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?

Respiration is the process of exchange of
Oxygen and carbon dioxide between the
 body and the outside environment.

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

Why we inhale more air during a
running race?


Explain the importance of respiratory
system


Lungs are protected by double

In lungs there are about-------
alveoli.

2 ENGLISH BEFORE INDEPENDENCE AND ENGLISH NOW IN INDIA and present status

ENGLISH BEFORE INDEPENDENCE AND ENGLISH NOW IN INDIA:  Place of English before Independence- 30  India inherited English‘ from the Britishers who ruled our country for more than two centuries. For over 200 years Indian intellectuals have been studying English. Today English has entered the fabric of Indian culture. English education in India began with the year 1765, when the East India Company became a political power. The first six decades of English education in India did not witness any remarkable progress. Firstly Macaulay‘s Minutes (1835) paved the way for the development of English in India by making its study compulsory. His this famous minute on education became the ‗Manifesto of English Education‘  in India. Macaulay‘s minute is very clear and unambiguous about the goals of English education in India We must at present do our best to form a class who may be interpreters between us and the millions whom we govern a class of persons, Indian in blood and colo...

English language in the school context- an evolutionary perspective

2. GOALS FOR A LANGUAGE CURRICULUM  A national curriculum can aim for • a cohesive curricular policy based on guiding principles for language teaching and acquisition, which allows for a variety of implementations suitable to local needs and resources, and which provides illustrative models for use. A consideration of earlier efforts at curriculum renewal endowed some of our discussion with an uneasy sense of déjà vu. However, we hope that current insights from linguistics, psychology, and associated disciplines have provided a principled basis for some workable suggestions to inform and rejuvenate curricular practices. English does not stand alone. It needs to find its place 1. along with other Indian languages    i. in regional-medium schools: how can children’s other languages strengthen English teaching/learning?    ii. in English-medium schools: how can other Indian languages be valorised, reducing the perceived hegemony of English? 2.  in relati...

Writing Skill

4.1. What is writing? Writing is a form of communication that allows students to put their feelings and ideas on paper, to organize their knowledge and beliefs into convincing arguments, and to convey meaning through well-constructed text. In its most advanced form, written expression can be as vivid as a work of art. As children learn the steps of writing, and as they build new skills upon old, writing evolves from the first simple sentences to elaborate stories and essays. Spelling, vocabulary, grammar, and organization come together and grow together to help the student demonstrate more advanced writing skills each year. Writing is a medium of human communication that represents language and emotion through the inscription or recording of signs and symbols. In most languages, writing is a complement to speech or spoken language. Writing is not a language but a form of technology that developed as tools developed with human society. Within a language system, writing relies on m...
