  • Which statement best describes the role of salivary glands?
    They create insulin
    They break down fats
    They produce saliva
    They process blood
  • What is a bolus?
    A digestive enzyme
    A type of tooth
    A section of the digestive tract
    A ball of chewed and softened food
  • The digestive system's primary role in ingestion is to:
    Store food for later use
    Remove waste products
    Produce digestive enzymes
    Break down food into substances for organs and cells
  • Which of the following best describes the role of saliva during ingestion?
    It softens the food
    It begins protein digestion
    It kills harmful bacteria
    t produces digestive enzymes only
  • What structure in the mouth helps form food into a bolus?
    Teeth
    Tongue
    Esophagus
    Salivary glands
  • After the stomach, food moves to which organ?
    Small intestine
    Large intestine
    Esophagus
    Pharynx
  • What is the primary function of bile produced by the liver?
    To process blood
    To create digestive enzymes
    To break down fat into smaller pieces
    To produce insulin
  • The purpose of breaking down food during ingestion is to:
    Make swallowing easier
    Extract vitamins and minerals immediately
    Kill harmful bacteria
    Provide immediate energy to the body
  • How does the liver contribute to blood circulation?
    By processing digested food in blood before circulation
    By creating insulin
    By producing enzymes
    By storing excess nutrients
  • What role do teeth serve in digestion?
    They absorb nutrients
    They identify food flavors
    They secrete digestive enzymes
    They break down food into smaller pieces
  • What are the three accessory glands mentioned in the text?
    Salivary glands, pancreas, and liver
    Liver, gallbladder, and pancreas
    Salivary glands, stomach, and liver
    Pancreas, stomach, and intestines
  • Which gland is responsible for producing insulin to metabolize glucose?
    The pancreas
    The liver
    The gallbladder
    The salivary glands
  • Which correctly describes the digestive tract?
    A series of disconnected organs
    A muscular tube with varying diameter
    A rigid pathway for food
    A straight, uniform tube
  • In what organ does the initial mechanical breakdown of food occur?
    Small intestine
    Esophagus
    Stomach
    Mouth
  • During ingestion, what happens immediately after food enters the mouth?
    It is absorbed into the bloodstream
    It moves to the stomach
    It begins to be broken down by teeth
    It forms into a bolus
  • What is one of the main functions of the pancreas?
    Filtering blood
    Creating bile
    Producing saliva
    Providing digestive enzymes
  • What is the primary function of teeth during ingestion?
    To trigger saliva production
    To break down food into smaller pieces
    To mix food with saliva
    To form the bolus
  • What does the liver do with digested food from the blood?
    Converts it to bile
    Processes it before blood circulation
    Transforms it into enzymes
    Stores it for later use
  • Which component is NOT directly involved in the ingestion process?
    Tongue
    Saliva
    Teeth
    Small intestine
  • What is the primary function of the digestive system?
    To produce hormones
    To convert food into absorbable nutrients
    To regulate body temperature
    To transport oxygen throughout the body
  • What structure is responsible for identifying flavors during digestion?
    Pharynx
    Tongue
    Teeth
    Esophagus
  • What does the stomach secrete to aid in food breakdown?
    Insulin
    Gastric juices
    Bile
    Saliva
  • The digestive system consists of which two main components?
    Stomach and intestines only
    Muscles and bones
    Blood vessels and nerves
    Digestive tract and accessory glands
  • What is the correct sequence of food passage through the digestive system?
    Mouth → esophagus → stomach → intestines
    Mouth → stomach → pharynx → esophagus
    Mouth → pharynx → esophagus → stomach
    Mouth → pharynx → stomach → esophagus
  • What is ingestion in the digestive process?
    The absorption of nutrients in the small intestine
    The movement of food through the intestines
    The breakdown of food in the stomach
    The entry of food into the digestive tract through the mouth
  • Where are the salivary glands located?
    Under the tongue, in the jaw, and near the ears
    In the liver and pancreas
    Only under the tongue
    In the stomach and intestines
  • Which sequence correctly orders the stages of early digestion?
    Ingestion, chewing, swallowing, digesting
    Chewing, ingestion, digesting, swallowing
    Swallowing, ingestion, chewing, digesting
    Digesting, swallowing, ingestion, chewing
  • Which statement about the digestive system is correct?
    It eliminates all food components
    It only breaks down food into smaller pieces
    It only absorbs nutrients
    It processes useful nutrients and eliminates waste
