24
Respiration when the body is at rest
Aerobic
25
As you excersise you breathe harder and harder and deeper and the heart beats ....... To get ........... To the muscles
Faster | Oxygen
26
When excersising very hard, the ......... Cannot get enough oxygen to the muscles
Heart
27
What is anaerobic respiration
When excersising very hard, the heart cannot get enough oxygen the muscles
28
What is the equation for anaerobic respiration in muscle
Glucose -> lactic acid + energy
29
Which type of respiration releases more energy
Aerobic
30
Equation for anaerobic respiration in yeast
Glucose -> ethanol + carbon dioxide + energy
31
Why is lactic acid harmful
It's toxic
32
What effect does lactic acid have on the body
It builds up in your body
33
What respires
All living things
34
How is oxygen used in respiration
It is used up
35
What is glucose in respiration
Used up
36
What is carbon dioxide in respiration
Produced
37
What is water in respiration
Produced
38
What is the purpose of respiration
To produce energy
39
What is respiration
A chemical reaction in all cells
40
Is breathing and respiration the same
No
41
Equation for respiration
Oxygen + glucose -> carbon dioxide + water + energy
42
respiration
``` Need oxygen Need fuel Produce carbon dioxide and water as waste Energy released Take place in cells ```
43
Network of capillaries
Gases can easily pass through blood
44
What is present in breathing out
Greater quantity Water vapour Carbon dioxide
45
Present in breathing in
Oxygen | Smaller quantity
46
Exhaled air has a ......... temperature then air we breathe in because ........ .in the form of ........... is ............ in respiration
Higher Energy Heat Released
47
Oxygen enters the blood in the .......
Body cells
48
Carbon dioxide enters the blood in
Body cells
49
Oxygen leaves the blood in the
Body cells
50
Carbon dioxide leaves the blood in the
Lungs
51
We breathe faster why?
Because respiration is happening at a faster rate and more heat is given off
52
During intensenphysical activity what happens?
The blood cannot supply enough oxygen for the cells' needs so you get anaerobic respiration
53
Our heart beats faster
In order to take in oxygen more quickly
54
We feel hotter.
In order to take oxygen to the cells more quickly
55
What is the same about plant and animal respiration
``` Oxygen is used up Breathe with lungs Give out water vapour Give out heat as respire Blood to carry oxygen ```
56
Step 1-4
- The diaphragm muscle contracts and moves down - The rib muscles contract and the rib cage expands (moves up and out) - the chest is bigger so the air pressure in the lungs will be reduced - air enters the lungs
57
Steps 1-4 exhaling
- The diaphragm relaxes and moves up - the rib cage muscles relax and the rib cage gets smaller (down and in) - the chest is smaller so the air pressure in the lungs will be higher - air leaves the lungs
58
Bell jar exhaling
- the rubber sheet is pushed up - this decreases the volume inside the bell jar - the pressure inside the bell jar increases - air moves from high pressure to low pressure - so air leaves the balloon
59
When exercising why do we breath faster
In order to take in oxygen more quickly
60
In excersise why do our hearts beat faster
In order to take oxygen to the cells more quickly
61
Why in excersise do we feel hotter
Because respiration is happening at a faster rate and more heat is given off
