Inhalation
Exhalation

Question 20

Nasal cavity

Answer 20

Filter out dust and pollen from air

Sense of smell

Sound production

Question 21

Pharynx

Answer 21

Throat

Connects oral and nasal cavities to the esophagus and trachea

Question 22

Larynx

Answer 22

Sound production

Prevents food from going into your windpipe

Question 23

Trachea and bronchi

Answer 23

Windpipe

Move air into and out of the lungs

Question 24

Cilia

Answer 24

Keeps some particle out of lungs

Traps them and moves them back up to pharynx

Question 25

Alveoli

Answer 25

Air sacs Take up most of the surface are in the lungs

Question 26

Respiratory system and homeostasis?

Answer 26

High CO2 stimulates more breathing in order to get rid of CO2 Low CO2 stimulates less breaking in order to maintain blood pH (acidity)

Question 27

Major organs of the circulatory system

Answer 27

Heart Blood Blood vessels: arteries, capillaries, veins

Question 28

Arteries

Answer 28

Carry blood from heart to tissues (to capillaries)

Question 29

Capillaries

Answer 29

Where nutrients, chases and wastes are exchanged between blood and tissues

Question 30

Veins

Answer 30

Carry bliss from tissues (from capillaries) back to the heart

Question 31

Blood flow?

Answer 31

Heart>arteries> capillaries> veins> back to the heart

Question 32

SA node

Answer 32

The heart’s natural peacemaker Tells heart to start or stop beating (maintains heartbeat )

Question 33

Villi and microvilli

Answer 33

tiny hair-like projections that increase nutrient absorption. increase the surface area of the small intestine allowing more area for nutrients to be absorbed.
