What is the route of oxygen?
Nose/Mouth
Larynx
Trachea
Bronchi
Bronchioles
Alveoli
Capillaries
Transport in Blood
What makes the respiratory system?
Nose
Mouth
Throat
Voice Box
Windpipe
Lungs
Blood Vessels
Purpose of the respiratory system
Get oxygen into the body
Remove Carbon Dioxide from the body
What is inhaled air made up of?
20% Oxygen
0.4% Carbon Dioxide
What is exhaled air made up of?
16% Oxygen
4% Carbon Dioxide
What happens to our breathing when we begin to exercise?
Increased breathing rate
Deeper heavier breathes
Gaseous Exchange
The alveoli are surrounded by capillaries (very narrow tubes) that carry blood.
Haemoglobin inside red blood cells binds to oxygen, which diffuses into the blood so it can be transported around the body to be deposited into the living cells.
A series of chemical reactions take place, which combines glucose (from food) with oxygen to release energy, along with carbon dioxide and water.
While oxygen is taken in carbon dioxide is given out or exchanged, into the alveoli and is then breathed out.
What happens to the digraphm when we breath?
When inhaling, the digraphm contracts and flattens. Increasing chest volume and drawing air in. When exhaling out, it relaxes and returns to a dome shape, decreasing chest volume and pushing out.
What is Oxygen Debt?
The amount of oxygen needed at the end of physical activity to break down lactic acid,
What is the long term effects of our respiratory system?
It will improve your VO^2 max
Why does the cardiovascular and respiratory system work together?
An efficient respiratory system aids the cardiovascular system by providing a constant supply of oxygen for the muscles by removing Carbon Dioxide.
During exercise, the body needs to take a sufficient amount of oxygen and eliminate the carbon dioxide produced by the muscles while they are working.
Exam question:
John is an elite 400m runner. Explain why having an efficient cardiorespiratory system is important for his sport.
(3 marks)
The cardiorespiratory system delivers oxygen to the muscles and removes carbon dioxide during exercise. John needs to get more oxygen in the blood to the working muscles quickly such as the gastrocnemius, hamstrings and gluteals. This is vital for John’s performance as if he doesnt supply enough oxygen to the working muscles, he will fatigue faster and not finish the race faster.
Respiration
The movement of air from outside the body into the cells within tissues.
Diagraphm
The primary muscles used in the process of inspiration or inhalation. A dome-shaped sheet of muscle that seperates the chest from the rest of the body cavity.
Trachea
The tube that takes air into the chest
