Question 11

During a soccer match, Emily notices her breathing rate increases significantly after sprinting. Which of the following best explains why this happens?

Answer 11

Her body needs to expel excess carbon dioxide and take in more oxygen

Question 12

Michael, who has asthma, begins to experience difficulty breathing after being exposed to dust. What is the most likely physiological reason for this reaction?

Answer 12

His bronchioles have constricted, reducing airflow to the lungs

Question 13

While scuba diving, Lisa ascends too quickly from deep underwater. She suddenly feels severe chest pain and dizziness. What is the most likely reason for her symptoms?

Answer 13

The rapid pressure change caused her lungs to over-expand and possibly rupture

Question 14

Which of the following is a function of the respiratory system
A) gas exchange
B) absorption of nutrients
C) structural support
D) transport for oxygen

Answer 14

A) gas exchange

Question 15

When the diaphragm contracts, what occurs

Answer 15

Inhalation

Question 16

On a cold winter night, Mark feels that breathing is slightly more difficult when he jogs outside. What could be the reason for this sensation?

Answer 16

Cold air causes the bronchioles to constrict, reducing airflow

Question 17

A car accident causes a deep chest injury in David, puncturing one of his lungs. He struggles to breathe and his oxygen levels drop. Why does this injury affect his breathing?

Answer 17

The hole allows air to enter the chest cavity, preventing lung expansion

Question 18

The name of the tiny air sacs in the lungs where gas exchange takes place

Answer 18

Alveoli

Question 19

Which one of the following is not a function of the nose
A) to warm air entering the nose
B) to trap bacteria
C) to trap dust particles
D) to exchange gases

Answer 19

D) to exchange gases

Question 20

The exchange of gases between blood and cells is called

Answer 20

Internal respiration

Question 21

The nose serves all the following functions EXCEPT:
A) as the initiator of the cough reflex
B) warming and humidifying the air
C) cleansing the air
D) as a passageway for air movement

Answer 21

A) as the initiator of the cough reflex

Question 22

The digestive and respiratory passageways meet one another at a region of the pharynx referred to as what

Answer 22

Oropharynx

Question 23

The cartilage of the larynx that resembles a ring and connects the trachea and larynx

Answer 23

Cricoid cartilage

Question 39

What are the 8 steps of respiration?

Answer 39

1. Air containing oxygen is inhaled into the alveoli during the inspiratory phase of pulmonary ventilation 2. Oxygen diffuses from alveoli into the blood of pulmonary capillaries during alveolar gas exchange 3. Oxygen is transported within the blood from the lungs to the systemic cells of the body 4. Oxygen diffuses from the blood within the systemic capillaries into the systemic cells during systemic gas exchange 5. Carbon dioxide diffuses from systemic cells into the blood within systemic capillaries during systemic gas exchange 6. Carbon dioxide is transported within the blood from systemic cells to the lungs 7. Carbon dioxide diffuses from the blood within the pulmonary capillaries into the alveoli during alveolar gas exchange 8. Air containing carbon dioxide is then exhaled from the alveoli into the atmosphere during the expiratory phase of pulmonary ventilation

Question 40

Explain the difference between pulmonary ventilation and alveolar ventilation

Answer 40

Pulmonary ventilation, known as breathing, is the movement of air between the atmosphere and the alveoli. It consists of two cyclic phases: inspiration (inhalation) which brings air into the lungs, and expiration (exhalation) which forces air out of the lungs. Alveolar ventilation is defined as the volume of fresh air entering and alveolar air leaving the alveoli per minute.

Question 41

James is eating a sandwich while laughing. Suddenly, he starts coughing uncontrollably. What likely happened in James' respiratory system, and which structure is responsible for preventing food from entering the airway?

Answer 41

James was laughing while eating which caused food to accidentally enter the airway instead of going down the esophagus. This resulted in him coughing to clear the obstruction. The epiglottis is responsible for covering the trachea when swallowing. If the epiglottis fails to close properly, food can enter the airway, leading to choking and coughing.
