Which of the following is a primary result of pancreatic dysfunction?

A. Luteinizing hormone (LH) is involved in the regulation of the menstrual cycle and ovulation, but it is not responsible for uterine contractions or milk production.
B. Lactogen (also known as human placental lactogen) is produced during pregnancy and helps prepare the breasts for milk production, but it does not trigger uterine contractions.
C. Oxytocin plays a key role in both uterine contractions during labor and milk ejection during breastfeeding. It is sometimes referred to as the "love hormone" because it is also involved in bonding and emotional connections.
D. Prolactin is responsible for stimulating milk production in the mammary glands, but it does not cause uterine contractions. Oxytocin is the hormone responsible for that function.

A. Peristalsis, the movement of food through the digestive tract, is inhibited by sympathetic stimulation. The "fight-or-flight" response prioritizes immediate physical needs over digestion, decreasing peristalsis.

B. Bladder tone decreases with sympathetic stimulation. The sympathetic nervous system causes the bladder to relax, inhibiting urination in stressful situations.

C. Heart rate increases with sympathetic stimulation. The sympathetic nervous system activates the "fight-or-flight" response, which includes increasing heart rate to supply more oxygen and nutrients to muscles.

D. Saliva production decreases with sympathetic stimulation. During stress or danger, the body reduces non-essential activities like salivation to focus on more critical survival functions.
