Answer 1

Explanation:

(a) Gastric Sphincter : Controls the release of food from the stomach to small intestine. (b) Anal Sphincter : Controls the release of undigested waste from the rectum through the anus.

Answer 2

Answer:

Stomach Spincter - The pyloric sphincter is a small piece of smooth visceral muscle that acts as a valve and regulates the flow of partially digested food from the stomach to the duodenum. The opening and closing of the sphincter is controlled by peristaltic waves produced by the stomach during the digestion process.

Anal Spintcer - The external anal sphincter provides voluntary control for defecation. As the rectum gradually fills with feces at rest and after meals, the continuous tonic contraction of the external anal sphincter helps to prevent defecation.
