  13. What mass is associated with a heat cycle after ovarian remnant syndrome?
  14. Why is it important to minimize uterine handling during intrauterine insemination?
    too much handling/trauma will cause release of prostaglandins--> insemination won't be successful

  18. What are clinical signs of pregnancy toxemia? (4)
    weakness, depression, seizures, coma
  19. Describe the cardiovascular effects of pregnancy. (4)
    increased plasma volume, decreased BP, intolerant of hypotension, demand of fetuses (increased oxygen consumption, increase CO2 production)
  20. Describe the respiratory effects of pregnancy. (3)
    decreased lung volume (not as much space), hypoxia, demand of fetuses (increase oxygen consumption, increase CO2 production) [consider pre-oxygenation of patient before C-section]
  21. Describe the GI effects of pregnancy. (3)
    gastric reflux, delayed gastric emptying, LES relaxation
  22. Describe the CNS effects of pregnancy and the implications of this.
    decreased minimal alveolar conc (MAC) inhalation anesthetics- its harder to keep a pregnant animal under
  23. If you're going to biopsy a uterus to determine the cause of a dead/macerated fetus, you must...
    biopsy at the site of placental attachment for the dead fetus.
  24. What do we usually do for pain management post- C-section?
    injectable narcotics; NSAIDs and tramadol not labelled for lactation
  25. In which species is penile erection NOT essential for function?
    dogs- os penis facilitates vaginal entry without full erection

    intersex condition
  27. Gonads of one gender and reproductive phenotype of the opposite; named based on gonads.
  28. The _________ regulates the distance of the testes from the body to control temperature.
