The process of exchanging oxygen and carbon dioxide in the lungs is called ___.

Multiple Choice

Which organ is primarily responsible for the exchange of oxygen and carbon dioxide in the human body?

• Lungs

• Heart

• Kidneys

• Liver

Open Ended

How do we differentiate breathing from respiration?

Multiple Choice

Which of the following best describes the main difference between breathing and respiration?

• Breathing is the act of taking air in and out of the lungs, while respiration is the overall exchange of gases in the body.

• Breathing and respiration are exactly the same processes.

• Respiration only occurs in the lungs, while breathing occurs in all body cells.

• Breathing is a chemical process, while respiration is a physical process.

Multiple Choice

Why do earthworms use their body surface for respiration?

• Because their capillaries come close to the surface.

• Because they have lungs like mammals.

• Because their skin is dry and thick.

• Because they do not need oxygen.

Multiple Choice

Which respiratory surface is used by insects to deliver oxygen directly to their cells?

• Gills

• Lungs

• Spiracles

• Skin

Multiple Choice

Which of the following statements about lungs is correct?

• Lungs directly contact all parts of the body for gas exchange.

• Lungs contain internal respiratory surfaces and require the circulatory system for gas exchange.

• Lungs are found only in invertebrates.

• Lungs extract oxygen from water only.

Open Ended

Compare the respiratory surfaces used by aquatic vertebrates and terrestrial vertebrates.

What are the main differences in their structure and function?

Open Ended

Explain the role of the diaphragm and intercostal muscles during inspiration and expiration.

Multiple Choice

Which of the following changes occur during inhalation?

• Diaphragm relaxes, thoracic cavity reduces

• External intercostal muscles contract, thoracic cavity expands

• Air is forced out of the lungs

• Rib cage recoils

Multiple Choice

Which respiratory pigment contains copper instead of iron and gives blood a blue coloration when oxygenated?

• Hemoglobin

• Haemocyanin

• Chlorocruorin

• Haemerythrin

Fill in the Blank

What are the common diseases associated with the respiratory system? Describe it briefly.

Multiple Choice

Bronchial tubes contract quickly causing shortness of breath, coughing, and wheezing

• Bronchitis
• Emphysema
• Lung cancer
• Asthma

Multiple Choice

Asthma is a respiratory disorder characterized by:

• Excessive production of mucus

• Narrowing of the airways

• Infection of the alveoli

• Collapse of the lung

Multiple Choice

Which of the following is a classic symptom of asthma in children?

• Frequent urination

• Wheezing

• Rash

• Diarrhea

Multiple Choice

Which of the following is NOT a symptom of the common cold?

• Coughing

• Sneezing

• Rash

• Sore throat

Multiple Choice

Which of the following is a common cause of chronic obstructive pulmonary disease (COPD)?

• Viral infection

• Smoking

• Genetic mutation

• Allergic reaction

Multiple Choice

Emphysema, a type of COPD (Chronic Obstructive Pulmonary Disease), leads to:

• Thickening of the alveolar walls

• Increased number of alveoli

• Destruction of alveolar walls

• Decreased mucus production

Multiple Choice

What is the effect of smoking on the respiratory system?

• It increases lung capacity

• It enhances the efficiency of gas exchange

• It damages the cilia in the respiratory tract

• It increases the production of surfactant

Multiple Choice

Pneumonia in infants can be caused by:

• Bacteria only

• Viruses only

• Both bacteria and viruses

• Neither bacteria nor viruses

Multiple Choice

Tuberculosis is a disease that primarily affects the:

• Heart

• Lungs

• Liver

• Kidneys

Multiple Choice

Pneumonia affects the lungs in which of the following ways?

• By causing the airways to narrow and making it hard to breathe

• By filling the alveoli with fluid or pus, making gas exchange difficult

• By hardening the alveoli, making them less elastic

• By reducing the capacity of the blood to carry oxygen

Multiple Choice

Which of the following statements is true regarding the treatment of cold and flu?

• Antibiotics are effective against both cold and flu viruses.

• Antiviral medications can be used to treat the flu, but not the common cold.

• Over-the-counter medications can cure both cold and flu.

• Cold and flu viruses can be treated with the same vaccine.

Multiple Choice

Pulmonary fibrosis affects the lungs by:

• Increasing the efficiency of gas exchange

• Causing the overproduction of mucus

• Thickening and scarring the lung tissue

• Expanding the airways

Multiple Choice
