Biology Ii Lesson 19

Front 1

Write out the balanced chemical equation for the formation of bicarbonate and a protonfrom CO2 and water (1 pt).

Back 1

H20 + CO2 <-> H2CO3 <-> H+ + HCO3-

Front 2

What ion in the interstitial/tissue fluid changes with changes in CO2.

Back 2

H+

Front 3

Why do osteichtheys have such a high surface area and efficient gas exchange systemcompared to terrestrial animals with lungs?

Back 3

There is less O2 and denser media to move in aquatic environments soosteichtheys need to have a more efficient respiratory system.

Front 4

In regards to gas exchange (external respiration) in gills, how much more efficient iscounter current exchange compared to co-current exchange?

Back 4

It is five times more efficient than co-current exchange.

Front 5

Where does ventilation occur?

Back 5

lungs

Front 6

Where does external respiration occur?

Back 6

between the lungs and blood

Front 7

Where does internal respiration occur?

Back 7

between blood and cells

Front 8

Where does reduction of oxygen to water occur?

Back 8

in the cells

Front 9

Name a gas, other than O2, that can strongly bind to the iron complex in hemoglobin

Back 9

Carbon Monoxide

Front 10

Suppose you were an endurance athlete, how could you increase the oxygen carryingcapacity of your blood?

Back 10

Increase your amount of hemoglobin.

Front 11

Compared to blood with no hemoglobin, about how much do red blood cells containinghemoglobin increase the oxygen binding capacity?

Back 11

100 times.

Front 12

Name an animal that likely has a much higher surface area of olfactory epithelia (witholfactory receptors) than a human?

Back 12

A dog.

Front 13

On a cool dry day, which part of your face is likely the coldest (assuming that you do nothave a head cold)?

Back 13

Your nose.

Front 14

Considering what happens to blood in the kidney, why have hemoglobin in cells (redblood cells) instead of just free in the blood?

Back 14

If hemoglobin was free in the blood it would filter through the kidneys, butbecause it is in the cells it cannot pass through the filter in the kidneys.

Front 15

When your forcibly breathe out...

Back 15

expiratory reserve volume

Front 16

When you forcibly breathe in...

Back 16

Front 17

When you take a normal breath...

Back 17

tidal volume

Front 18

Remaining in the lung after your forcibly breathe out...

Front 19

Where are odors detected?

Back 19

olfactory receptor

Where is air cleaned and moistened?

Back 20

nostrils

Front 21

Where is sound made?

Back 21

vocal cords

Front 22

Where is cartilage in the wall of the tube?

Back 22

trachea

Front 23

Where are ciliated cells found?

Back 23

lungs

Front 24

here is surface area the greatest?

Back 24

nasal cavity

Front 25

Where does exchange of gas between blood and air occur?

Back 25

bronchiole and alveolus

Front 26

Where is elastin important in function?

Back 26

alveoli

Front 27

What drives the movement of gases between air and blood and between blood and tissues?

Back 27

gas concentration differences

Front 28

Sigh got in a knife fight with Godwin over some duck jerky while filming an episode ofCluck Dismally. Godwin stabbed Sigh in the rib cage and ruptured the pleuralmembranes. What is Sigh’s likely clinical outcome?

Back 28

A collapsed lung
