Which of the following best describes the function of the alveolus (alveoli)?
The alveoli contract and work like a vacuum to pull air into the lungs.
The alveoli are tiny sacs where gas exchange occurs by diffusion of gases.
The alveoli are passageways that allow air to travel from the nasal cavity to the pharynx
The alveoli are a movable flap that covers the throat to prevent food and drink from entering.
Which structures are responsible for contracting to help air come into the lungs?
The ribcage and trachea
The trachea and larynx
The nasal cavity and oral cavity
The diaphragm and intercostal muscles
Which process allows for gas exchange in the alveoli?
Diffusion of molecules
Cellular respiration
Muscle contractions
Photosynthesis
Oxygen is needed by cells to produce ATP. During this process, carbon dioxide is created as a byproduct. Which biological process is responsible for the chemical conversion of oxygen to carbon dioxide.
Diffusion of molecules
Cellular respiration
Muscle contraction
Photosynthesis
