What are the functions of the respiratory system?

• Break down food into minerals and nutrients our body can use

• Bringing oxygen to our cells and removing carbon dioxide from our cells

• Bringing oxygen to our blood and removing carbon dioxide from our blood

• Pumping blood through our body

The name of the organ that picks up oxygen from inhaled air and passes carbon dioxide into the exhaled air is called ________.

• Bronchi

• Nasal Cavity

• Larynx

• Lungs

At what structures in the lungs do the exchange of oxygen and carbon dioxide take place?

• Bronchi

• Alveoli

• Bronchioles

• Trachea

In which part of the respiratory system do the gaz exchanges take?

• in the trachea

• in the nasal passages

• in the alveoli

• in the bronchi

• in the bronchioles

There are different muscles helping during breathing. One is the diaphragm and the others are intercostal muscles. Where are the intercostal muscles?

• under the lungs

• between the ribs

• on top of the lungs

• in your throat

Which part of the respiratory system is a strong, curved muscle attached below the lungs to the lower ribs and backbone?

• the alveoli

• the diaphragm

• the cilia

• the epiglottis

What is the function of the bronchi?

• Transport air from nose to lungs

• Transport air from trachea to lungs

• Transport air from lungs to alveoli

• Transport air from alveoli to blood

What is the diaphragm's main function?

• pump blood into the lungs

• pump oxygen out of the lungs and pull carbon dioxide into the lungs

• pumping blood

• pump carbon dioxide out of the lungs and pull oxygen into the lungs

Why is the left lung slightly smaller than the right lung ?

• to give space for the heart

• to breathe easily

• to give space for the stomach

• to swallow easily

Inside each of your lungs, there are tubes called bronchi. These branch into even smaller tubes, much like the branches of a tree. What are at the ends of these tubes?

• Alveoli

• Diaphragm

• Cells

• capillaries
