Fluid Pressure Measurement. The fact that the liquid levels are the same in these three manometers shows that the pressure in the glass manifold above them is uniform. This is under static conditions with no air flow through the system so that all parts of it are at atmospheric pressure.
The relationship between endometriosis and infertility is not completely understood. The primary cause of infertility resulting from endometriosis appears to be a blockage caused by scarring and adhesions in the tubes. These adhesions can prevent the egg and sperm from meeting or prevent the fertilized egg from moving down the tube normally (resulting in an ectopic pregnancy).
Symptoms of endometriosis can include: 1  Pain. This is the most common symptom. 2  Bleeding or spotting between menstrual periods. This can be caused by something other than endometriosis. 3  Infertility, or not being able to get pregnant.  Stomach (digestive) problems.
