The pylorus of the stomach has cells that secrete which of the following?

The pylorus of the stomach contains specific types of cells that are primarily involved in the secretion of paracrine hormones, such as gastrin. These hormones play a crucial role in regulating digestive processes. Gastrin, for example, stimulates the secretion of gastric acid from the parietal cells of the stomach lining, which is essential for breaking down food and activating digestive enzymes.

In this context, paracrine hormones have a localized effect, acting on nearby cells and influencing physiological functions within the gastrointestinal tract. This local signaling is vital for coordinating the different phases of digestion, helping to ensure that the stomach operates efficiently.

While enzymes are secreted by the stomach, particularly from the gastric chief cells, they are not the primary secretion from the pyloric region. Electrolytes and neurotransmitters also have roles in the digestive system, but they do not specifically define the main function of the pylorus where paracrine hormone secretion is concerned.
