The Respiratory System:

It'll Take Your Breath Away

Diaphragm

• Allows you to move food throughout your thoracic cavity.

Multiple Choice

The gas known as _______ is needed for humans to stay alive. Without this gas inside of our bodies, the respiratory system could not function properly.

• nitrogen

• carbon dioxide

• oxygen

• helium

Multiple Choice

What is the main function of the respiratory system?

• to provide oxygen and remove carbon dioxide from the body

• to remove oxygen from the body and deliver carbon dioxide

• to break down food and absorb nutrients

Multiple Choice

The two main jobs of the Respiratory System are

• Chewing and swallowing food

• Sending blood through veins and arteries

• Inhaling oxygen and exhaling carbon dioxide

• Protecting and comforting your Shiv Patella

The respiratory system is the network of organs and tissues that help you breathe. The respiratory system is the network of organs and tissues that help you breathe.

The respiratory system has many functions. Besides helping you inhale (breathe in) and exhale (breathe out), it:

• Allows you to talk and to smell.

• Warms air to match your body temperature and moisturizes it to the humidity level your body needs.

• Delivers oxygen to the cells in your body.

• Removes waste gases, including carbon dioxide, from the body when you exhale.

• Protects your airways from harmful substances and irritants.

The respiratory system has many different parts that work together to help you breathe. Each group of parts has many separate components.

​What are the Parts of the Respiratory System?

• Mouth and nose: Openings that pull air from outside your body into your respiratory system.

• Sinuses: Hollow areas between the bones in your head that help regulate the temperature and humidity of the air you inhale.

• Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe).

• Trachea: Passage connecting your throat and lungs.

• Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung.

• Lungs: Two organs that remove oxygen from the air and pass it into your blood.

• Diaphragm: Muscle that helps your lungs pull in air and push it out.

• Ribs: Bones that surround and protect your lungs and heart.

It is the network of organs and tissues that help you breathe.

• digestive system

• nervous system

• circulatory system

• respiratory system

Multiple Choice

What is the purpose of the respiratory system?

• takes in oxygen and releases nitrogen

• takes in carbon dioxide and releases oxygen

• takes in oxygen and releases carbon dioxide

• takes in nitrogen and releases oxygen

Multiple Choice

A __________ is triggered by an irritation in the nose.

• cold

• cough

• sneeze

• snore

Multiple Choice

What is the scientific name for the windpipe?

• bronchial

• esophagus

• trachea

• alveoli

Multiple Choice

Where do arteries carry blood so it can be cleaned of carbon dioxide?

• the kidneys

• the lungs

• the heart

• the stomach

Multiple Choice

Where is carbon dioxide and oxygen exchanged in the lungs?

• alveoli

• villi

• nephrons

• urethrae

Multiple Choice

We breathe in _____& breathe out ______.

• oxygen, carbon dioxide

• carbon dioxide, oxygen

Multiple Choice

What is the 1st step in the Respiratory system

• mouth

• nose

• mouth & nose

• the eye

Multiple Choice

The Main tube that takes air to your lungs

• bronchi

• bronchioles

• trachea

• air sacs

Multiple Choice

The tubes that lead into each lung

• trachea

• bronchi

• bronchioles

• air sacs

Multiple Choice

What is the Scientific Name for Air Sacs

• bronchi

• alveoli

• bronchioles

• trachea

Multiple Choice

Large, dome like muscle under your lungs

• Lungs

• Trachea

• Diaphragam

• Alveoli

Multiple Choice

The main function of the respiratory system is to supply oxygen to the body.

• true

• false

Multiple Choice

What are the lungs getting rid of when you exhale?

• Air
• Oxygen
• Carbon Dioxide
• Nitrogen

Multiple Choice

What are the main organs in the Respiratory System?

• Windpipe

• Nose

• Mouth

• Lungs

Multiple Select

What are the two openings that bring air into your body?

• Mouth

• Lungs

• Nose

• Sinus

The bronchioles eventually end in clusters of microscopic air sacs called alveoli. In the alveoli, oxygen from the air is absorbed into the blood. Carbon dioxide, a waste product of metabolism, travels from the blood to the alveoli, where it can be exhaled.
