What is the largest artery in the body?
Aorta
The aorta carries oxygenated blood away from the heart to the body.
What is the main vein that carries deoxygenated blood to the heart?
Vena cava
Which artery carries deoxygenated blood from the heart to the lungs?
Pulmonary artery
What type of valve is a semilunar valve?
Arterial
Semilunar valves prevent backflow of blood into the ventricles.
Which veins return oxygenated blood from the lungs to the heart?
Pulmonary veins
There are four pulmonary veins, two from each lung.
Which chamber of the heart receives oxygenated blood from the pulmonary veins?
Left atrium
The left atrium pumps blood into the left ventricle.
Which chamber of the heart receives deoxygenated blood from the body?
Right atrium
The right atrium collects blood from the superior and inferior vena cava.
What is the name of the valve that prevents backflow from the aorta into the left ventricle?
Semilunar or aortic valve
This valve ensures one-way flow of blood out of the heart.
What type of valve is the tricuspid valve?
Atrioventricular
The tricuspid valve separates the right atrium from the right ventricle.
What are the tendons that support the atrioventricular valves called?
Chordae tendinae
These tendons anchor the valves to the papillary muscles.
What is the other name for the bicuspid valve?
Atrioventricular (bicuspid) valve
It is also known as the mitral valve.
Which chamber of the heart pumps oxygenated blood into the aorta?
Left ventricle
The left ventricle has the thickest walls to generate high pressure.
Which chamber of the heart pumps deoxygenated blood to the lungs?
Right ventricle
The right ventricle sends blood through the pulmonary artery.
What structure separates the left and right sides of the heart?
Septum
The septum prevents mixing of oxygenated and deoxygenated blood.
What is a section through the heart used to illustrate?
Anatomical structure and blood flow
Sections help visualize the arrangement of chambers and valves.
