Respiratory Basics
This system allows animals to breathe
What is the respiratory system
This function allows oxygen to enter the body.
What is oxygen intake
What respiratory structure do mammals like horses and cattle use?
What are lungs
This is the first point of air entry into the respiratory system.
What is the nose or nasal cavity
This structure filters, warms, and moistens incoming air.
What is the nasal cavity
What gas is brought into the body during breathing?
What is oxygen (Oâ‚‚)
This function removes waste gases from the body.
What is carbon dioxide removal
What do fish use to obtain oxygen from water?
What are gills
After the nasal cavity, air moves into this shared passageway.
What is the pharynx
This flap prevents food from entering the airway.
What is the epiglottis
What waste gas is removed by the respiratory system?
What is carbon dioxide (COâ‚‚)
The respiratory system helps regulate this, especially during heat stress.
What is body temperature
Birds use lungs plus these structures to increase oxygen efficiency.
What are air sacs
This structure produces sound and keeps the airway open.
What is the larynx
These tiny air sacs are surrounded by capillaries
What are alveoli
This system works closely with the respiratory system to transport oxygen.
What is the circulatory system
The respiratory system helps maintain proper levels of this in the blood.
What is blood pH
What respiratory system do insects use?
What are tracheal tubes
This rigid tube with cartilage rings carries air to the lungs.
What is the trachea
Gas exchange occurs at this structure.
What are alveoli
Oxygen is required for this process that produces ATP in cells.
What is cellular respiration
This function allows animals to produce sounds.
What is vocalization
What type of lungs do reptiles have compared to mammals?
What are simple lungs
Put these structures in correct order: bronchi, alveoli, bronchioles.
What are bronchi → bronchioles → alveoli
This muscle controls breathing by contracting and relaxing.
What is the diaphragm
