Question

Quizplus · Accepted Answer

Hormones, such as gastrin and secretin, are released into the bloodstream and travel to the digestive system to alter motility and secretion.

Answer: B 
 Extrinsic (autonomic) nerves innervate the digestive system and modify its function.

Answer: D 
 Intrinsic nerve plexuses, such as the myenteric plexus, control the peristaltic activity of the gastrointestinal tract.

Answer: A 
 Autonomous smooth muscle function refers to the inherent ability of smooth muscle to contract and relax independent of neural or hormonal input, allowing for rhythmic contractions of the digestive system.
