to stop the flow of liquid if it gets turned upside down or falls over
What prevents milk from coming out your nose when upside down?
When you drink milk, it enters your stomach through the esophagus, which has a valve called the lower esophageal sphincter (LES) that prevents the flow of stomach contents back into the esophagus. This valve remains closed, even when you are upside down, reducing the likelihood of milk coming out of your nose. Additionally, the nasal cavity is separate from the esophagus, so milk does not typically flow into the nose during normal swallowing.
What is recording earth thermometer?
the earth thermometer measures air temperature.to forecast air temperature accurately,forecasters put he thermometer in a little house-like container.this containerhas openings on all sides to allow air to flow through.the earth thermometer must be protected from the sun.
What are the similarities in a lava flow and a pyroclastic flow?
A lava flow is simply a flow of liquid rock down a slope that usually results from an effusive eruption. A pyroclastic flow is an avalanche-like flow of hot ash, rock and gas that moves down a volcano during an explosive eruption, The move much faster than lava flows and are far more dangerous.
Cold weather slows down the process of?
a liquid to flow.
Why clinical thermometer is jerked before using it again?
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
How do bats sleep upside-down?
because they need the blood flow to their brain
Why is there a constriction in a clinical thermometer?
The constriction prevents the mercury from returning back to the bulb when the thermometer is removed from a particular body.

Why there is kink in clinical thermometer?
In a normal clinical thermometer, the mercury moves up and down the capillary tube as the temperature changes and thus if you removed it from contact with the patient the reading would steadily fall as it cooed. As you need a clinical thermometer to give you a reading of the patients temperature even after it has been removed from the patient, you need to stop the mercury shrinking back into the reservoir. The 'kink' breaks the connection between the mercury in the capillary tube and the reservoir so the reading given is accurate. On the other hand before it can be used again the mercury in the capillary tube has to be vigorously shaken back into the reservoir.On a point of interest, clinical thermometers are getting very rare because they have been phased out due to concerns regarding mercury poisoning should they break in use.
Why does the mercury fall or rise in a clinical thermometer when it is taken out of the mouth?
A clinical thermometer measures the max temp of the human body due to the expansion of the mercury in the bulb, which flows past a kink in the column and rises in the graduated stem, to read the highest body-temp. Once it is removed from the body, the mercury stays at that level, and does not fall because it cannot flow back into the bulb -- the kink prevents the back flow. It has to be shaken vigorously, as you know, for us to get the mercury back; then it is ready to take the temp again.. Also, the temp cannot rise further on its own from the max reading because the mercury does not expand the moment the thermometer is taken out of the body. Incidentally, temp can be measured under the armpits and in the rectum also.
Why is there bend in a clinical thermometer?
It is made prismatic to refract maximum light towards its base & make mercury shining. It makes easy to take reading.
What body position allows more blood flow to the head?
if you are upside down then more blood will be rushed to your head due to gravity
Why does your nose bleed when your upside down?
If upside down, your blood flow to your head due to gravity.
How do you restore fuel pump operation flow after roll-over rollover upside-down upside down on a 96 grand Cherokee?
im not 100% sure but many cars have a reset switch at the roll over valve, i have no idea where it is on the car i can only guess its on the fuel pump
What is the use of a kink in a thermometer?
You're referring to alcohol or mercury thermometers used to take person's temperature?That constriction slows the flow of the alcohol back into the bulb after the thermometer is removed from your mouth (or elsewhere) so the temperature can be read more accurately. Otherwise the indicated temp would begin to decrease as soon as the bulb is moved to a cooler environment.That why you see the nurse shaking the thermometer down before use, to get all the alcohol back into the bulb so it can re-expand properly before the next use.
Can you breathe while choking?
This would follow the same principal as swallowing when your upside down. Because humans swallow because of muscles in the pharynx and esophagus, not because of gravity, it must possible to choke when you are upside down.
