Breathing/Respiration Flashcards
Steps of EXHALATION…
1️⃣Intercostal muscles relax 2️⃣Moves ribs down and in 3️⃣Diaphragm relaxes 4️⃣Diaphragm moves up 5️⃣Decreases volume inside the lungs 6️⃣Increases the pressure 7️⃣Air moves out
Steps of INHALATION…
1️⃣Intercostal muscles contract 2️⃣Moves ribs up and out 3️⃣Diaphragm contracts 4️⃣Diaphragm moves down 5️⃣Increase volume inside the lungs 6️⃣Decreases the pressure 7️⃣Air moves in
1 difference between anaerobic and aerobic respiration?
Aerobic respiration uses oxygen and anaerobic doesn’t
What are the differences between inhaled and exhaled air?
Oxygen levels decreased for your exhaled air, because it has been absorbed into the blood. Carbon dioxide levels increased for your exhaled breaths, your cells making CO2 by respiration.
How are lungs adapted for gas exchange?
⭐️Short diffusion distance
⭐️Large surface area
⭐️Large blood supply
⭐️Ventilation
What is the word equation for anaerobic respiration in plants?
Glucose ➡️ ethanol + carbon dioxide
What is the word equation for aerobic respiration?
Glucose + oxygen ➡️ carbon dioxide + water
Heart rate increases during exercise explain how…
You are doing more respiration
How much oxygen is there in the air?
21%
How much nitrogen is in the air?
79%
How much oxygen is inhaled?
21%
How much oxygen is exhaled?
17%
How much carbon dioxide is inhaled?
A very small amount
How much carbon dioxide is exhaled?
3%
How much nitrogen is inhaled?
79%
How much nitrogen is exhaled?
79%
How much water vapour is inhaled?
A small amount
How much water vapour in exhaled?
A large amount
Oxygen levels have decreased for exhaled air, why is this?
This is because the oxygen has been absorbed into blood for respiration in cells.
Carbon dioxide levels have increase for inhaled air, why is this?
This is because CO2 has been made in the cells by doing respiration.
What happens to the nitrogen levels?
They stay the same
Why do we need energy?
⭐️Movement
⭐️Active transport
⭐️Making larger molecules
➡️Making proteins from amino acids
What is respiration?
Respiration is the process by which food molecules are broken down to release energy.
Energy is released in the form of…
ATP
