| The ability of sperm to move efficiently; a key predictor of male fertility and successful fertilization. | Sperm motility |
| Which phase of the menstrual cycle occurs between ovulation and the onset of menses? | The luteal phase |
| Which mechanical digestion processes involve the esophagus? | deglutition and peristalsis |
| A hormone released by the small intestine that stimulates gallbladder contraction and pancreatic enzyme secretion | Cholecystokinin (CCK) |
| Oxytocin feedback in normal labor | Oxytocin normally functions via positive feedback to intensify uterine contractions during labor |
| Which hormone is released by juxtaglomerular (JG) cells? | Renin |
