Heart Chambers
This chamber receives deoxygenated blood from the body.
What is the right atrium?
These vessels carry blood away from the heart.
What are arteries?
Blood enters the right atrium from these two large veins.
What are the superior and inferior vena cava?
Arteries typically carry this type of blood.
What is oxygenated blood?
This valve is located between the right atrium and right ventricle.
What is the tricuspid valve?
This chamber pumps oxygenated blood to the body.
What is the left ventricle?
These vessels carry blood toward the heart
What are veins?
After the right ventricle, blood flows through this valve to the lungs.
What is the pulmonary valve?
Veins typically carry this type of blood
What is deoxygenated blood?
This valve is located between the left atrium and left ventricle
What is the mitral (bicuspid) valve?
This chamber receives oxygenated blood from the lungs.
What is the left atrium?
These are the smallest blood vessels where gas exchange occurs.
What are capillaries?
Oxygenated blood returns from the lungs via these vessels.
What are the pulmonary veins?
This vein carries oxygenated blood from the lungs to the heart.
What is the pulmonary vein?
This valve prevents backflow into the right ventricle.
What is the pulmonary valve?
This chamber pumps deoxygenated blood to the lungs.
What is the right ventricle?
This is the largest artery in the body
What is the aorta?
Blood flows from the left atrium to this chamber.
What is the left ventricle?
This artery carries deoxygenated blood from the heart to the lungs.
What is the pulmonary artery?
This valve prevents backflow into the left ventricle.
What is the aortic valve?
These two chambers contract during atrial systole.
What are the right and left atria?
These vessels connect arteries to capillaries.
What are arterioles?
Complete the path: right atrium → tricuspid valve → right ventricle → pulmonary valve → __________ → lungs.
What is the pulmonary artery?
This process describes the exchange of gases in the lungs.
What is external respiration?
These structures anchor the heart valves and prevent prolapse.
What are the chordae tendineae and papillary muscles?
