WEEK 1 - Respiratory System

Welcome to Week 1 of our Science Class

for our lesson we will talk about the RESPIRATORY SYSTEM.

LET US TAKE A TRIP TO THE WORLD OF THE RESPIRATORY SYSTEM. SO...

​BEGIN

​Your body is a fascinating creation that can carry out incredible tasks and activities. It is like a machine that is able to function with proper organization of parts and systems.

​

However, our bodies also require proper care and maintenance. It is just fitting to keep going with a healthy lifestyle to ensure that each part is maintained appropriately while getting the most of it.

Respiratory system is made up of organs in the body that help us to breathe.

​

Just remember that respiration is linked to breathing.

​Getting to know the respiratory system helps us understand our body better. Read on and perform the activities prepared for you in this module.

At the end of the module, you should be able to:

1. ​Define respiration operationally

2. Differentiate the internal and external respiration.

3. Identify the parts of respiratory system

4. Explain the function of the different organs

​Hi! How did you find the Activity 1?

​

Don’t worry if you got a low score, this just means that there are more things that you can learn from this module.

​

So, hop on!

Animal cells generate ATP in aerobic respiration, which consumes O2 and generated CO2 as a waste product.

• Respiration is the physical movement of air into and out of the body.

• Respiration is the act of exchanging gases.

• External respiration is gas exchange between an organism’s body and its environment; internal respiration is gas exchange between tissue cells and the bloodstream.

• Respiration is the movement of air or dissolved gases into and out of the lungs or movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.

​ACTIVITY 2 - DEFINE ME

Directions: Read the questions carefully and choose the letter of the correct answer.

Multiple Choice

Which is the correct definition of respiration?

• Respiration is the act of exchanging gases.

• Respiration is the act of using carbon dioxide and producing oxygen as a waste product.

Multiple Choice

Internal respiration is .....

• the gas exchange between an organism’s body and its environment

• the gas exchange between tissue cells and bloodstream

• The parts of the respiratory system that are in charge of supplying oxygen are the nose, nasal passageways, windpipe, lungs, and diaphragm.

• In the nose and nasal passages, the entering air is made warm, damp, and clean of unknown particles.

• Next, the air moves down through the trachea, bronchi, bronchioles, and alveoli.

Trachea is the empty tube that serves as passageway of air into the lungs.

​

Bronchi are the two branching tubes that connect the trachea to the lungs.

​

Bronchioles are the hair like tubes that connect to the alveoli.

Alveoli are the air sacs that allow gas exchange in the lungs.

​ACTIVITY 3 - WHAT A BUNCH OF GRAPES!

Directions: Use the figure in the next slide to answer the questions.

Multiple Choice

What does the MAIN STEM of the “Bunch of Grapes” model represent, in relation to the breathing system?

• BRONCHI

• TRACHEA

• BRONCHIOLES

• ALVEOLI

Multiple Choice

What does the LARGE BRANCHING STEM of the “Bunch of Grapes” model represent, in relation to the breathing system?

• BRONCHI

• TRACHEA

• BRONCHIOLES

• ALVEOLI

Multiple Choice

What does the LITTLE STEM of the “Bunch of Grapes” model represent, in relation to the breathing system?

• BRONCHI

• TRACHEA

• BRONCHIOLES

• ALVEOLI

Multiple Choice

What does the INDIVIDUAL GRAPES of the “Bunch of Grapes” model represent, in relation to the breathing system?

• BRONCHI

• TRACHEA

• BRONCHIOLES

• ALVEOLI

Multiple Choice

What will happen if one part of the system fails to carry out its function properly?

• it will not function anymore or there will be a difficulty in breathing

• it will function normally

• nothing will happen

• All of the above

​ACTIVITY 4 - LABEL ME

Multiple Choice

How do you describe the pathway of oxygen in the breathing system?

• It starts with the nose to the trachea. Then it moves to the bronchi, to the alveoli until it moves to the lungs.

• It starts with the nose to the trachea. Then it moves to the bronchi, to the bronchioles until it moves to the alveoli.

• It starts with the trachea to the nose. Then it moves to the bronchi, to the bronchioles until it moves to the alveoli.

• It starts with the nose to the trachea. Then it moves to the bronchioles, to the bronchi until it moves to the alveoli.

Multiple Choice

What is inhalation?

• Inhalation is the process by which air (oxygen) moves inside the body.

• Inhalation is the process by which air (CO2) moves inside the body.

Multiple Choice

What is exhalation?

• Exhalation is the process by which air (oxygen) moves outside the body.

• Exhalation is the process by which air (CO2) moves outside the body.

​You have just had an amazing learning journey and for sure, you will have the same in the succeeding modules.

• This time, share to the class your final insights by completing the following sentence prompts.

I wish to ask my teacher about...

​WORD BANK

​1. Trachea - also called windpipe; a hollow tube that serves as passageway of air into the lungs

2. Bronchi - also called bronchial tubes; two branching tubes that connect the trachea to the lungs

3. Nose – the organ through which the air enters and is filtered

​WORD BANK

4. Nasal passages – serve as channel for airflow through the nose in which the air is warmed, cleaned, and moistened.

5. Bronchioles - the finer subdivisions of the bronchi; hairlike tubes that connect to the alveoli

6. Alveoli - also called airsacs; allow the gas exchange in lungs.

​WORD BANK

7. The air we breathe goes through the nose, nasal passages, and then through the trachea or windpipe, which separates into two branches, called bronchial tubes or bronchi, one entering each lung.

​WORD BANK

8. The bronchi subdivide many times inside the lungs, analogous to the branching pattern of grapes, finally becoming hairlike tubes called bronchioles. In the last part of the terminal bronchioles are tiny bubble – like bunch structures called alveoli or airsacs.

​WORD BANK

9. Inhaling moves the diaphragm down and expands the chest cavity. Simultaneously, the ribs move up and increase the size of the chest cavity. There is now more space and less air pressure inside the lungs. Air pushes in from the outside where there is higher air pressure. It pushes into the lungs where there is lower air pressure.
