What adaptations make the alveoli good at their job?
they are round, so can fit easily in the lungs
they have a large surface area, so can transport many oxygen molecules
they have a good blood supply
they have thick walls so are strong cells
which happens during inhalation?
rib muscles expand/ rib cage expands / diaphragm moves down
rib muscles contract / rib cage contracts/ diaphragm moves down
rib muscles contract / rib cage expands / diaphragm moves down
rib muscles contract / rib cage contracts / diaphragm moves up
What do the alveoli most resemble?
bananas
grapes
pineapples
avocados
which happens during exhalation?
rib muscles expand/ rib cage contracts/ diaphragm moves up
rib muscles contract / rib cage contracts/ diaphragm moves down
rib muscles expand / rib cage expands / diaphragm moves down

Why is respiration extremely important?
To help us perform voluntary activities
To sustain life and provide necessary oxygen to cells
To remind ourselves to inhale and exhale
To break down food molecules for energy
Which of the following is true about breathing and respiration?
Breathing involves the breakdown of food molecules, while respiration is the exchange of gases.
Breathing and respiration are the same thing.
Breathing is a part of respiration, but they have different functions.
Breathing is the process of deriving energy from food molecules.
What is cellular respiration?
The exchange of gases at the nasal level
The exchange of gases between the lungs and blood
The breakdown of food molecules by the cells
The exchange of gases within the cells
How is internal respiration different from cellular respiration?
Internal respiration occurs at the nasal level, while cellular respiration occurs within the cells.
Internal respiration involves the breakdown of food molecules, while cellular respiration is the exchange of gases.
Internal respiration is the exchange of gases between the lungs and blood, while cellular respiration is the breakdown of food molecules.
Internal respiration is restricted to the cells, while cellular respiration occurs in the lungs.
Do all organisms have a similar respiration system?
Yes, all organisms have the same respiration system.
No, the mechanisms of respiration vary from habitat to habitat and from organism to organism.
Yes, but the mechanisms of respiration are different in different organisms.
No, only humans have a respiration system.
Breathing is ...
Breaking down food
Making noise
Inhaling and Exhaling Air
Producing energy from food
Which organ excretes carbon dioxide?
Lungs
Liver
Heart
Kidney
What happens to your breathing rate when you exercise?
It increases
It decreases
It stays the same
What is the primary function of the diaphragm in the process of breathing?
To pump blood throughout the body
To filter air entering the lungs
To contract and create a vacuum for air intake
To exchange oxygen and carbon dioxide in the blood
Which of the following best describes the difference between respiration and breathing?
Respiration is the physical act of inhaling and exhaling, while breathing is the chemical process of energy production.
Breathing is the physical act of inhaling and exhaling, while respiration is the chemical process of energy production.
Both respiration and breathing refer to the chemical process of energy production.
Both respiration and breathing refer to the physical act of inhaling and exhaling.
