Human
respiratory system
|
Pupil teacher
will ask to enlist parts of human respiratory system.
|
Pupil will say
lungs, nostrils, wind pipe, bronchi, e.t.c.
|
Brain storming
lungs, nostrils,
wind pipe, bronchi, e.t.c.

|
With the help of
chart on human respiratory system,
pupil teacher will reemphasis the parts of human respiratory system
mentioned by students.
|
Pupils will
listen properly and remember these parts
|
Chart on human
respiratory sytem
|
Identify the parts
of human respiratory system you know.
|
|
Diagram of
human respiratory system
|
Pupil teacher
will ask students to draw diagram of human respiratory system while he draws
on the board.
After finished
drawing, labeling is done with brief explanation.
|
Pupils draw ing
their notebook
|
|
Draw diagram of
human respiratory system
|
Nasal
passage
|
Pupil teacher will ask
What do you call
for the two opening of nose?
What is present
in these nostrils?
Pupil teacher
will explain that nostrils are two opening present in nose and bear hairs and
have mucus which traps foreign particles.
Nasal passage
starts from nostrils which are connected to nasal chamber leading to pharynx linked
with trachea.
|
Nostrils
Hairs and mucus
|
Nasal passage starts
from nostrils which are connected to nasal chamber leading to pharynx linked
with trachea.
Nostrils are two
opening present in nose, bear hairs and have mucus which traps foreign
particles.
|
Explain nasal
passage.
What is function
of hairs present in nasal chamber?
|
Trachea
(Wind pipe)
|
Trachea is C-shaped ring like structure stacked one on
another
|
Note down in
notebook
|

another
|
Describe trachea.
|
Lungs
|
What is the
respiratory organ of human?
How many lungs
are present in human?
Pupil teacher
will explain that lungs are two in number(A pair). Lung located at left position in the chest
cavity is known as left lungs and other located in the right position inside
chest cavity is right lungs.
|
Lungs
A pair of lungs
|
Lungs: A pair in
number. Can be either left lung or right lung.
|
What is human
respiratory organ?
Summerise what we
have studied about lungs.
|
Alveoli
|
What do you think
about shape and role of alveoli?
With the help of flash
card on alveoli pupil teacher will explain
alveoli are small
sac like structure present in the lungs which are provided with network of
blood capillaries and they help in exchange of respiratory gases.

Flash card on
alveoli
Alveoli: Small sac
like structure present in the lungs which are provided with network of blood
capillaries and they help in exchange of respiratory gases.

diaphragm?
Pupil teacher
will explain that diaphragm is muscular floor present below lungs. These
helps in respiration
