10 Questions
Which organs are considered accessory digestive organs?
Liver, gallbladder, and pancreas
What is the function of gastric motility in the digestive system?
To mix and move materials along the GI tract
What is the main function of the liver, gallbladder, and pancreas in the digestive system?
Produce and store digestive secretions
What is the process of absorption in the digestive system?
Uptake of nutrient molecules into the blood/lymph by the small intestine
What is the main function of chemical digestion in the GI tract?
To break down macromolecules into their monomers using digestive enzymes
Mechanical digestion only involves the physical breakdown of food, while chemical digestion involves the breakdown of food into its nutrient molecules.
True
The main function of the liver, gallbladder, and pancreas in the digestive system is to directly absorb nutrients from the food.
False
The capability of the GI tract to mix and move materials along its length is known as gastric motility.
False
Chemical digestion involves the breakdown of dietary macromolecules into their monomers through hydrolysis reactions carried out by digestive enzymes.
True
The process of absorption in the digestive system involves the uptake of nutrient molecules into the blood/lymph by small intestines.
True
Study Notes
Accessory Digestive Organs
- The liver, gallbladder, and pancreas are considered accessory digestive organs.
Gastric Motility
- Gastric motility refers to the capability of the GI tract to mix and move materials along its length.
- This function is essential in the digestive system.
Functions of Accessory Digestive Organs
- The main function of the liver, gallbladder, and pancreas is to facilitate chemical digestion in the digestive system.
- The liver produces bile, the gallbladder stores bile, and the pancreas produces digestive enzymes.
- These organs work together to break down food into its nutrient molecules.
Mechanical vs Chemical Digestion
- Mechanical digestion involves the physical breakdown of food into smaller pieces.
- Chemical digestion involves the breakdown of food into its nutrient molecules through hydrolysis reactions carried out by digestive enzymes.
Absorption
- The process of absorption in the digestive system involves the uptake of nutrient molecules into the blood or lymph by the small intestines.
- This is an essential step in the digestive process, allowing the body to utilize nutrients from ingested food.
