- Q1
What organ systems work together to allow the exchange of gases and distribute nutrients although out the body?
Respiratory and digestive system
Respiratory and circulatory system
Circulatory and excretory system
Circulatory and digestive system
60sS9LT-la-b-26 - Q2
It is a part of the respiratory system where gas exchange occurs.
alveoli
bronchioles
bronchi
lungs
60sS9LT-la-b-26 - Q3
The following are functions of the respiratory system EXCEPT:
facilitate the absorption of oxygen
carry blood to all parts of the body
responsible for gas exchange
bring carbon dioxide out of the body through exhalation
60sS9LT-la-b-26 - Q4
What happens in the diaphragm when we exhale (breath out)?
The diaphragm relaxes and moves downwards.
The diaphragm relaxes and moves upwards.
The diaphragm contracts and moves upwards.
The diaphragm contracts and moves downwards.
60sS9LT-la-b-26 - Q5
What will happen if the epiglottis does not close the entrance of the airways?
The food particles will block the opening of the trachea and a person will have difficulty breathing.
The larynx will be blocked with food particles.
The pharynx will have difficulty swallowing.
The food particles will block the bronchioles thus making it difficult to breathe in and breathe out.
60sS9LT-la-b-26 - Q6
Which is NOT a function of the circulatory system?
Transport other materials through the body.
Remove carbon dioxide and wastes from cells.
Deliver oxygen and nutrients to cells.
Break down carbohydrates into glucose.
60sS9LT-la-b-26 - Q7
Which blood vessel carries blood away from the heart?
Vein
Blood vessel
Capillary
Artery
60sS9LT-la-b-26 - Q8
If a rupture occurs in the pulmonary artery, which passageway is affected?
The passageway of blood going to the aorta.
The passageway of blood going to the vena cava.
The passageway of blood going to the right atrium.
The passageway of blood going to the lungs.
60sS9LT-la-b-26 - Q9
Which path in the figure does the blood follow through
the heart as it returns from the head and body?
1→2
4→3
2→1
3→4
60sS9LT-la-b-26 - Q10
In which chamber does the blood flow while transporting fresh oxygen?
2
1
4
3
60sS9LT-la-b-26 - Q11
For the body to maintain homeostasis, the intake of oxygen into the lungs must be followed by which process?
A decrease in gas exchange.
A decrease in blood flow.
An increase in blood pressure.
The exhalation of carbon dioxide.
60sS9LT-la-b-26 - Q12
How do the respiratory and circulatory systems work together?
They break down food into energy and eliminate waste.
They are responsible for the movement of the body.
They send chemical signals throughout the body via hormones.
They supply the body's cells with oxygen.
60sS9LT-la-b-26 - Q13
When the body needs more oxygen, how does the circulatory system respond?
The heart beats faster to match the increase in breathing rate.
Blood moves more slowly through the organs to carry away more waste.
More blood is sent to the lungs and less to the rest of the body.
The blood vessels in the arms and legs constrict to conserve oxygen.
60sS9LT-la-b-26 - Q14
Smoking is the common cause of emphysema. What happens when you have emphysema?
The amount of oxygen in your bloodstream ultimately decreases.
The blood pressure in your pulmonary artery decreases
The blood in your lungs becomes oxygenated
The amount of oxygen in your blood increases
60sS9LT-lc-27 - Q15
What occurs when a blood clot blocks the blood supply from the heart?
Anemia
Heart failure
