Respiratory System Structures
What is the tube that carries air from the throat to the lungs?
What is Trachea / windpipe
Air enters the body through which two openings?
What is Nose and mouth?
What gas moves from the air sacs into the blood?
What is Oxygen?
What type of blood cell carries oxygen around the body?
What is Red blood cell?
What test is used to show that carbon dioxide is present?
What is Limewater Test?
What are the two tubes that branch from the trachea into the lungs called?
What is Bronchi?
After air passes through the trachea, where does it go next?
What is Bronchi?
What gas moves from the blood into the air sacs?
What is Carbon Dioxide?
What substance inside red blood cells carries oxygen?
What is Haemoglobin?
What happens to limewater when carbon dioxide is present?
What is It turns cloudy/milky?
What are the tiny air sacs at the end of bronchioles called?
What is Alveoli / air sacs?
What are the smaller branches inside the lungs called?
What is Bronchioles?
What process moves gases from an area of high concentration to low concentration?
What is Diffusion?
Where does oxygen go after it enters the blood?
What is To body cells?
Does expired air contain more or less carbon dioxide than inspired air?
What is More carbon dioxide?
What structure contains the vocal cords and helps us make sound?
What is Larynx / voicebox?
Put these in order: bronchioles, trachea, air sacs, bronchi.
What is Trachea → bronchi → bronchioles → air sacs?
Why do air sacs have very thin walls?
What is to allow gases to diffuse quickly?
Why do body cells need oxygen?
What is they need oxygen for respiration to release energy from food/glucose?
Why does expired air contain more water vapour than inspired air?
What is Air picks up moisture from the lungs and airways?
What strong but flexible rings keep the trachea open?
What is Cartilage rings?
Why is the respiratory system shaped like a branching tree?
What is to carry air deeper into the lungs and reach many air sacs?
Why are air sacs surrounded by many capillaries?
What is to allow oxygen and carbon dioxide to exchange easily with the blood?
Explain how the blood connects gas exchange in the lungs with respiration in body cells.
What is Blood picks up oxygen from the air sacs and carries it to body cells. Body cells use oxygen to release energy from food during respiration. Carbon dioxide is produced as waste and carried back by the blood to the lungs to be breathed out?
In a lung model, what does the balloon at the bottom represent?
What is the diaphragm?
