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

• Circulatory system

• Nervous System

• Respiratory System

• Excretory System

Which of the following is the function of alveoli?

• It filters the air we breathe.

• It serves as the entrance of air to the lungs.

• It carries oxygen in and out the lungs

• It allows gas exchange inside the lungs.

Which of the following describes bronchial tubes?

• They connect the trachea to the lungs.

• They filter the air that we inhale.

• They facilitate the exchange of gases inside the lungs.

• They are hair-like tubes that connect to the alveoli.

Air that enters the air sacs after inhaling is rich in _______ gas.

Which of the following DOES NOT describe inhalation

• The diaphragm muscle relaxes

• The ribs move up and increase the size of the chest cavity

• More space and less air pressure inside the lungs

• The diaphragm moves down and expands the chest cavity.

What will happen if there are more space and less air pressure inside the lungs?

• Air pushes in from the outside towards the lungs where there is less air pressure

• Air pulled out from the lungs towards the outside where there is a higher air pressure

• Air will be flushed out from the lungs where there is a higher pressure

• Air will be maintained inside the lungs

Which of the following describes exhalation?

• The ribs are moved up and increase the size of the chest cavity

• There will be more space and lesser air pressure inside the lungs

• There will be less space and greater air pressure inside the lungs

• The diaphragm moves down and expands the chest cavity

The circulation of blood from the heart, to the lungs, and back to the heart is called:

Which of the following BEST describes the mechanism of how the respiratory and circulatory systems work together?

• The heart pumps the blood that transports the inhaled oxygen to every cell of the body. Carbon Dioxide is then carried by the blood to the lungs and is released through exhalation.

• The blood from the heart carries deoxygenated blood to the cells of the body and then transport oxygenated blood to the lungs for exhalation.

• The lungs will collect oxygen and then transport it to the heart, the heart will then distribute it to its four chambers then transport it back to the lungs.

• The respiratory and circulatory system both inhale oxygen and release carbon dioxide through exhalation.

It is the life support structure that nourishes your cells with food and oxygen.

• Respiratory System

• Circulatory System

• Nervous System

• Digestive System
