CONTENT ANALYSIS
TERMS
Salivary gland, intestinal gland, gastric gland, liver, pancreas etc.
FACTS
Salivary glands are situated in buccal cavity.
Salivary gland secretes saliva.
Saliva contains salivary amylase.
Salivary amylase converts starch to maltose.
Gastric glands are situated in the stomach.
Gastric glands secrete gastric juice.
It contains lipase and pepsin.
Lipase converts lipids into fatty acids.
Pepsin converts protein into poly peptides.
Liver is the largest gland.
Liver secrete bile.
Bile emulsifies fat.
Pancreas secrete pancreatic juice.
Pancreatic juice contain trypsin, amylase and lipase.
Trypsin acts on protein.
Amylase acts on starch.
Lipase acts on lipids.
Intestinal glands are situated in small intestine.
It secretes intestinal juice.
It is a mixture of maltase, sucrase and peptidase.
Maltase converts maltose into glucose.
Sucrase converts sucrose into glucose and fructose.
Peptidase converts peptides into amino acids.
CONCEPTS
MINOR CONCEPTS
Salivary gland is situated in the buccal cavity, secretes saliva containing salivary amylase
which converts glucose into maltose.
Gastric glands are present in the stomach which secrete gastric juice, a combination of
enzymes viz. lipase and pepsin.
Liver secrete bile which emulsifies fat.
Pancreas secretes pancreatic juice which is a combination of trypsine, amylase and lipase.
Intestine glands are situated in small intestine which secrete intestinal juice which is a
combination of peptidase and disacharidase.
MAJOR CONCEPTS
Salivary gland, gastric gland, pancreas, liver and intestinal glands are the digestive glands of
human digestive system which secrete digestive juices containing digestive enzymes which
aids chemical process of digestion.
CURRICULAR OBJECTIVES
CONCEPTUAL DOMAIN:
To develop remembering and understanding of the above
mentioned terms such as Salivary gland, gastric gland,
pancreas, liver and intestinal glands and facts and the concept
of digestive glands.
PROCESS DOMAIN:
To develop process skills like observing, classifying, predicting,
inferring etc through group activities related to the topic.
CREATIVITY DOMAIN:
To develop components of creativity like visualising, divergent
thinking etc in pupils.
ATTITUDINAL DOMAIN:
To develop right attitude towards digestive glands and their
importance.
APPLICATIONAL DOMAIN:
To develop application of the acquired knowledge, skill etc in a
new or unfamiliar situation like health problems.
METHODS AND TECHNIQUES USED
Lecture method, group activity method.
LEARNING AIDS USED
Black board.
EVALUATION TECHNIQUES USED
Review.
Continuous evaluation by asking questions.
ENTRY BEHAVIOUR
Pupils know that in humans digestion takesplace in digestive systems.
PROCESS COMPETENCIES
Observation skill, communication skill etc are developed in pupils.

CLASS ROOM INTERACTION PROCEDURE
ITRODUCING ACTIVITY:
ANTICIPATED RESPONSE
Students answer the questions.
ACTIVITY No-1
Teacher creates a rapport in the class. Then
writes the topic digestive glands on the black
board. Check previous knowledge of the
students by asking questions related to
digestion, digestive system etc.
ACTIVITY No- 2
Pupil says salivary gland.
Teacher says a puzzle as

“I am a gland. I reside in mouth. My discussion.
secretion is saliva. Can you identify me”.
Identify the gland and conduct group
discussion using hints.
HINTS
Salivary amylases
Carbo hydrates -> Maltose
CONSOLIDATION
Salivary gland is seen in buccal cavity. It secretes salivary amylase. Salivary amylase acts on
carbo hydrates and converts it into maltose.
ACTIVITY No- 3
Gastric gland.
“My secretion is a combination of lipase and Acts on fats and protein.
pepsin. My home is J shaped. Can you tell
who am I?” Identify the gland and with the
help of hints discuss on its site of action?
HINTS
Lipase : Lipids -> Fatty acids
Pepsin: Protein -> Peptides
CONSOLIDATION
Gastric glands are situated in stomach. They secrete gastric juice which is a combination of
lipase and pepsin. Lipase converts lipids into fatty acids. Pepsin converts protein into
peptides.

storage and detoxification in addition to
digestion. Can you tell who am I?” Identify
the gland and discuss using hints?
HINTS:
Bile
Emulsification of fat.
CONSOLIDATION
Liver secretes bile which help in the emulsification of fat.
ACTIVITY No- 5
Pancreas

Any abnormalities in my function leads to
diabetes. Can you tell who am I?” Identify
the gland and conduct group discussion
based on hints.
HINTS:
Pancreatic juice.
Trypsin: Protein -> Peptides.
Amylase : Maltose -> Glucose and
fructose.
Lipase : Lipids -> Fatty acids and glycerol.
CONSOLIDATION
Pancreas secretes pancreatic juice which is a combination of pancreatic trypsin, pancreatic
amylase and pancreatic lipase. Trypsin converts protein into peptides. Amylase converts
maltose into glucose and fructose. Lipase acts on lipids and converts it into fatty acids and
glycerol.
ACTIVITY No- 6
Intestinal glands.
“I am situated in small intestine. I secretes Group discussions have to be conducted by
HCl and digestive enzymes. Can you tell who students.
am I?” Conduct group discussion on my
secretion based on hints.
HINTS
Maltase : Maltose -> Glucose.
Peptidase : Peptides -> Amino acids.
Disaccharidase : Disaccharides -> Mono
saccharides.
CONSOLIDATION
Intestinal glands are situated in the small intestine secrete intestinal juice which is a
combination of HCl and digestive enzymes peptidase and disaccharidase. Digestion gets
completed in small intestine.

BIOLOGY
Digestive glands
Salivary gland -> Saliva -> Salivary amylase.
Gastric glands -> Gastric juice -> Lipase, pepsin.
