Chyme from entering the colon (Large intestine).
To completely block any air from entering the respiratory system, the trachea (windpipe) would need to be obstructed. This would prevent air from reaching the lungs where gas exchange occurs. Additionally, blockage of the bronchial tubes leading into the lungs would also prevent air from entering the respiratory system.
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.
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 between the left atrium and ventricle.
It would be highly unusual for a male to have semen "stuck" in his genitourinary tract after he ejaculates. The semen should be thin enough to freely flow from his urethra without problem. If he is experiencing thickend secretions, including semen, he should get it checked out by a doctor because it could be a sign of a pretty serious condition.
I believe it would be the ileocecal valve reflex
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.
Without an ileocecal valve, there would be a risk of backflow of waste material from the colon into the small intestine, potentially leading to bacterial overgrowth and digestive issues. This valve also helps regulate the passage of digested food from the small intestine to the colon, so its absence could disrupt this process.
Hose blockage, core blockage, disconnected heat valve.
there is a blockage either in supply pipe or refill valve.
the valves of the heart prevent blood from flowing backwards, so if they are damaged the blood is allowed to flow backwards and then the oxygnated and deoxygnated blood get mixed. The person could get an artificial valve then.
Blockage of a ureter would cause urine to collect in the kidney, leading to potential complications such as infection, swelling, and decreased kidney function. Prompt medical attention is required to address the blockage and prevent further damage.
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.
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.
air lock in the poportioning valve
Total glomerular filtration would decrease due to the blockage of the collecting ducts, leading to reduced urine production. This blockage would prevent the reabsorption of water and solutes from the tubular fluid, resulting in a higher concentration of solutes in the urine that is formed.
