What is the liver?

What are capillaries?
The heart contracts and relaxes in this two-phase cycle.
What is the cardiac cycle?

What is Earth (2.5 times)?
This chamber of the heart pumps oxygen-poor blood to the lungs.
What is the right ventricle?

What is the kidney?
The heart generates enough pressure to squirt blood this far.
What is 30 feet?
Name the two upper chambers of the heart.
What are the atria?
The circulatory system works closely with this system to deliver oxygen.
What is the respiratory system?
The cardiovascular system is often affected by this metabolic disease.
What is diabetes?
The brain relies on this artery for oxygenated blood.
What is the carotid artery?
This is the only organ that can continue working outside the body.
What is the heart?
This valve prevents blood from flowing back into the left ventricle.
What is the aortic valve?
This protein in red blood cells binds oxygen for transport.
What is hemoglobin?
This condition occurs when the heart can't pump enough blood to meet the body’s needs.
What is heart failure?
These paired organs oxygenate blood before it's sent to the heart.
What are the lungs?
The heart pumps this many gallons of blood every day.
