The Respiratory System

The Respiratory System

Success Criteria

• I will be able to describe the thorax, including ribs, intercostal muscles, diaphragm, trachea, bronchi, bronchioles, alveoli and pleural membranes

Multiple Choice

During exhalation, the ribs become depressed as the intercostal muscles relax - Thus the lung volume decreases which increases the alveolar pressure. What does this cause?

• Air flows from the area of lower pressure in the alveoli to the area of higher pressure in the atmosphere

• Air flows from the area of higher pressure in the alveoli to the area of lower pressure in the atmosphere

Multiple Choice

What pressure gradient is exhalation triggered by?

• The pressure in the lungs is less than the pressure of the atmosphere

• The pressure in the lungs is greater than the pressure of the atmosphere

Multiple Choice

What happens when the intercostals contract during inhalation?

• The diaphragm relaxes

• The ribs are elevated

• Pressure in the lungs increases

• The size of the thoracic cavity decreases

Multiple Choice

A contraction of the diaphragm during inhalation causes it to flatten. What else does the contraction result in?

• An increase in the volume of the thoracic cavity

• Increase in alveolar pressure

• A decrease in lung volume

• A decrease in the volume of the thoracic cavity

Multiple Choice

What are the main muscles of inhalation?

• The diaphragm and intercostal muscles

• The scalenes and the abdominal muscles

• The diaphram and abdominal muscles

• The diaphragm and latissimus muscles

Multiple Choice

When air pressure inside the lungs is less than air pressure in the atmosphere...

• Air moves into the lungs
• Air moves out of the lungs

Multiple Choice

Your lungs are sealed within air tight bags lined with something called the ..................... ..........................

• ciliated epithelium

• pleural membrane

• alveoli sacs

• intercostal muscle

Multiple Choice

Choose the correct air pathway when you breathe in.

• Windpipe ---> Nose ---> Lungs

• Nose ---> Windpipe ---> Lungs
• Nose ---> Lungs ---> Windpipe

Multiple Choice

Multiple Choice

Which image represents the respiratory system?

Multiple Choice

What is the function of the "Bronchioles"

Multiple Choice

What is the function of the "Bronchi"

• They are infinte braches of the trachea and carry air to the lungs

• They are one braches of the trachea and carry air to the lungs

• They are three braches of the trachea and carry air to the lungs

• They are two braches of the trachea and carry air to the lungs

Multiple Choice

What is the function of the "Lungs"

• Allows oxygen to be draw into the body ad carbon dioxide to be released out of the body

• The father and mother of the heart
