respiratory system

Question 1

what transports oxygen from the atmosphere into the body’s cells and removes carbon dioxide from the body’s cells

Answer 1

respiratory system

Question 2

process of bringing oxygen into the lungs

Answer 2

ventilation; breathing

Question 3

what is the process of air getting into the lungs?

Answer 3

nasal opening-> nasal cavity-> pharynx-> trachea-> right and left bronchus-> bronchioles-> alveoli

Question 4

thin-walled structures that look likecluster of grapes, site of gas exchange, bathed in layer of aqueous surfactant

Answer 4

alveoli

Question 5

terminate at the site of gas exchange

Answer 5

bronchioles

Question 6

this is the throat

Answer 6

pharynx

Question 7

substance that serves as the medium for gas exchange and keeps the lung from collapsing on itself by maintaining surface tension

Answer 7

aqueous surfactant

Question 8

which lung is bigger and why?

Answer 8

right lung because the heart is located to the left

Question 9

which lung has 2 lobes?

Answer 9

the left: superior and inferior

Question 10

since each lobe is divided into bronchopulmonary segment, each segment-

Answer 10

receives air from its own bronchus and receives blood from its own artery

Question 11

pleura

Answer 11

tough, protective double membrane that contains each lobe and is surrounded by pleural fluid

Question 12

where are the lungs located?

Answer 12

thoracic cavity

Question 13

where are the lungs located?

Answer 13

thoracic cavity

Question 14

what organ helps transport oxygen and carbon dioxide throughout the body?

Answer 14

heart

Question 15

what structure changes the volume of the lungs? alveoli or diaphragm?

Answer 15

diaphragm

Question 16

Which condition causes a narrowing of airways in the respiratory system? bronchitis, asthma, or pneumonia?

Answer 16

asthma

Question 17

which explains how the structure of alveoli relates to its f(x)?
A. alveoli are small to increase the transportation of cells
B. alveoli are large to maximize gas exchange
C. the walls of the alveoli are too thin in order to increase rate of diffusion

Answer 17

the walls of the alveoli are too thin in order to increase rate of diffusion

Question 18

which best describes the primary f(x) of respiratory system
A. it exchanges gases between the blood and the air in an environment
B. it maintains proper blood level pH
C. it involves the inhalation and exhalation of gases into the environment

Answer 18

it exchanges gases between the blood and the air in an environment
