  • If pelvic inflammatory disease is present, the fallopian tubes may become scarred and possibly cause later infertility or other reproductive problems.

  • Pelvic inflammatory disease (PID)-Any infection of the lower female reproductive tract (vagina and cervix) that spreads to the upper female reproductive tract (uterus, fallopian tubes and ovaries).

  • Once in place, the tubes are connected to the ECMO circuit, and then the machine is turned on.

  • Venoarterial (V-A) bypass-The type of extracorporeal membrane oxygenation that provides both heart and lung support, using two tubes (one in the jugular vein and one in the carotid artery).

  • It differs from primary dysmenorrheal in that the pain is caused by an abnormality or disease of the uterus, tubes, or ovaries.

  • Sometimes during development these two tubes do not separate completely but remain connected by a short passage.

  • The whoop is believed to occur due to inflammation and increased mucus, which narrow the breathing tubes, causing people to struggle to get air into their lungs; the effort results in intense exhaustion.

  • If a newborn infant is to breathe properly, the small air sacs (alveoli) at the ends of the breathing tubes must remain open so that oxygen in the air can get into the tiny blood vessels that surround the alveoli.

  • Normally, the two tubes form separately (differentiate); however, in the case of EA/TEF, they do not differentiate, which results in various malformed configurations.

  • The changes that take place in the lungs of people with asthma make the airways (the "breathing tubes," or bronchi and the smaller bronchioles) hyper-reactive to many different types of stimuli that do not affect healthy lungs.

  • Postural drainage-The use of positioning to drain secretions from the bronchial tubes and lungs into the trachea or windpipe where they can either be coughed up or suctioned out.

  • These adenoids may enlarge with repeated respiratory tract infections and ultimately block the eustachian tubes.

  • When these tubes are blocked, the middle ear is more likely to fill with fluid, which in turn increases the risk for infection.

  • If OME persists for more than four to six months, even if hearing tests are normal, the doctor may suggest surgery to drain the eardrum and implant ear tubes for continuous drainage.

  • Most of the time, the egg remains in the fallopian tubes; hence an ectopic pregnancy is commonly referred to as tubal pregnancy.

  • You start out with two ovaries and two tubes so even if one tube is damaged by an ectopic pregnacy, you can still conceive with the other ovary and tube.
