Transport Test Retake - Ethan Weston

How does breathing contribute to the body's internal balance?

• It removes waste through the kidneys

• It supplies oxygen and removes carbon dioxide

• It circulates nutrients

• It triggers nerve signals

Which group correctly lists only respiratory system organs?

• Heart, arteries, capillaries

• Lungs, nose, trachea

• Stomach, liver, intestines

• Brain, spinal cord, nerves

What is the primary role of the respiratory system?

• Generating energy for cells

• Facilitating the exchange of oxygen and carbon dioxide

• Breaking down nutrients

• Circulating nutrients throughout the body

The nasal cavity plays a key role in the respiratory process by:

• Filtering and moistening incoming air

• Absorbing nutrients

• Producing digestive enzymes

• Directing blood to the lungs

What is the primary purpose of the trachea?

• To provide a passage for air to reach the lungs

• To pump blood throughout the body

• To digest food

• To filter waste from the blood

Which of the following best describes one role of the larynx?

• It allows air and food to mix

• It directs blood flow to the lungs

• It contains the vocal cords and helps prevent choking

• It filters bacteria from food

Alveoli are specialized for:

• Circulating blood

• Digesting proteins

• Exchanging gases with capillaries

• Absorbing nutrients

Why must alveolar and capillary walls be thin?

• To support the lungs structurally

• To make room for mucus

• To allow gases to pass through efficiently

• To resist changes in pressure

The process of moving air in and out of the lungs depends on the:

• Skeletal system

• Muscular system

• Digestive system

• Integumentary system

The diaphragm relaxes and rises during exhalation.

• True

• False
