READING COMPREHENSION PRACTICE 8

1.

Our lungs are important organs that help us breathe.

When we inhale, or breathe in, air enters through our nose and mouth,

travels down our windpipe, and fills our lungs.

Inside the lungs, there are tiny air sacs called alveoli.

Where do we find tiny air sacs?

• in our mouth

• in our nose

• in our lungs

• in our windpipe

2.

1) These sacs are like little balloons that let oxygen from the air pass into our blood.

2) At the same time, they help remove carbon dioxide, which is a gas our body doesn’t need anymore.

In which line do we find a simile?

• line 1

• line 2

3.

When we exhale, or breathe out, our body releases carbon dioxide back into the air.

This process is essential for maintaining the balance of gases in our environment.

What happens to carbon dioxide when we exhale?

• It is absorbed by the lungs

• It is stored in the blood

• It is converted to oxygen

• It is released into the air

4.

The diaphragm is a muscle that plays a crucial role in breathing.

When it contracts, it creates a vacuum that pulls air into the lungs.

When it expands, the air is released outside the lungs.

What role does the diaphragm play in breathing?

• It creates a vacuum for air movement

• It helps to filter the air

• It stores oxygen

• It removes carbon dioxide

5.

Asthma is a condition that affects the airways in the lungs, making it difficult to breathe.

People with asthma may experience wheezing and shortness of breath.

To take care of them, we should ensure windows are always open

to let in fresh air everywhere in our buildings.

What is a common symptom of asthma?

• Deep breaths

• Clear breathing

• Wheezing

• Increased energy
