System Basics
This system circulates blood, oxygen, nutrients and waste through the body.
What is the cardiovascular (circulatory) system?
This is approximately how many times the heart beats per day.
What is about 100,000 times?
These vessels carry blood away from the heart.
What are arteries?
This type of blood is bright red.
What is oxygen-rich (oxygenated) blood?
This happens to heart rate when you begin exercising.
What is it increases?
This is the main goal of the circulatory system—keeping the body stable.
What is homeostasis?
This chamber pumps blood to the lungs.
What is the right ventricle?
These vessels carry blood back to the heart and have valves.
What are veins?
This type of blood is darker red.
What is oxygen-poor (deoxygenated) blood?
This increases when more blood is pumped per beat.
What is stroke volume?
These are the three main components of the circulatory system.
What are the heart, blood vessels, and blood?
What is the Pulmonary Artery?
These tiny vessels are where exchange happens.
What are capillaries?
This gas is delivered to body cells by the blood.
What is oxygen?
The system that receives less blood flow when you exercise.
What is the digestion system?
This is what the system transports in addition to oxygen and nutrients.
What are waste products?
This is the strongest chamber that pumps blood to the body.
What is the left ventricle?
This is the main function of capillaries. (3)
What is the exchange of oxygen, nutrients, and waste?
This waste gas is carried to the lungs to be removed.
What is carbon dioxide?
This is one long-term effect of regular exercise on the heart.
What is a lower resting heart rate OR stronger heart muscle?
