Order Of Heart Functions Flashcards
What is the first chamber of the heart that blood enters after returning from the body?
The right atrium.
True or False: The tricuspid valve is located between the right atrium and the right ventricle.
True.
Fill in the blank: Blood moves from the right ventricle through the _____ valve into the pulmonary artery.
pulmonary.
What is the function of the pulmonary valve?
To prevent backflow of blood into the right ventricle.
After blood passes through the pulmonary arteries, where does it go?
To the lungs for oxygenation.
What is the next chamber the oxygenated blood enters after leaving the lungs?
The left atrium.
True or False: The mitral valve is located between the left atrium and the left ventricle.
True.
What is the purpose of the aortic valve?
To prevent backflow of blood into the left ventricle.
What is the sequence of blood flow starting from the right atrium?
Right atrium → tricuspid valve → right ventricle → pulmonary valve → pulmonary artery → lungs → pulmonary veins → left atrium → mitral valve → left ventricle → aortic valve → aorta.
Fill in the blank: Blood returns to the heart from the lungs via the _____ veins.
pulmonary.
What structure prevents the backflow of blood from the aorta into the left ventricle?
The aortic valve.
Which chamber of the heart has the thickest walls?
The left ventricle.
True or False: Blood is oxygenated in the right ventricle.
False.
What happens to blood in the lungs?
It becomes oxygenated.
What is the role of the heart valves?
To ensure one-way flow of blood through the heart.
