After oxygen diffuses into the capillaries from the alveoli, where does the oxygen-rich blood go next?
Into the pulmonary veins and then to the heart
Into the pulmonary arteries and then to the lungs
Directly into the aorta
Into the bronchioles
Explain why the membranes of the alveoli are very thin. How does this structural feature support their function?
Thin membranes allow for faster diffusion of oxygen into the capillaries.
Thin membranes prevent bacteria from entering the lungs.
Thin membranes help trap dust particles.
Thin membranes make the lungs more flexible.
What is the primary function of the ribs in the lower respiratory system?
To help with digestion
To protect the lungs from getting punctured
To produce red blood cells
To filter air entering the lungs
Which cavity do the ribs help create, allowing for inhalation and exhalation?
Abdominal cavity
Cranial cavity
Thoracic cavity
Pelvic cavity
What is the role of the pleural membrane found in the ribs?
It produces oxygen for the lungs
It helps the ribs move during digestion
It is very slippery and reduces friction against the lungs
It stores nutrients for the body
Explain how the pleural membrane helps prevent damage to the lungs during breathing.
By producing mucus to trap dust
By creating a thin layer of fluid that reduces friction
By contracting to force air out
By absorbing carbon dioxide
Why is it important for the thoracic cavity to be airtight?
To keep the heart in place
To allow for expansion and contraction during breathing
To prevent food from entering the lungs
To increase blood flow to the lungs
What is the main function of the diaphragm in the lower respiratory system?
To increase the internal volume of the thoracic cavity during inhalation
To pump blood throughout the body
To digest food in the stomach
To filter waste from the blood
What happens to the thoracic cavity when the diaphragm relaxes and returns to its dome-like shape?
The thoracic cavity shrinks and air is pushed out
The thoracic cavity expands and air is pulled in
The thoracic cavity fills with blood
The thoracic cavity becomes rigid
Which of the following best describes the diaphragm?
A sheet of muscle that goes across the torso under the lungs
A bone that supports the rib cage
A gland that produces hormones
A nerve that controls breathing
Explain how the diaphragm contributes to the process of inhalation and exhalation.
When the diaphragm contracts and pulls flat, it increases the internal volume of the thoracic cavity, pulling in air (inhalation). When it relaxes and returns to its dome-like shape, the thoracic cavity shrinks and pushes air out (exhalation).
When the diaphragm contracts, it pushes food down the esophagus. When it relaxes, it helps the heart beat.
The diaphragm filters air before it enters the lungs and removes carbon dioxide.
The diaphragm stores oxygen for later use in the body.
Why is the pulmonary system particularly susceptible to infections?
Because it is one of the main ways for pathogens to enter the body.
Because it is not protected by the immune system.
Because it is not connected to other body systems.
Because it is always exposed to sunlight.
What does the abbreviation "URI" stand for in the context of the upper respiratory system?

Upper respiratory infection (URI)
Broken bone
Food poisoning
Skin allergy
What can happen if some upper respiratory infections (URI) migrate into the internal respiratory system?
They become a chest infection.
They cause immediate recovery.
They always remain harmless.
They turn into allergies.
Which of the following best describes how influenza differs from a typical upper respiratory infection (URI)?
Influenza only affects the respiratory system and never the digestive system.
Influenza often affects the digestive system, causing nausea and upset stomach, unlike a typical URI.
Influenza is not contagious, while a URI is.
Influenza is caused by bacteria, while a URI is caused by viruses.
Which of the following best describes asthma?
A condition where the muscles surrounding the bronchi overreact to stimuli, causing them to contract and making breathing out more difficult.
A condition where the heart beats irregularly due to electrical impulses.
A disease caused by bacteria infecting the lungs.
A disorder where the digestive system cannot process certain foods.
Why does asthma make breathing out more difficult?
Because the muscles around the bronchi contract, narrowing the airways.
Because the lungs fill with fluid.
Because the diaphragm stops working.
Because the nose becomes blocked.

Middle-aged adults
What is the main reason carbon dioxide builds up in the bloodstream of someone with emphysema?
The lungs produce too much carbon dioxide
The diaphragm is not strong enough to fully exhale
The person breathes in too much carbon dioxide
The blood cannot carry oxygen
Why might a person with emphysema act as if they have dementia?
Due to lack of sleep
Because of confusion caused by carbon dioxide buildup
Because of high oxygen levels
Due to dehydration
Why does a person with pneumonia have trouble getting enough air?
Because their lungs are filled with fluids, making it hard to breathe.
Because their lungs are filled with extra oxygen.
Because their lungs are not connected to the airway.
Because their lungs are too dry.
Explain how the inflammation and fluid buildup in the lungs during pneumonia can affect a person's ability to breathe.
The inflammation and fluid buildup reduce the space for air in the lungs, making it difficult for oxygen to enter the bloodstream.
The inflammation and fluid buildup increase the amount of oxygen in the lungs, making breathing easier.
The inflammation and fluid buildup have no effect on breathing.
The inflammation and fluid buildup make the lungs stronger.

Why might a doctor choose to use a stethoscope rather than just listening with their ear during a diagnosis?
A stethoscope allows for more specific listening to particular areas and frequencies of the lungs and heart.
A stethoscope is used to see inside the body.
A stethoscope is used to administer medication.
A stethoscope is used to take X-rays.
