Multiple Choice

Which of the following is a primary function of the respiratory system?

• Digesting food

• Transporting blood

• Exchanging gases between the body and the environment

• Producing hormones

Multiple Choice

Which of the following best describes the main difference between respiration by the respiratory system and cellular respiration?

• Respiration by the respiratory system involves gas exchange between the body and atmosphere, while cellular respiration occurs inside cells to produce energy.

• Respiration by the respiratory system produces glucose, while cellular respiration uses glucose.

• Cellular respiration occurs in the lungs, while respiration by the respiratory system occurs in the blood.

• Respiration by the respiratory system removes oxygen from the body, while cellular respiration adds oxygen to the body.

Open Ended

Why is it important for the respiratory system to protect itself from pathogens and harmful substances in the air?

Open Ended

Explain how the processes of ventilation and gas exchange work together in the respiratory system.

Multiple Select

Which of the following are parts of the lower respiratory tract?

• Trachea

• Primary bronchi

• Lungs

• Pharynx

Open Ended

What are the main functions of the upper respiratory tract organs?

Multiple Choice

Which of the following is NOT a function of the nasal cavity?

• Warming and humidifying inhaled air

• Trapping large foreign particles

• Producing sound for speech

• Contributing to the sense of smell

Multiple Choice

Which structure serves as a passageway for both air and food, making it part of both the respiratory and digestive systems?

• Pharynx

• Trachea

• Larynx

• Esophagus

Multiple Choice

Which of the following is NOT a function of the larynx?

• Conducting air through the respiratory tract

• Producing vocal sounds

• Protecting the trachea from aspirated food

• Digesting food

Multiple Choice

What is the main function of the bronchi in the respiratory system?

• To carry air between the trachea and lungs

• To exchange gases with capillaries

• To secrete surfactant

• To separate the lungs into lobes

Multiple Select

Which of the following statements about the blood supply to the lungs are correct?

• The lungs receive deoxygenated blood from the right side of the heart.

• Oxygenated blood is supplied to the lungs for cellular respiration.

• Blood in the lungs absorbs oxygen and returns to the left side of the heart.

• The lungs only receive blood from the left side of the heart.

Multiple Select

Which of the following statements about the lungs are correct?

• The lungs are suspended within the pleural cavity of the thorax.

• The right lung contains three lobes.

• The left lung is larger than the right lung.

• The lungs are surrounded by two thin membranes called pleura.

Multiple Choice

Why is it important to sneeze into a tissue rather than into the air?

• To prevent the transmission of respiratory pathogens

• To increase the force of the sneeze

• To avoid irritating the nasal passage

• To help the body absorb more oxygen

Multiple Choice

What is the primary function of alveoli in the lungs?

• Gas exchange between air and blood

• Filtering dust from inhaled air

• Producing mucus to trap pathogens

• Pumping blood throughout the body

Open Ended

Describe how the respiratory system helps maintain homeostasis in the body, particularly in relation to blood gases and pH.

Multiple Choice

Which structures branch from the main bronchi and eventually terminate in alveolar sacs?

• Bronchioles

• Trachea

• Pleura

• Lobes

Multiple Choice

Which of the following is a key function of the respiratory system?

• Transporting nutrients to cells

• Protecting the body from pathogens in the air

• Digesting food

• Producing hormones
