What is respiration?
The release of energy from food chemicals
1 of 19
What is inspiration?
Breathing in
2 of 19
What is expiration?
Breathing out
3 of 19
How does the air we breathe end up in the alveoli?
1. Air passes through the nose or mouth and goes down the trachea (windpipe) 2.The trachea splits into two tubes called bronchi, one leading to each lung 3.The bronchi split into smaller tubes called bronchioles 4.The bronchioles end at the alveoli
4 of 19
What takes place at the alveoli?
Gas exchange
5 of 19
What is the area inside the chest containing the lungs and heart called?
The chest cavity
6 of 19
The body collects carbon dioxide as it travels around the body, where is it taken?
To the lungs where is moves from the blood to the alveoli
7 of 19
What type of blood cells does the oxygen from the alveoli move to?
Red blood cells
8 of 19
What is vital capacity?
The maximum volume of air you can breathe out after breathing in as much as you can
9 of 19
Wjat is residual volume?
The amount of air left in your lungs after you have breathed out as hard as you can
10 of 19
What is tidal volume?
The amount you breathe in and out in one normal breath
11 of 19
What is oxygen debt?
The amount of oxygen needed after exercise to return to its normal state
12 of 19
Regular exercise increases your lung capacity therefore you can get more oxygen into your lungs and blood stream per breath, how does this effect your ability to exercise?
You have a better oxygen supply to the body so you should be able to exercise for longer
13 of 19
Cigarette smoke contains tar which clogs up the alveoli and makes it harder for gas exchanges to take place, what eventually happens to the alveoli if you smoke continously?
They collapse and stop working
14 of 19
Cigarette smoke contains the addictive drug and poison nicotine. What effect does nicotine have on blood vessels in the lungs?
Nicotine causes the blood vessels to tighten which slows the blood flow into the lungs making the gas exchange in the alveoli less efficient
15 of 19
During inspiration what happens to the intercostal muscles?
They contract
16 of 19
During expiration what happens to the diaphragm?
Relaxes
17 of 19
What is the equation for aerobic respiration?
Glucose + Oxygen -----> Energy + Carbon Dioxide + Water
18 of 19
What is the equation for anaerobic respiration?
Glucose -----> Energy + Lactic Acid
