Digestive System Quiz

Peritoneum and Organs

• Parietal peritoneum lines the walls of the abdominal cavity.
• Organs covered with visceral peritoneum are referred to as intraperitoneal organs.
• An example of an intraperitoneal organ is the stomach.
• The space outside the parietal peritoneum is called the retroperitoneal space.
• A retroperitoneal organ example is the kidney.
• The lesser omentum attaches the stomach to the liver.

Mesentery and Omentums

• The mesentery anchors the intestines to the posterior abdominal wall and supports blood vessels and nerves.
• The greater omentum is a large fold of peritoneum hanging from the stomach, known for its fatty deposits and immune functions.

Digestive Tract Anatomy

• The section of the digestive tract that includes the mouth, pharynx, esophagus, and stomach is the upper gastrointestinal tract.
• The innermost layer of the gastrointestinal wall that faces the lumen is the mucosa.
• The submucosa layer contains the main blood vessels, nerves, and glands.
• The muscularis layer has an inner circular layer and an outer longitudinal layer composed of smooth muscle.
• The outermost layer of the gastrointestinal wall is the serosa, which is interchangeable with the visceral layer of the peritoneum.

Peritoneum Structure

• Visceral peritoneum lines the organs within the abdominal cavity.
• Parietal peritoneum lines the abdominal cavity walls.
• The entire digestive tube passes through the abdominopelvic cavity.
• The peritoneum covers most of the digestive organs.

Bile Production

• The liver is the accessory organ responsible for producing bile.
