Question 1

What Is the most important body process?

Answer 1

Breathing is the most important body process

Question 2

What is the purpose of breathing?

Answer 2

The purpose of breathing is to inhale oxygen and exhale carbon dioxide

Question 3

What is the name of the breathing body process?

Answer 3

The respiratory system is the breathing process

Question 4

What would happen without the exchange of gasses?

Answer 4

Without the exchange of gasses you would die

Question 5

What is the role of the lungs?

Answer 5

The lungs deliver oxygen for cellular respiration and excrete carbon dioxide

Question 6

What is breathing?

Answer 6

Breathing is bringing in oxygen and letting carbon dioxide out

Question 7

When does breathing begin?

Answer 7

Breathing begins when you breath in through your nose or mouth

Question 8

Where is the air warmed and filtered?

Answer 8

Air is warmed and filtered by tiny hairs called cilia and sticky mucus in your nose

Question 9

What do the cilia do?

Answer 9

Cilia trap dirt and particles and either push them back though the nose (boogers) or digest them

Question 10

Where does the air travel after your nose?

Answer 10

Air travels down the pharynx, past the epiglottis and through your larynx

Question 11

What is the larynx?

Answer 11

Larynx is your voice box

Question 12

What produces sound in the larynx?

Answer 12

The larynx has cords which vibrate as air passes through them, which makes sound.

Question 13

Where does air go after the larynx?

Answer 13

After the larynx the air goes down your trachea

Question 14

Where can you feel your trachea?

Answer 14

Your trachea is the bumps you feel on the front of your neck

Question 15

What makes the bumps in your trachea?

Answer 15

the trachea bumps are cartilage which is flexible but helps to maintain the shape, like a vacuum hose.

Question 16

At the base of the trachea, what are the two tubes called?

Answer 16

The trachea splits into the two bronchi (singular I bronchus)

Question 17

Where does air go after the bronchi?

Answer 17

After the bronchi, air goes into your lungs

Question 18

What do bronchi branch into?

Answer 18

Bronchi branch into bronchioles

Question 19

What are the tiny thin walled sacs called

Answer 19

Bronchioles branch into tiny sacs called alveoli

Question 20

How many alveoli are there?

Answer 20

there are millions of alveoli

Question 21

What happens in the alveoli?

Answer 21

Gas exchange happens in the alveoli

Question 22

What surrounds each alveolus?

Answer 22

Thousands of capillaries surround each alveolus

Question 23

What do alveoli look like?

Answer 23

Alveoli look like bunches of grapes

Question 24

Where do the respiratory and the circulatory systems interact?

Answer 24

In the alveoli, the respiratory and the circulatory systems interact

Question 25

What comes from the capillaries surrounding the alveoli?

Answer 25

De-oxygenated blood comes from the capillaries around the alveoli

Question 26

Which way does diffusion work in the alveoli?

Answer 26

Oxygen diffuses into the blood, and carbon dioxide diffuses out of the blood in the alveoli walls.

Question 27

What happens to the blood once it is full of oxygen from the lungs?

Answer 27

From the lungs, blood is pumped back up into the heart and then to the body

Question 28

What is this whole process called?

Answer 28

The process of getting oxygen and getting rid of carbon dioxide is called gas exchange

Question 29

What are two diseases that occur from smoking.

Answer 29

Cancer and emphysema are caused by smoking tobacco

Question 30

What is emphysema?

Answer 30

Emphysema is when the alveoli lose their elasticity which makes breathing very difficult

Question 31

What other problem usually happens at the same time as emphysema? This is call co-morbidity

Answer 31

Heart disease usually occurs at the same time as emphysema

Question 32

What does carcinogenic mean?

Answer 32

Carcinogenic means it causes cancer

Question 33

How many carcinogenic (cancer causing) chemicals are in cigarettes?

Answer 33

At least 50 carcinogens are in cigarettes

Question 34

What are the six most harmful chemicals in cigarettes?

Answer 34

Nicotine, are, carbon monoxide, formaldehyde, hyrogen cyanide and benzine are the most harmful chemicals in cigarettes

Question 35

What else do cigarettes destroy in your body?

Answer 35

Cigarettes also destroy the cilia which lines the respiratory system, so that dirt from the air cannot be removed easily.

Question 36

What is the order of the path air takes

Answer 36

mouth/nose — nasal cavity – pharynx — larynx— trachea — bronchus—bronchioles – lungs – alveoli

Question 37

What is the difference between the bronchus and the bronchioles?

Answer 37

Bronchioles are smaller versions of the bronchus

Question 38

What is the gas exchange called?

Answer 38

Diffusion is the process of gas exchange

Question 39

How are alveoli structured to speed up gas exchange?

Answer 39

Alveoli are very thin, there are millions of them, and they are surrounded by capillaries which speeds up air exchange

Question 40

What happens to oxygenated blood?

Answer 40

From the capillaries it goes back pulmonary vein and into the heart and then pumped to the rest of the body
