Total questions: 26
Worksheet time: 18mins
Which organ is primarily responsible for pumping blood throughout the body?
Lungs
Heart
Liver
Kidney
What is the main function of the alveoli in the pulmonary system?
Pumping blood
Gas exchange
Filtering waste
Producing hormones
Which blood vessels carry oxygenated blood away from the heart?
Veins
Arteries
Capillaries
Venules
What is the primary function of red blood cells?
Fight infection
Carry oxygen
Clot blood
Produce hormones
Which structure prevents food from entering the trachea during swallowing?
Diaphragm
Epiglottis
Larynx
Bronchi
Which chamber of the heart receives oxygen-poor blood from the body?
Left atrium
Right atrium
Left ventricle
Right ventricle
Which of the following best describes the function of the diaphragm in breathing?
It filters air
It contracts and relaxes to change lung volume
It produces mucus
It pumps blood
How does the structure of capillaries support their function in the cardiovascular system?
Their thick walls allow for high pressure
Their thin walls allow for easy exchange of gases and nutrients
Their valves prevent backflow
Their large diameter increases blood flow speed
Why is the left ventricle wall thicker than the right ventricle wall?
It pumps blood to the lungs
It pumps blood to the entire body
It receives blood from the lungs
It stores blood
Which process occurs when oxygen moves from the alveoli into the blood?
Filtration
Diffusion
Active transport
Osmosis
How does regular exercise benefit the cardiovascular system?
It increases blood pressure permanently
It strengthens the heart muscle and improves circulation
It decreases the number of red blood cells
It causes arteries to narrow
Which of the following best explains how the pulmonary and cardiovascular systems work together to maintain homeostasis?
The cardiovascular system produces oxygen for the body
The pulmonary system delivers oxygen to the blood, which the cardiovascular system transports to tissues
The pulmonary system pumps blood, and the cardiovascular system filters air
Both systems store nutrients
A person with a blocked coronary artery is at risk for which condition, and why?
Asthma, because airways are blocked
Heart attack, because blood flow to heart muscle is reduced
Stroke, because blood flow to the brain is increased
Anemia, because of low red blood cell count
Analyze how a decrease in lung capacity might affect the cardiovascular system during exercise.
It would have no effect
It would increase oxygen delivery to muscles
It would decrease oxygen supply, making the heart work harder
It would stop blood flow
Compare the roles of the skeletal and muscular systems in supporting cardiovascular health.
Both systems help pump blood directly
The skeletal system produces blood cells; the muscular system helps move blood through veins
Both systems filter blood
The muscular system produces blood cells; the skeletal system moves blood
Explain how poor posture could indirectly affect pulmonary function.
It increases lung capacity
It restricts chest expansion, reducing lung efficiency
It strengthens respiratory muscles
It has no effect
A person has a disease that weakens their diaphragm muscle. Predict how this would impact their pulmonary and cardiovascular health.
Breathing would become easier, and heart rate would decrease
Breathing would become more difficult, reducing oxygen supply to the body
Blood pressure would increase, but breathing would not change
There would be no impact
Evaluate why maintaining healthy bones is important for overall cardiovascular and pulmonary health.
Bones store oxygen for the body
Healthy bones produce blood cells needed for oxygen transport
Bones filter waste from the blood
Bones help the heart contract
Contrast the effects of muscular dystrophy and osteoporosis on cardiovascular and pulmonary health.
Both conditions only affect the lungs
Muscular dystrophy weakens muscles needed for breathing; osteoporosis reduces blood cell production
Both conditions increase heart strength
Muscular dystrophy increases bone density; osteoporosis strengthens muscles
A student is designing an experiment to test how aerobic exercise affects lung capacity and heart rate. Which of the following would be the best approach?
Measure lung capacity and heart rate before and after a period of regular aerobic exercise
Only measure heart rate after exercise
Only measure lung capacity before exercise
Ask participants how they feel after exercise
Label the front section of the muscular system
Gastronemious
Quadracept Group
Deltoid
Abdominal Rectis
Bicep

Soleus
Deltoid
Label the heart
