1.1 Digestive System

• The stomach stores food and further digests it using gastric juices
• What does the liver produce to aid in fat digestion?

  Bile
• Peristalsis is the process used by the esophagus to move food to the stomach.

  True
• What is the function of the esophagus?

  Transports food to the stomach
• The large intestine absorbs water from undigested food.


  True
• Which organ stores and concentrates bile produced by the liver?

  Gallbladder
• What does the large intestine absorb from undigested food?

  Water
• Which enzyme in saliva starts the chemical digestion of carbohydrates?

  Amylase
• What is the primary function of the large intestine?

  Water absorption
• Which organ chews and breaks down food mechanically and chemically using saliva?

  Mouth
• What does the liver produce to aid in fat digestion?

  Bile
• The digestive process from mouth to anus

  1️⃣ Food enters the mouth and is chewed

  2️⃣ Food is transported to the stomach via the esophagus

  3️⃣ Food is stored and digested in the stomach

  4️⃣ Nutrients are absorbed in the small intestine

  5️⃣ Water is absorbed in the large intestine
• The stomach stores and further digests food using gastric juices
• What substance does the liver produce to help digest fats?

  Bile
• What is the role of the esophagus in the digestive system?

  Transports food
• Which organ stores and concentrates bile produced by the liver?

  Gallbladder
• Match the digestive enzyme with its location and target molecule:

  Amylase ↔️ Saliva, Pancreas ||| Carbohydrates

  Pepsin ↔️ Stomach ||| Proteins

  Lipase ↔️ Pancreas, Small Intestine ||| Fats

  Trypsin ↔️ Pancreas ||| Proteins

  Maltase ↔️ Small Intestine ||| Maltose
• Digestive enzymes are essential for the chemical breakdown of food.


  True
• Where is maltase produced, and what is its target molecule?

  Small Intestine, Maltose
• The liver produces bile to aid in the digestion of fats.
• Match the digestive organ with its function:

  Mouth ↔️ Breaks down food mechanically and chemically

  Stomach ↔️ Stores and digests food using gastric juices

  Small Intestine ↔️ Absorbs nutrients into the bloodstream

  Large Intestine ↔️ Absorbs water and stores waste

  Liver ↔️ Produces bile for fat digestion
• What substance does the liver produce to help digest fats?

  Bile
• Arrange the following organs in the order food passes through them during digestion:

  1️⃣ Mouth

  2️⃣ Esophagus

  3️⃣ Stomach

  4️⃣ Small Intestine

  5️⃣ Large Intestine

  6️⃣ Anus
• The mouth chews and breaks down food using saliva, which starts the chemical digestion of carbohydrates
• Where are most nutrients absorbed into the bloodstream?

  Small intestine
• The pancreas produces enzymes to aid digestion in the small intestine.
• Most nutrients are absorbed into the bloodstream in the small intestine
• Most nutrients are absorbed into the bloodstream in the small intestine.
• The gallbladder stores and concentrates bile produced by the liver.
• The small intestine absorbs nutrients into the bloodstream.


  True
• The gallbladder stores and concentrates bile produced by the liver.


  True
• What organ transports food from the mouth to the stomach?

  Esophagus
• The large intestine absorbs water from undigested food.


  True
• The mouth breaks down food mechanically and chemically using saliva
• The pancreas produces enzymes to aid digestion in the small intestine.
• The gallbladder stores and concentrates bile produced by the liver.


  True
• What is the target molecule for pepsin, which is produced in the stomach?

  Proteins
• Trypsin, produced in the pancreas, targets proteins.
• Which organ mixes food with saliva to start carbohydrate digestion?

  Mouth
• The mouth starts the chemical digestion of carbohydrates using saliva.
