            INSTRUCTIONAL OBJECTIVES: The pupil                                     SPECIFICATIONS: The pupil

1. acquirers knowledge about the structure of human                             1.  recalls the different system of human body.

    respiratory system.                                                                                        2.  recognises various organs involved in respiration.

2. understands the structure and various organs involved                                    3.  gives reason for the importance of respiration

    in human respiratory system                                                              4.  identifies various organs and gases involved in respiration.

3. applies his knowledge in identifying various organs                             5.  defines the process of respiration.

    in human body.                                                                                             6.  locates various organs in respiratory system.

4. develops skill in observing, drawing and labeling.                                           7.  infers the function of plural cavity.

5. develops interest in knowing more about human physiology.               8.  observes the structure of human respiratory system

6. develops scientific attitude towards the study of human physiology     9.  draws the diagram of human respiratory system.

    and  appreciates the structure of human lungs and its functions.                     10.  realizes the significance of human respiratory system.

            TEACHING AIDS:

1.      Chart showing the diagram of human respiratory system.

2.      Chart showing the diagram of  alveoli

recalls identifies recalls identifies locates identifies gives reason	Digestive system, Respiratory system, Nerves system, Excretory system Etc. Respiratory system Respiration Oxygen and Carbon dioxide Atmosphere Lungs The lungs are found in thoracic cavity A pair of lungs Oxygen is necessary for oxidation of food in the tissues. This oxygen is got from the atmosphere through respiration.	What are the different systems in human  body ? Which system is concerned with  respiration ? What is the process responsible for oxidation of food in the body ? What are the two major gases involved in respiration? Where do you get oxygen for respiration ? What is the main organ in respiratory system? Locates their own lungs in their body How many lungs are there in human respiratory system? Why the respiratory system is very Important?	A pair of lungs involved in respiration.          Yes/ No The process of respiration is very essential for oxidation of food.                Yes/No

defines recognises observes draws locates gives reason	Respiration is the process of exchange of Oxygen and carbon dioxide between the  body and the outside environment. Nostrils, pharynx, larynx, trachea, bronchi And bronchioles. Diagram of human respiratory system pharynx, larynx, trachea, bronchi The hair present inside the nostril prevent the large  unwanted particles entering the respiratory  system	Define the process of respiration? Tr. Explain various organs involved in Respiration Tr. Shows the chart Draws the diagram of human respiratory System Locates the various organ in human  respiratory system Why should there be hairs present in the nostrils.	Respiratory system helps you to breath                   Yes/No What are the organs involved  in respiration? Do you think breathing  through mouth is good?

Infers recognizes observes draws labels gives reason realizes the  significance	It products lungs Each alveolus is about 0.2 mm in diameter. It is lined by a single layer of epithelial cells. The alveolus is covered by blood capillaries Diagram of structure of alveoli During running race our body needs more  oxygen. So we inhale more oxygen. Respiration is an inevitable activity of all  living organisms. Oxygen is got from atmosphere through respiration	What is the function of plural cavity? Tr. Explain the structure of alveoli Tr. Shows the chart Draw the diagram of structure of alveoli Why we inhale more air during a running race? Explain the importance of respiratory system	Lungs are protected by double walled membrane called----- In lungs there are about------- alveoli. a)200million  b) 3000million c)130million  d) 300million The rate of respiration for a  minute depends upon the need of ------------------.

                         

                         REVIEW:    Process of respiration – Structure of respiratory pathway- nostrils, pharynx, larynx, trachea, lungs, alveoli –

                                                importance of  respiratory system.

                         ASSIGNMENT: 1. Buy a sheep lung from a butchers shop and observe the alveoli through hand lens.

                                                      2. Prepare a model of respiratory system.

                                                      3. What is larynx? Explain about it?
