Answer 1

Answer:

The stomach is a 'J '- shaped muscular bag-like structure placed below the diaphragm on the left side of abdomen. It receives and mixes food with digestive juices, and propels food to the small intestine.

It contains a ring of muscles called pyloric sphincter that controls the release the food from the stomach into the small intestine. The internal lining of stomach contains many gastric glands.

Hope that helps....

Answer 2

Answer:

Digestive juices contain enzymes—substances that speed up chemical reactions in the body—that break food down into different nutrients.

SALIVARY GLANDS

Saliva produced by the salivary glands moistens food so it moves more easily through the esophagus into the stomach. Saliva also contains an enzyme that begins to break down the starches from food.

GLANDS IN THE STOMACH LINING

The glands in the stomach lining produce stomach acid and an enzyme that digests protein.

PANCREAS

The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. The pancreas delivers digestive juice to the small intestine through small tubes called ducts.

LIVER

The liver produces a digestive juice called bile. The gallbladder stores bile between meals. When a person eats, the gallbladder squeezes bile through the bile ducts, which connect the gallbladder and liver to the small intestine. The bile mixes with the fat in food. The bile acids dissolve fat into the watery contents of the intestine, much like how detergents dissolve grease from a frying pan, so the intestinal and pancreatic enzymes can digest the fat molecules.

SMALL INTESTINE

Digestive juice produced by the small intestine combines with pancreatic juice and bile to complete digestion. The body completes the breakdown of proteins, and the final breakdown of starches produces glucose molecules that absorb into the blood. Bacteria in the small intestine produce some of the enzymes needed to digest carbohydrates.
