Respiratory system

Question 1

what are we extracting from the air when we breathe

Answer 1

oxygen

Question 2

what is it called when oxygen and nutrients react to create energy

Answer 2

cellular respiration

Question 3

what is the equation of cellular respiration

Answer 3

glucose + oxygen = cardon dioxide + Energy +water

Question 4

what are the two parts of the respiratory system

Answer 4

the respiratory tract

the lungs

Question 5

what is the order of the respiratory tract

Answer 5

• the nasal passages
• the pharynx
• the larynx
• the trachea
• the bronchi (bronchioles)

Question 6

how does the air get from the respiratory tract to the lungs

Answer 6

air exits the respiratory tract through the bronchioles and then goes into the lungs

Question 7

what are the nasal passages

Answer 7

• they are the nostrils

- filters and warms

Question 8

what are the pharynx

Answer 8

• passage way to the bronchi

- carries air to the lungs and food to the esophogus

Question 9

what is the epiglottis

Answer 9

• flap of skin
• blocks the trachea
• so food it dosen’t go into respiratory tract

Question 10

larynx

Answer 10

• upper section of the trachea
• vocal cords
• carries air

Question 11

trachea

Answer 11

• made up of cartilage rings

- filters, warms the air

Question 12

bronchi

Answer 12

• tubes branching of the trachea

- brings air to lungs

Question 13

lungs

Answer 13

• organs

- ensures gas exchange

Question 14

what happens when the volume increases in the lungs

Answer 14

decrease pressure

Question 15

what happens when the volume decreases in the lungs

Answer 15

increase pressure

Question 16

where does the air go when the pressure is high outside

Answer 16

it goes into the lungs

Question 17

where the does the air go when the pressure is high in the lungs

Answer 17

air exits the lungs

Question 18

what are the two states of respiration

Answer 18

• inhalation

- exhalation

Question 19

what are the parts of the body that are responsible for inhalation and exhalation

Answer 19

lungs, ribs, diaphragm

Question 20

what happens when someone inhales

Answer 20

• muscles and diaphragm contract
• rib cage rises
• diaphragm moves down
• lung volume increases, pressure decreases
• oxygen rushes into the lungs

Question 21

what happens when someone exhales

Answer 21

• muscles and diaphragm relax
• rib cage descends
• diaphragm rises
• lung volume decreases, pressure increase
• carbon rushes out of the lungs

Question 22

what is the process of cellular respiration

Answer 22

1. air goes to our lungs

2. oxygen goes into our cells then carbon dioxide is created

Question 23

where does gas exchange happen

Answer 23

in the alveoli

Question 24

what are the alveoli

Answer 24

make up the lungs, made up of capillaries, responsible for gas exchange

Question 25

what is diffusion

Answer 25

when substance goes into a region with low concentration from a high concentration area

Question 26

what would happen to a person if their alveoli swelled up

Answer 26

if the alveoli would be swollen oxygen and CO2 would have trouble getting in and out
