Biology respiratory system
What is the primary function of the respiratory system?
To exchange gases such as oxygen and carbon dioxide
What structure in the respiratory system is responsible for gas exchange?
Alveoli
Which muscle helps in the process of breathing?
Diaphragm
Which part of the respiratory system is also known as the voice box?
Larynx
What prevents food from entering the windpipe during swallowing?
Epiglottis
What is the primary gas exhaled by the human respiratory system?
Carbon dioxide
Where does air enter the respiratory system?
Through the nose and mouth
What are the small branches of the bronchi called?
Bronchioles
Which respiratory condition is caused by the constriction of airways?
Asthma
Which gas is essential for cellular respiration and is taken in through the respiratory system?
Oxygen
function of cilia
beat to move mucus and debris up and into the trachea so it can be swallowed and destryed in stomach
whats a cilia
small hair like projections that move mucus and debris out of the peripheral
adaptation of alveoli ms
moist surface for dissolving of gases in alveolar air so they can diffuse across the avleolar walls
adaptation alveoli octw
one cell thick wall reduces diffusion distance
adaptation alve lsa
large surface area for maximum exchange of gases
adap alve rbs
rich blood supply to remove diffused gases and maintain concerntration gradient for future diffusion
why do you need more energy with age
because your metabolism slows down due to things like muscle loss and hormonal changes
