Question 1

Which statement is NOT true about the human respiratory system?

Accepted Answer

The glottis is closed by the epiglottis, not the soft palate, during swallowing to prevent food from entering the trachea.

Question 2

In small aquatic animals,such as hydra and planarians,the most common structure used for gas exchange is the

Accepted Answer

Small aquatic animals like hydra and planarians use their body surface for gas exchange due to their simple body structure and the high surface area to volume ratio, which allows efficient diffusion of gases directly through their skin.

Question 3

If an individual wanted to hold their breath underwater for a long period of time they would breath very rapidly prior to the dive.What does this accomplish?

Accepted Answer

A

Question 4

Which organisms use negative pressure to move air into the lungs?

Accepted Answer

All the listed organisms, including ducks, iguanas, humans, and mice, use negative pressure to move air into their lungs. This is a common mechanism in vertebrates where the diaphragm and other muscles create a vacuum to draw air in.

Question 5

The grasshopper is a terrestrial animal that uses its ________ in respiration.

Accepted Answer

Grasshoppers have a tracheal system for respiration, which means they use small tubes called tracheae to transport oxygen throughout their bodies.

Question 6

Ventilation includes

Accepted Answer

Ventilation refers to the process of moving air in and out of the lungs, which includes both inspiration (inhaling) and expiration (exhaling). Illumination is unrelated to ventilation.

Question 7

The earthworm is a terrestrial animal that uses its ________ in respiration.

Accepted Answer

Earthworms respire through their moist body surface, allowing gas exchange directly through their skin.

Question 8

There is unidirectional flow of air for greater absorption of oxygen in

Accepted Answer

Birds have a unique respiratory system with air sacs that allow for a unidirectional flow of air through their lungs, enhancing oxygen absorption.

Question 9

Which of the following increases the surface area available for gas exchange among various organisms?

Accepted Answer

All of these adaptations increase the surface area available for gas exchange, enhancing the efficiency of oxygen and carbon dioxide exchange with the environment.

Question 10

Which features are required for efficient external respiration to take place?

Accepted Answer

Efficient external respiration requires a moist, thin gas exchange region with a large surface area to facilitate the diffusion of gases.

Question 11

The exchange of gases between the lungs and the blood occurs by

Accepted Answer

Gas exchange in the lungs occurs by diffusion, where oxygen and carbon dioxide move across the alveolar and capillary membranes from areas of higher concentration to areas of lower concentration.

Question 12

Gas exchange takes place by the physical process of diffusion.Use the diagram to describe where diffusion is occurring and what gases are diffusing.  Identify and describe what type of respiration involves the lungs (A)and what type involves the tissue fluids (B).
A: ________ Respiration
B: ________ Respiration
Describe what is occurring,in terms of gaseous exchange,at C,D,E and F.
C: ________
D: ________
E: ________
F: ________

Question 13

Gills are used in respiration by all of the following aquatic animals EXCEPT

Accepted Answer

Polychaete worms use parapodia, which are paired appendages, for respiration rather than gills.

Question 14

In order to maximize diffusion across the surfaces of a gill,oxygen-rich water flows in the opposite direction of oxygen-poor blood.This concept is called

Accepted Answer

Countercurrent flow is a mechanism that maximizes the diffusion of gases by having water and blood flow in opposite directions, maintaining a gradient that facilitates efficient oxygen transfer.

Question 15

Trace the path of an inhaled air molecule in a human being.

Question 17

Opercula are

Accepted Answer

Opercula are bony or cartilaginous structures that cover and protect the gills in fish.

Question 18

How do insects overcome the inefficiency of their hemolymph flow in taking oxygen to their tissues?

Accepted Answer

Insects have a tracheal system, which consists of a network of tiny tubes (tracheae) that deliver oxygen directly to their cells, bypassing the need for hemolymph to transport oxygen.

Question 19

Which of the following events involves the exchange of gases across a cell membrane?

Accepted Answer

External respiration involves the exchange of gases between the alveoli and the blood, while internal respiration involves the exchange of gases between the blood and body tissues. Both processes involve gas exchange across cell membranes.

Question 20

Which of these organisms is able to use several body surfaces,such as gills,skin,and lungs,for respiration?

Accepted Answer

Amphibians can use multiple body surfaces for respiration, including their skin, gills (in larval stages), and lungs.
