic cavity. This creates a negative pressure within the lungs, causing air to flow in through the respiratory passages. As the diaphragm relaxes, it moves back to its original position, helping to expel air from the lungs during exhalation. This process is essential for efficient breathing.
