 Life Processes - Pathway of Air
(Breathing Process)

CBSE Class 10 - Science - Biology

Breathing process involves a the pathway of air from nostril to alveolus. It is a physical process. The pathway is described as follows:

Nostrils:         ⇅	Air usually enters the body through the nostrils.
Nasal cavity: ⇅	Air is filtered. The moist surface of the lining of the nasal cavity, and the hairs growing from its sides, remove some of the tiny particles of dirt in the air. In addition, as the inhaled air passes through the nasal cavity, its temperature is brought close to that of the body, and it takes up water vapour so that it becomes more moist than before.

CBSE Class 10/9/8 - English - Reading Comprehension (Unseen Poem - 3) (#cbseNotes)

Reading Comprehension (Unseen Poem - 3)

Question: Read the poem below:

When storm‐clouds rumble in the sky and
June showers come down
The moist east wind comes marching over the heath
to blow its bagpipes amongst the bamboos
The crowds of flowers come out of a sudden
from nobody knows where,
and dance upon the grass in wild glee.

Mother, I really think the flowers go to school underground
They do their lessons with doors shut,
and if they want to come out to play before it is time,
their master makes them stand in a corner.
When the rains come they have their holidays.

Branches clash together in the forest
and the leaves rustle in the wild wind,
the thunder‐clouds clap their giant hands and
the flower children rush out in dresses of
pink, yellow and white.

Do you know, mother, their home is in the sky,
Where the stars are.

Haven’t you seen how eager they are to get there ?
Don’t you know why they
are in such a hurry ?
Of course, I can guess to whom they raise their arms
they have their mother
as I have my own .

‐Rabindranath Tagore
