The presentation "respiratory system" was prepared for grade VI. this presentation includes short evaluation test in the end, for assessing the learning of students from this. the presentation is according to the syllabus of Usman Public School System, Pakistan.
It is a powerpoint presentation that discusses about the lesson or topic: Respiratory System. It also talks about the definition, parts and the concepts about Respiratory System.
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

Respiration Process which involves taking in oxygen into the cells, using it for releasing energy by burning food and then eliminating the waste products like carbon dioxide and water from the body It is a catabolic process as the food is broken down into simpler form. In short, respiration is a biochemical activity taking place with in the protoplasm of the cell and results in the liberation of energy
2. Breathing and Respiration BREATHING 1. Mechanism by which organisms obtain oxygen from the air and release carbon dioxide 2. It is a physical process 3. It involves lungs of the organism RESPIRATION 1. It includes breathing and oxidation of food in the cells of the organism to release energy 2. It is a biochemical process 3. It involves the mitochondria in the cells where food is oxidized to release energy
The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory system, such as an infection like pneumonia, it makes it harder for us to get the oxygen we need and to get rid of the waste product carbon dioxide. Common respiratory symptoms include breathlessness, cough, and chest pain.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
2. Can you count that
how many times
you breath in 1
minute?
Now multiply it by
1440.
This is the number of
times you breath in
and out in a day.
3. “Physiologically, Respiration is
the transport of oxygen from
the outside air to the cells
within the transport of
carbon dioxide in the
opposite direction.”
4. “Chemically respiration is the
metabolic process by which an
organism obtains energy by
reaction of oxygen with glucose
to give water, carbon dioxide
and energy.”
17. Air can also enter through nasal passage
It is a hollow passage.
It is lined with mucous membrane,
which bears tiny hairs.
Then air enters trachea
18. FUNCTIONS OF THE NOSE:
1. Filter the air.
2. Warm the air.
3. Moisten the air.
4. The tiny hairs trap the dust particles
5. These hairs also induce sneezing to
remove foreign bodies.
19. Air enters our
body through
mouth OR nose.
Mouth opens into
pharynx OR
throat.
Opening of
nostrils into
pharynx is guided
by soft palate.
20. Pharynx leads to larynx
through an opening
called glottis.
Glottis is guarded by an
opening called
epiglottis.
FUNCTIONS OF LARYNX:
Larynx is responsible in
the production of voice,
through a small chamber
called VOICE BOX.
21. Trachea or windpipe begins just below the
larynx.
Trachea is lined with a mucous membrane
It have hair like projections called CILIA.
FUNCTIONS:
1. The mucous traps dust and bacteria from
the incoming air.
2. Cilia moves the mucous upward to clear the
respiratory tract.
22. It is a flap In the throat that blocks the
windpipe when food or liquid is being
swallowed.
23.
24. Trachea divides into
two bronchi
They are tubes that
carry air to the lungs
Each bronchi goes in
each lung.
The walls produce
mucous which is
moved upward by the
cilia to clear the
passage.
25. Each bronchus divide into further smaller
tubes, called bronchioles.
There are thousands of bronchioles.
At the end of each bronchiole is an air sac.
26. At last bronchioles enter tiny sac like
structures called ALVEOLI.
Alveoli are tiny, stretchy sacs.
They have thin moist wall.
They blow up like balloons when we breath in
There are about 300 million Alveoli in your
lungs.
27.
28. Alveoli are covered with narrow blood
vessels called Capillaries.
The alveoli increase the surface area of the
lings and allow many blood vessels to collect
oxygen.
Here, Oxygen passes into blood in the
capillaries, through the walls of alveoli.
This transfer process of oxygen is calle
Diffusion.
29.
30.
31. Pair of lungs (2 lungs).
Balloons like structure.
In the chest, protected by rib cage
Gas exchange take place here.
33. Each lung is protected by two thin
membranes called as Pleural
Membranes.
Within the two membranes is a fluid
filled cavity called pleural cavity.
34.
35. Diaphragm is a strong muscle, just below the
lungs.
When you breath in, the diaphragm moves down.
When you breath out, the diaphragm moves up.
Fish breathe with their GILLS.
Fish use these gills to take in oxygen from their watery environment. When fish open and close their mouths, this is how they breathe.
