Final answer:
Acid-secreting cells in the stomach are controlled primarily by the hormone gastrin and are also influenced by both the nervous system and other hormones. so, option 1 is the correct answer.
Step-by-step explanation:
The acid-secreting cells of the stomach are controlled primarily by the gastric hormone gastrin, which is secreted in response to the presence of food. This hormone stimulates the secretion of gastric acid by the parietal cells of the stomach mucosa. Additionally, the secretion of gastric juice is regulated by both nerves and hormones, involving the enteric system and the autonomic nervous system, particularly the parasympathetic branch. This complex process of regulation ensures that gastric acid is secreted when needed for digestion and inhibited when not needed, maintaining a balance within the digestive system.
The acid-secreting cells of the stomach are controlled by hormones, such as gastrin, secretin, and cholecystokinin (CCK).
The acid-secreting cells of the stomach are controlled by hormones. Gastrin, which is secreted in response to the presence of food, stimulates the secretion of gastric acid by the parietal cells of the stomach mucosa. Other hormones produced by the duodenum, such as secretin and cholecystokinin (CCK), also play a role in regulating gastric acid secretion.
