Respiratory system Flashcards
(6 cards)
How does carbon monoxide impact the respiratory system
Carbon monoxide has a higher affinity to haemoglobin monoxygen
This results in more carboxyhaemoglobin and less oxyhaemoglobin
This means less oxygen is transported around the body and to the muscles
It also binds for a long time meaning less haemoglobin is available to bind to oxygen
It can cause headaches, dizziness and shortness of breath resulting in faster fatigue
How does damaged alveoli impact the respiratory system
Damaged alveoli means means its harder for gases to diffuse
Slower diffusion- less surface area for gaseous exchange
Less oxygen and CO2 diffusion due to reduced surface area and less alveoli to perform diffusion
Causes coughing, wheezing, shortness of breath
How does damaged cilia impact the respiratory system
Damaged cilia can cause a build up of mucus in the airways and cause blockages or narrow airways
This makes it harder to breathe and it restricts oxygen intake
This increases fatigue and breathing rate
It decreases endurance and oxygen uptake
How does nicotine impact respiration
Nicotine restricts the bronchioles as they are small passages in the lungs that lead to alveoli
This reduces oxygen intake and airflow
It also stimulates the autonomic nervous system which stimulates adrenaline
This increases heart rate and fatigue
It decreases air flow, oxygen uptake and performance
What is and how does bronchitis impact respiration
Bronchitis is an inflammation of the airways caused by irritation of the trachea and bronchi
They swell up and fill with mucus
Results in fatigue, shortness of breath chest tightness, increased breathing rate, reduced stamina, coughing and wheezing
