Heart Flashcards
(26 cards)
What are the four main chambers of the heart?
The four main chambers are the right atrium, right ventricle, left atrium, and left ventricle.
Which chamber receives deoxygenated blood from the body?
The right atrium receives deoxygenated blood from the body.
What is the function of the right ventricle?
The right ventricle pumps deoxygenated blood to the lungs for oxygenation.
True or False: The left atrium receives oxygenated blood from the lungs.
True.
What does the left ventricle do?
The left ventricle pumps oxygenated blood to the rest of the body.
Fill in the blank: The _____ separates the right atrium from the right ventricle.
tricuspid valve
Which valve prevents backflow of blood from the left ventricle to the left atrium?
The mitral valve prevents backflow.
What is the role of the pulmonary valve?
The pulmonary valve controls blood flow from the right ventricle to the pulmonary arteries.
Fill in the blank: The _____ valve allows blood to flow from the left atrium to the left ventricle.
mitral
True or False: The heart has two atria and two ventricles.
True.
What is the purpose of the interatrial septum?
The interatrial septum separates the right and left atria.
What does the interventricular septum do?
The interventricular septum separates the right and left ventricles.
What chamber is the strongest and has the thickest walls?
The left ventricle is the strongest and has the thickest walls.
Which chamber of the heart has the lowest pressure?
The right atrium has the lowest pressure.
What is the primary function of the atria?
The primary function of the atria is to receive blood returning to the heart.
True or False: The ventricles are responsible for pumping blood out of the heart.
True.
What structure connects the heart to the lungs?
The pulmonary arteries and veins connect the heart to the lungs.
What type of blood does the left atrium receive?
The left atrium receives oxygenated blood from the lungs.
Fill in the blank: The _____ valve controls blood flow from the left ventricle to the aorta.
aortic
Which chamber has a thicker muscular wall, the right ventricle or the left ventricle?
The left ventricle has a thicker muscular wall.
What is the primary function of the right atrium?
The primary function of the right atrium is to receive deoxygenated blood from the body.
True or False: The heart chambers function independently of each other.
False.
What is the role of the heart valves?
Heart valves prevent backflow of blood and ensure unidirectional blood flow.
Fill in the blank: The _____ is located between the left atrium and left ventricle.
mitral valve
