Total questions: 25
Worksheet time: 13mins
Which of the following is the main muscle for breathing?
Intercostal Muscle
Diaphragm
Sternocleidomastoid
During inhalation, contraction of the diaphragm and the intercostal muscle cause the lung /thoracic cavity to __________ and the air pressure in lungs to _____________.
Contract; Decrease
Expand: Increase
Contract; Increase
Which of the following is the function of alveoli in respiration?
Helping the lungs to stay inflated
Gaseous exchange
Relaxation
Ventilation (breathing) is a regular, rhythmic process which:
moves air into and out of the lungs
protects the airways by clearing them of mucus or irritants
moves gases from an area of high concentration to an area of lower concentration
What is the purpose of the respiratory system?
takes in oxygen and releases nitrogen
takes in carbon dioxide and releases oxygen
takes in oxygen and releases carbon dioxide
takes in nitrogen and releases oxygen
Passage connecting your throat and lungs.
pharynx
bronchial tubes
diaphragm
trachea
Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.
bronchioles
lung lobes
alveoli
capillaries
Muscle that helps your lungs pull in air and push it out.
diaphragm
alveoli
heart
trachea
When you exhale, the diaphragm
moves upwards
moves downwards
flattens
none of the above
This condition occurs when the airway is narrowed due to inflammation of the bronchi.
lung cancer
asthma
emphysema
cystic fibrosis
When the diaphragm relaxes, the pressure in the lungs _______________ and air rushes _________.
increases; in
increases; out
decreases; in
decreases; out
Vital Capacity +Residual Volum=
VITAL capacity
Residual Volume
Total lung Capacity
inspiratory rate
What is labeled at E?
bronchi
trachea
pharynx
none of the above
The volume of air inhaled or exhaled per breath.
Tidal Volume
Diffusion
Breathing Rate
Alveoli
Which blood vessel is involved within Gaseous Exchange?
(a)
Which muscles contract around the ribs during inhalation and exhalation?
(a)
What is the pathway that air follows throughout the body?
Nose-> Trachea -> Bronchi -> Pharynx -> Lungs -> Alveoli
Nose -> Bronchi -> Pharynx -> Trachea -> Lungs -> Alveoli
Nose -> Pharynx -> Trachea -> Alveoli -> Branchi -> Lungs
Nose -> Pharynx -> Trachea -> Bronchi -> Lungs -> Alveoli
When does your lung volume increase?
Inhalation
Exhalation
During exercise, your breathing rate increased in order to accommodate:
Increased carbon dioxide needs of your muscles
Increased oxygen needs of your heart
Increased oxygen needs of your muscles
Increased carbon dioxide needs of your lungs
Which of these are long term effects of exercise on the respiratory system?
Increased vital capacity
Increased lung efficiency
Increased maximum oxygen uptake
All these answers
An increased number of alveoli in the lungs will mean that:
More gaseous exchange will take place
Increased muscle efficiency
More space in the lungs (vital capacity)
More blood can be pumped to the muscles
