Chyme from entering the colon (Large intestine).
If the blockage is impinging on the vagus nerve, yes a blockage in the carotid artery can cause nausea. However, most common signs would include feeling faint, difficulty thinking (particularly for complicated or long-term tasks) and lack of energy.
The mitral valve (or bicuspid valve) is the left atrioventricular valve. That means the left atrium would receive blood flow from the left ventricle (the wrong direction) if there was a regurgitation in that valve.
Damage to the left semilunar valve would interfere with blood flow to the aorta.
The mitral valve between the left atrium and ventricle.
birth defect
The function of your ileocecal valve is to prevent waste from your large intestine from flowing back into your small intestine. This would cause the waste juices to get mixed in with the nutritional juices.
I believe it would be the ileocecal valve reflex
You would not be able to keep your food down and you would puke it up.
Hose blockage, core blockage, disconnected heat valve.
there is a blockage either in supply pipe or refill valve.
could be a lack of pressure, or a lime blockage in the seat of the valve, turn water off to valve, remove the stem, turn water on then back off, this might clear any blockage,
yes. a valve in the open position will prevent compression, thus no combustion.
air lock in the poportioning valve
It could be gas trapped in the intestines or it could be that the intestines are having a problem moving waste through. There is a possibility of a problematic ileocecal valve (the valve that connects the small and large intestines.) If the pain was more severe, I would worry about peritonitis or appendicitis, but that's more than just an average tummy ache.
There is a "power valve" in carburetors that richens the air/fuel mixture when the throttle is suddenly opened to prevent a lean condition, which would make the motor stumble.
If you have a bent valve slide, or valve, or valve casing, they usually wont move. Valve's and valve casings would prevent the valves from moving, while bent valve slides wont easily pull out. If you suspect a bent valve, valve casing, or slide, try cleaning and oiling it first, valves and slides can become stuck with the lack of valve oil or slide grease.
The left atrioventricular valve stops the back-flow of blood by only being opened if a large force or pressure is behind it (in the left atrium) and is closed if a large force or pressure is in front of it (in the left ventricle).
