Transport Flashcards
What is the function of the oesophagus?
Transport food from mouth to stomach
The oesophagus is a muscular tube that connects the throat (pharynx) with the stomach.
What enzymes are secreted by the salivary glands?
Amylase
Amylase helps in the digestion of carbohydrates.
What is the primary function of the stomach?
Digestion of food
The stomach secretes acid and enzymes that help break down food.
What role does the pancreas play in digestion?
Secretes digestive enzymes
The pancreas produces enzymes such as lipases and proteases that aid in the digestion of fats and proteins.
What are the key functions of the small intestine?
Digestion and absorption of nutrients
The ileum is the final part of the small intestine where most nutrient absorption occurs.
What is the primary function of the large intestine?
Absorption of water and formation of feces
The large intestine also plays a role in the fermentation of unabsorbed material.
What is the function of the rectum in the digestive system?
Stores feces before excretion
The rectum is the final section of the large intestine.
What is the role of enzymes in digestion?
Break down food into smaller molecules
Enzymes such as amylase, lipase, and proteases facilitate the digestion process.
Fill in the blank: The _______ is responsible for the mechanical digestion of food.
Stomach
True or False: The salivary glands produce lipases.
False
Salivary glands primarily produce amylase, not lipases.
What adaptations help the oesophagus function effectively?
Muscular contractions and mucus secretion
These adaptations help move food along the digestive tract.
What is the bolus in the context of digestion?
A lump of food mixed with saliva
The bolus is formed in the mouth before swallowing.
What is the importance of blood supply in the digestive organs?
Maintains nutrient absorption and transport
Adequate blood supply is crucial for delivering absorbed nutrients to the rest of the body.
