Animal Form/Function - Respiratory system

Question 1

Animals require this for aerobic functions

Answer 1

O2

Question 2

What happens if cells are not directly exposed to the outside environment?

Answer 2

then some
mechanism must provide gas exchange to internal cells, delivering O2 and removing waste CO2

Question 3

The movement of gas in and out of the atmposphere

Answer 3

Respiration

Question 4

This is also used to describe cellular respiration

Answer 4

Respiration

Question 5

the process of producing ATP within the mitochondria of cells

Answer 5

Cellular respiration

Question 6

Gas exchange mechanism found in animals

Answer 6

Direct with environment, Gills, Tracheae, Lungs

Question 7

Are evaginated structures, or outgrowths from the body, that create a large surface area over which gas
exchange occurs.

Answer 7

Gills

Question 8

Gill cover

Answer 8

Opuculum

Question 9

Chitin-lined tubes

Answer 9

Tracheae

Question 10

Oxygen enters (or CO2 exits)
the tracheae through openings called

Answer 10

Spiracles

Question 11

Are invaginated structures, or cavities within the body of the animal

Answer 11

Lungs

Question 12

Occurring in many spiders, are stacks of flattened membranes enclosed in an internal chamber

Answer 12

Book lungs

Question 13

Gas exchange in humans process

Answer 13

Nose, pharynx, larynx, Trachea, Bronchi, Bronchioles, Alveolus, Diffusion between alveolar chambers and blood, Bulk flow of O2, Diffusion between blood and cells, Bulk flow of CO2, Bulk flow of air in and out of the lungs, Control of respiration

Question 14

Contains the voice cords

Answer 14

Larynx

Question 15

covers the trachea, preventing the entrance of solid and liquid material.

Answer 15

Epiglottis

Question 16

trachea branches into two

Answer 16

Bronchi (Sing. Bronchus)

Question 16

Narrower tubes of Bronchi

Answer 16

Bronchioles

Question 16

Each bronchiole branch ends in a small sac called

Answer 16

Aveolus

Question 17

Formation of carbonic acid is catalyzed by this enzyme

Answer 17

Carbon Anhydrase

Question 18

The volume of the lungs is increased by

Answer 18

Contraction of the diaphragm and intercostal muscles

Question 19

What are the mechanics of respiration?

Answer 19

Lung volume increases while air pressure decrease, air rushes to the lungs by bulk flow, when the diaphragm and intercostal muscles relax, the volume of the lungs decreases, raising the pressure on the air, causing the air to rush out

Question 20

This is an example of how homeostasis is maintained by negative feedback

Answer 20

Regulation of respiratory rate
