Respiratory System

Question 1

Primary functions

Answer 1

To provide oxygen to body tissues for cellular respiration
Remove the waste product carbon dioxide
Help to maintain acid-base balance

Question 2

Second functions

Answer 2

Secondary functions are voice production, body temperature regulation, acid-base regulation, & the sense of smell

Question 3

Conducting zone

Answer 3

Moves air in and out of the lungs

Question 4

Respiratory zone

Answer 4

Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli

Question 5

Nose

Answer 5

The major entrance and exit for the respiratory system

Question 6

Pharynx

Answer 6

Is the part of the throat situated immediately posterior to the mouth and nasal cavity, and superior to the esophagus and larynx

Question 7

Larynx

Answer 7

Regulates volume of air

Question 8

Trachea

Answer 8

The trachea is the long tube that connects your larynx (voice box) to your bronchi

Question 9

Alveolar duct

Answer 9

Alveolar ducts are tiny ducts that connect the respiratory bronchioles to alveolar sacs, each of which contains a collection of alveoli

Question 10

Alveolus

Answer 10

Any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange

Question 11

Alveolar sac

Answer 11

Tiny air sacs at the end of the bronchioles (tiny branches of air tubes in the lungs). The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out

Question 12

Boyle’s Law (formula)

Answer 12

p1v1=p2v2

Question 13

Boyle’s Law (explanation)

Answer 13

States that at a fixed temperature, the volume of gas is inversely proportional to the pressure exerted by the gas

Question 14

Inspiration

Answer 14

When the lungs inhale, the diaphragm contracts and pulls downward. As a result, air rushes in and fills the lungs

Question 15

Expiration

Answer 15

When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases

Question 16

Medulla Oblongata

Answer 16

The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration

Question 17

Eupnea

Answer 17

Normal respiration

Question 18

Diaphragmatic breathing

Answer 18

Involves fully engaging the stomach, abdominal muscles, and diaphragm when breathing. This means actively pulling the diaphragm down with each inward breath

Question 19

Hyperpnea

Answer 19

Abnormally rapid or deep breathing happens when your body needs more oxygen. Exercise or physical activity is the most frequent situation for hyperpnea

Question 20

Diaphragm

Answer 20

The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily

Question 21

Atelectasis

Answer 21

Complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid

Question 22

Pneumonia

Answer 22

Pneumonia is an infection that inflames your lungs’ air sacs (alveoli). The air sacs may fill up with fluid or pus

Question 23

Asthma

Answer 23

Asthma is a chronic lung disorder that causes airways to become inflamed. The muscles surrounding the airways also tend to tighten, which makes the already clogged airways even narrower

Question 24

Emphysema

Answer 24

Condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness

Question 25

Chronic Bronchitis

Answer 25

Chronic bronchitis is long-term inflammation of the bronchi. It is common among smokers

Question 26

Pneumothorax

Answer 26

Pneumothorax is air around or outside the lung. It may result from chest trauma, excess pressure on the lungs or a lung disease

Question 27

Tuberculosis

Answer 27

Tuberculosis (TB) is a potentially serious infectious disease that mainly affects the lungs. The bacteria that cause tuberculosis are spread from person to person through tiny droplets released into the air via coughs and sneezes
