How does the respiratory system work with circulatory system?
Always work independently from one another.
Work together to keep blood pumping to all parts of the body.
Work together only when we are active, and never when we are resting or sleeping.
Work together to deliver oxygen to cells and remove carbon dioxide from the body.
You're playing a soccer match, and as the game intensifies, you notice you're breathing harder. How does your respiratory system respond to the increased physical demand?
Your lungs shrink to reduce oxygen intake.
Your breathing rate increases to supply more oxygen to your muscles.
Your breathing slows down as your muscles use less oxygen.
Your respiratory system stops working because you're using too much energy.
While running up a hill, your body demands more oxygen. How does your respiratory system adjust to this increased need?
Your lungs expand, and you take deeper, faster breaths to get more oxygen.
You start holding your breath to save oxygen.
Your breathing stays steady, regardless of the activity level.
Your lungs stop working to conserve energy.
Which of the following best describe the circulatory system?
It is the framework of the body.
the system that delivers oxygen and nutrients to the body cells
Its main organs are the lungs which carry out exchange of gases
the control center of the body
It is the large network of arteries, veins and capillaries which are pathways for the blood to deliver nutrients to the cells.
blood
spinal cord
blood vessels
intestines
Which of the following IS NOT a disease or disorder of the respiratory system?
lung cancer
emphysema
asthma
high blood pressure
Your doctor suggests exercising regularly. How does physical activity help maintain a healthy circulatory system?
It increases your cholesterol levels.
It strengthens the heart and improves blood circulation.
It slows down blood flow, preventing heart strain.
It weakens your heart over time.
You’re considering cutting down on your salt intake. Why is this a good decision for your circulatory system?
Salt improves blood circulation.
Salt has no effect on the circulatory system.
Eating more salt will lower your cholesterol.
Too much salt can raise blood pressure, increasing the risk of heart disease.
A patient complains of constant fatigue, pale skin, and dizziness. Tests show a low red blood cell count. Which circulatory system disorder are they most likely suffering from?
Hypertension
Stroke
Anemia
Palpitations
A person suddenly loses the ability to move the right side of their body and has trouble speaking. What circulatory disorder is most likely responsible?
Heart Attack
Stroke
Anemia
Hypertension
During a routine check-up, a doctor tells Danny that there is a problem with one of his heart valves. Based on this information, what findings might be related to Danny’s condition?
He may have difficulty digesting food because valves help with digestion.
He might have low oxygen levels because valves directly control oxygen levels in the blood.
He might experience blood being pushed forcefully into his lungs because valves help direct blood flow.
He might have blood flowing backward in the heart because valves prevent backward flow of blood.
Laura’s doctor explains her heart valve problem, where blood flows backward through a valve. What effect could this have on Laura’s heart?
Her blood vessels will become stronger and more elastic.
The heart must pump harder to maintain proper blood flow, leading to heart fatigue.
Her blood will circulate more quickly through the heart, improving oxygen delivery.
The heart will stop pumping blood, causing a stroke.
