The mouth is the entry point for food where mechanical and chemical digestion begins.
The liver produces bile and processes nutrients.
The regions of the stomach are the fundus, body, and pylorus.
Ingestion is the intake of food.
CCK stimulates bile release and pancreatic enzyme secretion.
Emulsification is the process of breaking down fat globules into smaller droplets to increase surface area for enzymes.
Proteases digest proteins into amino acids.
The large intestine absorbs water and electrolytes and compacts waste into feces.
Fats are emulsified by bile and broken down by lipases into fatty acids and glycerol.
Frogs have a tongue used for capturing prey, and their stomach and intestines are adapted for digesting whole prey.
The components of the large intestine are the cecum, colon, rectum, and anus.
Mechanical digestion is the physical breakdown of food, such as chewing and churning.
Secretin stimulates bicarbonate secretion from the pancreas.
The esophagus is a muscular tube that transports food to the stomach via peristalsis.
The gallbladder stores bile.
The small intestine is the major site for nutrient absorption, aided by enzymes from the pancreas and bile from the liver.
Chemical digestion is the enzymatic breakdown of macromolecules into smaller molecules.
Chyme is a semi-fluid mass of partially digested food expelled by the stomach into the small intestine.
The stomach secretes gastric juices for further digestion and churns food into chyme.
Elimination refers to the removal of indigestible substances as feces.
The small intestine consists of the duodenum, jejunum, and ileum.
Absorption primarily occurs in the small intestine.
Absorption in earthworms occurs in the intestine, with nutrients absorbed directly into the bloodstream.
Carbohydrates are broken down by amylases into simple sugars.
Earthworms have a simple tube digestive system where food passes through a crop and gizzard for grinding.
Peristalsis is the wave-like muscle contractions that move food through the digestive tract.
The pancreas produces digestive enzymes and bicarbonate.
Gastrin stimulates gastric acid secretion.
