Respiration

What is the process by which organisms obtain the energy needed to drive the chemical processes in their cells?

• Photosynthesis

• Respiration

• Digestion

• Circulation

Where is the oxygen needed for respiration obtained from in humans?

• Gaseous exchange in the lungs

• Gaseous exchange in the stomach

• Gaseous exchange in the liver

• Gaseous exchange in the brain

What are the main parts of the respiratory system in humans?

• Nose, mouth, and lungs

• Heart, liver, and kidneys

• Stomach, intestines, and bladder

• Brain, spinal cord, and nerves

What is the function of the diaphragm in the respiratory system?

• To support the trachea and bronchi

• To protect the lungs from pollution

• To increase the volume of the thoracic cavity during inhalation

• To decrease the volume of the thoracic cavity during exhalation

What happens to the air pressure in the thoracic cavity during inhalation?

What is the composition of exhaled air compared to inhaled air?

• More oxygen, less carbon dioxide

• More carbon dioxide, less oxygen

• More water vapor, less nitrogen

• More nitrogen, less water vapor

What is the purpose of a ventilator machine?

What is the purpose of testing for carbon dioxide in exhaled air?

• To determine lung capacity

• To measure oxygen levels

• To assess respiratory health

• To confirm the presence of exhaled air
